What is the difference between steel grade 316 and 304?

May 19, 2024 - by thesundayheadlines

Understanding the Differences Between Steel Grades 316 and 304

Stainless steel is a versatile and widely used material in various industries due to its durability, corrosion resistance, and aesthetic appeal. Among the numerous grades of stainless steel, grades 316 and 304 are two of the most common and frequently used. While they may appear similar at first glance, there are significant differences between these two grades that make each suitable for specific applications. In this blog, we’ll explore the key differences between stainless steel grades 316 and 304.

Understanding the Differences Between Steel Grades 316 and 304

Composition

The primary difference between 316 and 304 stainless steel lies in their chemical composition. Both are austenitic stainless steels, but they have distinct variations in their alloying elements:

Grade 304: The most common form of stainless steel, containing approximately 18% chromium and 8% nickel. Its composition makes it highly resistant to oxidation and corrosion, and it is often referred to as “18/8” stainless steel.
Grade 316: Contains about 16% chromium, 10% nickel, and 2% molybdenum. The addition of molybdenum enhances its corrosion resistance, particularly against chlorides and other industrial solvents.

Corrosion Resistance

One of the key factors that set these two grades apart is their ability to resist corrosion:

304 Stainless Steel: Offers excellent corrosion resistance in a wide range of environments, making it suitable for general purposes. However, it can be susceptible to pitting and crevice corrosion in chloride-rich environments such as coastal areas and areas exposed to de-icing salts.
316 Stainless Steel: The addition of molybdenum significantly improves its resistance to chloride-induced corrosion, making it ideal for marine applications, chemical processing, and environments with higher exposure to corrosive elements.

Mechanical Properties

Both grades share similar mechanical properties, but some differences exist due to their chemical composition:

304 Stainless Steel: Exhibits good formability and weldability, making it easy to fabricate and work with. It is strong and durable but may not perform as well as 316 in highly corrosive environments.
316 Stainless Steel: Offers similar strength and formability but excels in high-stress environments due to its superior corrosion resistance. It is often chosen for applications where durability and longevity in harsh conditions are crucial.

Applications

The choice between 316 and 304 stainless steel often comes down to the specific requirements of the application:

304 Stainless Steel: Commonly used in kitchen equipment, food processing, automotive parts, and architectural applications. Its versatility and cost-effectiveness make it a popular choice for a wide range of uses.
316 Stainless Steel: Preferred for more demanding applications such as marine environments, chemical processing equipment, medical devices, and pharmaceutical manufacturing. Its enhanced corrosion resistance and ability to withstand harsh conditions make it ideal for these settings.

Cost

Another practical consideration when choosing between 316 and 304 stainless steel is cost:

304 Stainless Steel: Generally less expensive due to the absence of molybdenum, making it a cost-effective choice for many applications.
316 Stainless Steel: More expensive due to the addition of molybdenum and its superior corrosion resistance. The higher initial cost can be justified by its longer lifespan and better performance in corrosive environments.

Conclusion

In summary, the choice between stainless steel grades 316 and 304 depends on the specific requirements of your application. While 304 stainless steel is versatile, cost-effective, and suitable for a wide range of uses, 316 stainless steel offers superior corrosion resistance and durability in harsh environments. Understanding these differences will help you select the right material for your needs, ensuring longevity and optimal performance in your projects.

By considering factors such as composition, corrosion resistance, mechanical properties, applications, and cost, you can make an informed decision that best suits your specific requirements. Whether you need the all-around capabilities of 304 or the enhanced performance of 316, stainless steel remains a reliable and essential material in various industries.

“Google Issues Apology to Government Over Gemini’s Inconsistent Results on PM Modi”

March 4, 2024March 5, 2024 - by Chirag Goyal

NEW DELHI: American tech giant Google issued an apology to the government for the unsubstantiated comments made by its AI platform Gemini regarding PM Modi, acknowledging its platform as ‘unreliable,’ Minister of State for IT & Electronics Rajeev Chandrasekhar informed TOI.

“We had sent them a notice, seeking an explanation on the unsubstantiated results thrown up by Gemini regarding a particular query on PM Modi. They replied, stating, ‘Sorry, the platform is unreliable,'” the minister revealed, coinciding with the government’s announcement that AI platforms will now require a ‘permit’ to operate in the country. “That’s an inadequate response,” criticized the minister, highlighting a concerning trend among AI platforms offering ‘consumer solutions’ during trial phases.

The minister emphasized that India cannot serve as a testing ground for AI platforms, particularly as they face increasing global scrutiny for providing biased, misinformed, or unverified results. “AI data is being released from labs straight onto the public internet, without proper testing or safeguards. Then, when caught, they apologize, citing unreliability.”

Citing Google’s Gemini as an example, he stated, “Google Gemini is a prime example. They transitioned from the lab to the public internet without fear of consequences. And when confronted, they dismiss it, claiming the information is unreliable.”

The minister underscored that the Indian government will not permit underdeveloped platforms to offer full-fledged services without proper disclosures to users regarding potential misinformation or unlawfulness.
“We’ve made it clear that the Indian internet is not a testing ground. If you’re transitioning from the lab and it’s still unreliable, you must include a disclaimer. Users must be explicitly informed through consent forms and terms of use that this platform is under trial and may produce inaccurate or unlawful content.”

The minister emphasized that AI platforms cannot treat India as an extension of their research and development laboratories. “Indian internet and consumers cannot be considered mere testing grounds. Respect for Indian consumers, our digital citizens, is paramount. It is imperative for AI platforms to explicitly warn Indian users about potential errors, unreliability, and inaccuracies in their platforms. Users must be fully aware and informed before engaging with such platforms.”

Furthermore, the minister highlighted the legal repercussions for AI platforms found violating Indian IT and criminal laws. “The Indian legal framework, including the IT Act and IT Rules, clearly delineates 12 types of unlawful content. If AI platforms generate such unlawful content, they cannot claim unreliability as a defense. Prosecution will ensue.”

The minister condemned Gemini’s dissemination of unverified and unsubstantiated results as “reckless, irresponsible, and disrespectful” towards Indian consumers. “Taking Indian digital citizens for granted will not be tolerated, and appropriate measures will be taken to address such behavior.”

The government’s recent advisory for AI-led startups underscores the importance of labeling unverified information as potentially false and error-prone. This advisory follows a previous notice issued nearly two-and-a-half months ago regarding deepfakes, in response to numerous instances of synthetically-generated content infiltrating social media and online platforms.

Google Takes Down Matrimony.com, Naukri, 99acres, Altt, and Other Indian Apps from Play Store

March 1, 2024March 2, 2024 - by Chirag Goyal

Google has taken down the apps of 10 Indian companies, including Info Edge, 99acres, BharatMatrimony, Truly Madly, QuackQuack, Stage, Altt, and Kuku FM, due to non-payment of service fees. In response, Sanjeev Bikhchandani and Murugavel Janakiraman have made statements, and Commerce and Industry Minister Piyush Goyal has been tagged in a post.

On Friday, March 1, Google initiated the removal of apps belonging to 10 Indian companies due to their failure to pay service fees. This action came after Google published a blog earlier in the day, stating that despite being “very established”, these companies hadn’t paid the required fees for using the platform. Although Google didn’t disclose the company names initially, it was revealed that the affected apps included matrimonial services.

Google emphasized its right to charge fees, stating, “For years, no court or regulator has denied Google Play’s right to charge,” adding that the Supreme Court had also declined to intervene.

Reports indicate that Info Edge’s flagship apps Naukri.com and 99acres, along with BharatMatrimony and Shaadi.com, were removed by Google. Additionally, online dating apps Truly Madly and QuackQuack, vernacular video-streaming platform Stage, Balaji Telefilms’ Altt, and audio streaming and podcast app Kuku FM were among those taken down.

The dispute revolves around Google’s imposition of fees ranging from 11% to 26% on in-app payments after the Competition Commission of India (CCI) ordered the elimination of the previous fee structure of 15% to 30%.

Google claims to have provided over three years for developers to prepare for the changes, including three weeks after the Supreme Court’s order. As a result, the company asserts it is taking necessary steps to enforce its policies consistently across the ecosystem.

In response, Info Edge founder Sanjeev Bikhchandani stated that the company had settled all outstanding Google invoices promptly and complied with policies. He urged for the establishment of an App Store/Play Store integrated into Digital Public Infrastructure, akin to UPI and ONDC. Meanwhile, Bharat Matrimony founder Murugavel Janakiraman described Google’s actions as a “dark day” for the internet in India.

Tamil Nadu Minister Releases Ad for ISRO, Features Chinese Flag on Missile Instead of Indian

February 28, 2024February 29, 2024 - by Chirag Goyal

An advertisement promoting a new spaceport operated by the Indian Space Research Organisation (ISRO) in Tamil Nadu has sparked controversy after featuring a rocket adorned with the flag of China, leaving the state government embarrassed.

The advertisement, reportedly issued by State Fisheries Minister Anita Radhakrishnan, was meant to commemorate Prime Minister Narendra Modi laying the foundation stone for the ISRO spaceport in Kulasekarapattinam. It aimed to highlight the efforts of former Chief Minister Karunanidhi and his son, current Chief Minister MK Stalin, in bringing the project to fruition.

However, the ad unintentionally displayed a computer-generated rocket with the Chinese national flag, leading to criticism from the Bharatiya Janata Party (BJP) directed at the ruling Dravida Munnetra Kazhagam (DMK).

Prime Minister Modi, taking a jab at the DMK, accused the party of appropriating credit for projects initiated by the BJP-led Centre. “DMK is a party that takes credit for work it hasn’t done. Everyone knows they put their stickers on our schemes. Now, they’ve gone too far by affixing Chinese stickers to claim credit for the ISRO launch pad in Tamil Nadu,” PM Modi stated at a rally in Tirunelveli.

“They refuse to acknowledge India’s space advancements, and with taxpayers’ money, they advertise without even featuring India’s space achievements,” he added. BJP state president K Annamalai also condemned the ad, which appeared in local newspapers, and accused the DMK of showing “disregard for our country’s sovereignty.”

“This advertisement… reflects the DMK’s allegiance to China. The DMK, steeped in corruption, has been eager to claim credit since the announcement of ISRO’s second launch pad. Their desperation only highlights their attempt to bury their past misdeeds,” Annamalai wrote on X (formerly Twitter).

He further contextualized the situation, recalling an incident from 60 years ago when Tamil Nadu’s initial proposal to host ISRO’s first launch pad was marred by incompetence.
