Which stainless Steel Grade is better 304 or 316?

1. Which stainless Steel Grade is better 304 or 316? When selecting stainless-steel that has to endure corrosive environments, due to that austenitic stainless steels are typically used. Austenitic stainless-steel grades are the best one choice for materials which will endure corrosive environments. Additionally, many austenitic stainless steels are weld able and formable. Two of the more commonly used grades of austenitic stainless-steel are grades 304 and 316. Most stainless-steel alloys have good or excellent resistance to corrosion in normal conditions. Stainless-steel alloys tend to possess a powerful, but thin, a layer of oxide that prevents rusting, hence the name Stainless-Steel. In mildly corrosive environments at normal ambient temperatures, the corrosion resistance of grade 316 and grade 304 stainless isn’t very different. This blog will examine the difference between 304 and 316 chrome steel and you will get a clear idea about which type to be used for various applications. Grade 304 Stainless Steel Grade 304 could be a basic austenitic stainless-steel. It contains a high level of nickel and chromium, with the number of chromium ranging from 18 to 20 by weight and nickel weighing in at between 8 and 10.5%. Grade 304’s other alloying elements include silicon and manganese with iron comprising the remaining chemical composition. Chromium and nickel give 304 stainless-steel its high corrosion resistance. Common applications for 304 Stainless-steel include: Household appliances Heat exchangers Fasteners Piping Making structures within the environment that will alter steel Commercial food processing equipment Wheel Covers Storage Tanks

2. Grade 316 Stainless Steel 316 stainless-steel has the However, additionally to high amounts of chromium and nickel, it also holds silicon, carbon, and manganese, with an enormous portion same material composition as 304 stainless-steel. comprising of iron. Grade major amount of molybdenum of about 2-3% in weight compared to the traces found in 304. The upper molybdenum in 316 results in higher corrosion resistance than in 304. 316 stainless-steel does well in salty water, making it ideal for marine applications. Other common applications of 316 Stainless-steel are: 316 stainless-steel includes a denser chemical composition. It holds a Marine surroundings, especially those with high chloride concentrations Medical devices Outdoor electrical enclosures Pharmaceutical Equipment Refinery equipment Chemical storage equipment and for chemical processing Difference between 304 & 316 Grade The most basic difference between the grades of steel is that the presence of molybdenum in stainless 316. Molybdenum is a substance used for the strengthening and hardening of steel. Its main function in stainless 316 is to assist fight corrosion from chlorides. Stainless 316 contains more nickel than stainless 304 304 contains more chromium than 316 Stainless 304 usually consists of 18% chromium 8% nickel. Stainless 316 is formed from 16% chromium, 10% nickel, and 2% molybdenum. Both Grades of steels are durable and excellent resistance to corrosion and rust. 304 stainless more cheaper in cost compared to 316 Which Grade to be choose 304 or 316? There is some situation which set apart the both grades, but both are legend on their turf. Here are some situations where 304 stainless-steel could also be the better choice: The application requires excellent formability. More molybdenum content in Grade 316 can have adverse effects on formability. The application has cost concerns. Grade 304 is usually more cost-effective than Grade 316.

3. Here are some situations where 316 stainless-steel is also best choice: When the environment includes a high amount of corrosive elements. If the material will be exposed to water consistently or placed underwater. It is used in the application where formability is less concerned and mainly focuses on durability. In the application where non-magnetic steel is required To summarize, 316 steel is worth the expense if you need superior corrosion resistance and durability. If not then 304 S.S will serve your need just better. Santosh Steel Industries is one of the leading Stainless Steel manufacturer and Exporter in India.
