Which stainless Steel Grade is better 304 or 316?
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 isnu2019t 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 304u2019s 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: u2022tHousehold appliances u2022tHeat exchangers u2022tFasteners u2022tPiping u2022tMaking structures within the environment that will alter steel u2022tCommercial food processing equipment u2022tWheel Covers u2022tStorage Tanks Grade 316 Stainless Steel 316 stainless-steel has the same material composition as 304 stainless-steel. However, additionally to high amounts of chromium and nickel, it also holds silicon, carbon, and manganese, with an enormous portion comprising of iron. Grade 316 stainless-steel includes a denser chemical composition. It holds a 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: u2022tMarine surroundings, especially those with high chloride concentrations u2022tMedical devices u2022tOutdoor electrical enclosures u2022tPharmaceutical Equipment u2022tRefinery equipment u2022tChemical 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. u2022tStainless 316 contains more nickel than stainless 304 u2022t304 contains more chromium than 316 u2022tStainless 304 usually consists of 18% chromium 8% nickel. u2022tStainless 316 is formed from 16% chromium, 10% nickel, and 2% molybdenum. u2022tBoth Grades of steels are durable and excellent resistance to corrosion and rust. u2022t304 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: u2022tThe application requires excellent formability. More molybdenum content in Grade 316 can have adverse effects on formability. u2022tThe application has cost concerns. Grade 304 is usually more cost-effective than Grade 316. Here are some situations where 316 stainless-steel is also best choice: u2022tWhen the environment includes a high amount of corrosive elements. u2022tIf the material will be exposed to water consistently or placed underwater. u2022tIt is used in the application where formability is less concerned and mainly focuses on durability. u2022tIn 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.
