316 Stainless Steel plate : Composition, Properties
Leave a message
What is 316 stainless steel plate?
316 stainless steel plate is a molybdenum-containing 18Cr-10Ni austenitic stainless steel. Because it contains 2%-3% molybdenum, its corrosion resistance is better than 304, especially resistance to pitting and crevice corrosion in chloride environments. It also has good toughness, good low-temperature performance, and is non-magnetic. Molybdenum also improves its heat resistance and wear resistance, making it suitable for marine and other fields. This is also its main difference from the 304 series.

What is the difference between 316 and 316l composition?
While both contain chromium for surface protection and nickel for enhanced ductility, 316 has a higher maximum carbon content of 0.08%. In contrast, 316L has a maximum of 0.03% carbon content.

What is the difference between SS 304 and 316?
The simple answer is 304 contains 18% chromium and 8% nickel while 316 contains 16% chromium, 10% nickel and 2% molybdenum. The molybdenum is added to help resist corrosion to chlorides (like sea water and de-icing salts).
What are the disadvantages of 316 stainless steel?
While 316 stainless steel offers excellent corrosion resistance, it does have some drawbacks. The primary disadvantages are its higher cost compared to other grades like 304, and its lower machinability and formability. It can also be susceptible to stress corrosion cracking in certain harsh environments.
Is 316 stainless steel good quality?
Yes, 316 stainless steel is generally considered a good choice for many applications due to its excellent corrosion resistance, high strength, and durability. It is particularly well-suited for environments exposed to chlorides and acids, as well as for high-temperature applications.
