316L stainless steel pipe description
316L stainless steel pipe 316L stainless steel seamless pipe 316L stainless steel welded pipe
316L is a stainless steel material grade, AISI 316L is the
corresponding American grade, and sus 316L is the corresponding
Japanese grade. The unified number code in China is S31603, the
standard brand is 022Cr17Ni12Mo2 (new standard), and the old brand
is 00Cr17Ni14Mo2, indicating that it mainly contains Cr, Ni and Mo,
and the number indicates the approximate percentage. The national
standard is GB/T 20878-2007 (current edition).
316L is widely used in the chemical industry due to its excellent
corrosion resistance. 316L is also a derivative steel of 18-8
austenitic stainless steel, with 2-3% Mo added. On the basis of
316L, many steel grades are also derived. For example, 316Ti is
derived by adding a small amount of Ti, 316N is derived by adding a
small amount of N, and 317L is derived by increasing the content of
Ni and Mo.
Most of the existing 316L products on the market are produced
according to American standards. In consideration of cost, steel
mills generally limit the Ni content of products as far as
possible. According to the American standard, the Ni content of
316L is 10~14%, while according to the Japanese standard, the Ni
content of 316L is 12~15%. According to the minimum standard, there
is a 2% difference in Ni content between American Standard and
Japanese Standard, which is quite huge in terms of price.
Therefore, customers need to see clearly when purchasing 316L
products, whether the products refer to ASTM or JIS standards.
The Mo content of 316L makes the steel have excellent corrosion
resistance and can be safely used in the environment containing Cl
- and other halogen ions. As the 316L is mainly used for its
chemical properties, the steel plant has slightly lower
requirements on the surface inspection of the 316L (compared with
304), and customers with higher requirements on the surface should
strengthen the surface inspection.
