Description
316L Stainless Steel Pipe Brief Introdcution
316L stainless steel pipe is a hollow long round steel, mainly is widely used in petroleum, chemical, medical, food, light industry, machinery, instrument and other industrial pipeline and mechanical structure parts, etc.
In addition, in bending and torsion strength, the weight is lighter, therefore it is also widely used to make mechanical parts and engineering structures. Futher It is also used to produce all kinds of conventional weapons, guns and shells.
What is Stainless Steel 316L Pipe?
SS316L TP316L AISI316L 316L Stainless Steel Pipe mainly contains chemicals of 16.00% – 18.00% Cr, 10.00% – 14.00% Ni, 2.00% – 3.00% Mo, ≤0.030% C, which is also a derivative steel of 18-8 type austenitic stainless steel with Excellent corrosion resistance.
The American standard stipulates that the Ni content of 316L is 10-14%, and the Japanese standard stipulates that the Ni content of 316L is 12-15%.
According to the minimum standard, there is a 2% difference in Ni content between the American standard and the Japanese standard, which is still quite huge in terms of price. Therefore, customers still need to see clearly when purchasing 316L products, whether the product is based on ASTM/JIS/DIN /EN/GOST standards.
The Mo content of 316L Stainless Steel Pipe makes the steel have excellent resistance to pitting corrosion and can be safely used in environments containing halogen ions such as Cl-.
Because 316L is mainly used for its chemical properties, therefore steel mills have slightly lower requirements for surface inspection of 316L (relative to 304). Customers with higher requirements on the surface should strengthen the surface inspection.
