Chemical element

 

The chemical composition of 316L stainless steel mainly includes chromium (Cr), nickel (Ni), molybdenum (Mo) and other elements, the specific content is as follows:

 

Chemical element content
C ≤0.030%
Si ≤1.00%
Mn ≤2.00%
S ≤0.030%
P ≤0.045%
Cr 16.00% ~ 18.00%
Ni 10.00% ~ 14.00%
Mo 2.00% ~ 3.00%

 

Performance characteristics


Corrosion resistance:

1) 316L has excellent intergranular corrosion resistance due to its ultra-low carbon characteristics and the addition of molybdenum.
2) Excellent corrosion resistance to various organic acids, inorganic acids, alkalinity and salts, especially suitable for harsh corrosive environments.
3) Under high temperature conditions, when the concentration of sulfuric acid is lower than 15% or higher than 85%, 316L stainless steel has a wide range of uses.
Mechanical properties:
1) 316L has high tensile strength and yield strength, while maintaining good elongation and section shrinkage.
2) Moderate hardness, easy to process and cut, reduce the production cost.
Weldability:
Good welding performance, suitable for multi-layer welding, no need for heat treatment after welding, no knife edge corrosion tendency after welding.
Processing properties:
With good processing performance, it is convenient to process into various shapes and sizes of parts to meet various engineering needs.
