316L vs 904L Austenitic Stainless Steels: Standard Marine-Grade vs Strong Acid Resistance316H Stainless Steel High-CarbonASTM 201 Stainless Steel: Properties, Applications, and Limitations

The chemical balance of 1.4420 S31655 is strictly controlled during our smelting process to ensure optimal performance. The addition of Nitrogen is key to its enhanced mechanical properties.

Grade C (Carbon) Si (Silicon) Mn (Manganese) P (Phosphorus) S (Sulfur) Cr (Chromium) Ni (Nickel) Mo (Molybdenum) N (Nitrogen)
1.4420 / S31655 ≤ 0.030% ≤ 1.00% ≤ 2.00% ≤ 0.045% ≤ 0.015% 16.5 – 18.5% 10.5 – 13.5% 2.0 – 3.0% 0.12 – 0.22%

 

 

1.4420 S31655 exhibits higher yield strength than conventional austenitic stainless steels due to solid solution strengthening from Nitrogen. Below are typical properties at room temperature.

Property Value (Typical) Unit
Tensile Strength (Rm) 600 – 850 MPa
Yield Strength (Rp0.2) ≥ 290 MPa
Elongation (A5) ≥ 40 %
Hardness (HB) ≤ 215 HB
