Product information

Grade: SUS316J1 
SUS316J1 is an austenitic stainless steel. It is derived from 316 stainless steel by adding copper elements, which significantly enhances its corrosion resistance and pitting resistance. It performs particularly well in chloride environments and under marine climatic conditions. Its chemical composition includes carbon (C ≤ 0.08%), chromium (Cr 17.00% - 19.00%), nickel (Ni 10.00% - 14.00%), molybdenum (Mo 1.20% - 2.75%), and copper (Cu 1.00% - 2.50%).
Corrosion resistance
It performs exceptionally well in acidic environments such as sulfuric acid and phosphoric acid, and has superior resistance to pitting and crevice corrosion compared to ordinary 316 steel. It is particularly suitable for marine engineering and chemical equipment. The low-carbon design (carbon content ≤ 0.08%) reduces the risk of intergranular corrosion at the welding site. Mechanical properties
‌Strength‌: Tensile strength ≥ 424 MPa, Yield strength ≥ 341 MPa
‌Ductility‌: Post-rupture elongation ≥ 13%, Impact performance ≥ 21 J
‌Hardness‌: Brinell hardness ≤ 341 (HBW) Application fields
It is widely used in scenarios where high requirements for corrosion resistance and biocompatibility are necessary, such as food processing equipment, medical devices, chemical storage tanks, and ship accessories.

Product parameter

Chemical composition
The chemical composition of SUS316J1 stainless steel is as follows:
‌Carbon (C): ≤ 0.08%
‌Chromium (Cr): 17.00% - 19.00%
‌Nickel (Ni): 10.00% - 14.50%
‌Molybdenum (Mo): 1.20% - 2.75%
‌Copper (Cu): 1.00% - 2.50%
‌Silicon (Si): ≤ 1.00%
‌Phosphorus (P): ≤ 0.045%
‌Sulfur (S): ≤ 0.030%
This material is enhanced with copper elements on the basis of 316 stainless steel, further improving its corrosion resistance and pitting resistance, and is particularly suitable for acidic environments and marine engineering fields.
