The Stainless Steel Composition
Mainly like all the Steel Plate, Stainless Steel also made from Iron (Fe). However, to make stainless more corrosion resistance the stainless manufacturer add other material such as chromium, nickel, etc that help the stainless steel to protect the surface and stop corrosion from spreading.
Below is the table of Stainless Steel composition according to its grade
Stainless Steel Grade | C (Carbon) | Ni (Nickel) | Cr (Chromium) | Mo (Molybdnenum) | Ti (Titanium) | S (Sulfur) |
