The main components of 304 stainless steel include 18% chromium and 8% nickel. This high chromium and high nickel composition makes it have excellent corrosion resistance. 430 stainless steel mainly contains more than 16% chromium and no nickel, which makes it less corrosion resistant.

SS304 (AISI 304) is the most commonly used stainless steel in the manufacture of other stainless steel materials and is usually purchased in the cold or annealed condition. Similar to SUS304, SS304 also contains 18% Cr and 8% Ni, hence the name 18/8.
