Corten B steel plate chemical composition and mechanical properties

Corten B steel plate can be used to manufacture low alloy structural steel for automobiles, bridges, towers, containers and other steel structures. Compared with ordinary carbon steel, Corten B steel plate has better atmospheric corrosion resistance.

Compared with stainless steel, Corten B steel plate only contains a small amount of alloy elements, such as phosphorus, copper, chromium, nickel, molybdenum, niobium, vanadium, titanium, etc. The total amount of alloy elements in Corten B steel plate is only a few percent, unlike stainless steel, which reaches more than 10 percent, so the price is relatively low.
