astm a242 a588 alloy steel sheet plate decorative wall cldding astm a242 corten steel plate
The ASTM A242 specification is the standard specification for high strength low alloy structural steel for structural members where weight savings and atmospheric corrosion resistance are important. The main alloying elements of ASTM A242 corten steel plate are chromium nickel and copper with added phosphorous which gives it excellent self protecting qualities.
