Heat Treating ASTM A532 | Chrome White Iron | Penticton Foundry

Why Use Chrome White Iron. ASTM A532, or high chrome white iron, has superior abrasion resistance. It is particularly effective in machinery or equipment that experiences grinding, gouging abrasion or crushing. It can significantly reduce downtime and outlasts AR plate and CCO ( by as much as 20 times in the case of CCO) in abrasion …
