The late eighty`s, American technology of rare eath wear resistant steel was introduced into our country. The relevant experts researched and made many experiments. Then rare-earth wear-resistant steel had occupied the main position.Rare-earth wear-resistant steel is based on 40 steel. Cr, Ni, Si, Mo, Mn, Re elements are mixed in 40 steel forming low alloy steel which carbon content is 0.35~ 0.45%.
