jaw

The tooth plate of the jaw crusher is cast from ZGMn13Cr2 mat erial. A certain amount of chromium is added

to the original high man ganese steel to improve the hardness of the product, and water toug hening treatment

is carried out at the same time. After water toughen ing treatment, the casting has high tensile strength, toughness, 

plasti city and alkalinity, making the tooth plate more durable. When subjec ted to severe impact and strong pressure

deformation during use, th e surface is work-hardened and martensite is formed, thus forming a highly wear-resistant

surface layer, while the inner layer maintains ex cellent toughness. Even if it is corroded to a very thin layer, it can 

withstand a large impact load.
