Common Wear-Resistant Finished Products
High carbon manganese steel is processed into various wear-resistant finished components, depending on industrial requirements:
-
Crusher Liners: ジョープレート, cone liners, インパクトプレート
-
Grinding Mill Liners: Ball mill liners, SAG mill liners
-
Earth-Moving Components: Bucket liners, shovel teeth, dipper edges
-
Chutes and Hoppers: Liners for handling abrasive materials
-
Heavy Machinery Parts: Slag plates, 画面, and impact plates
These components rely on surface hardening under impact, where the steel’s work-hardened layer protects the component while maintaining a tough, 延性コア, significantly extending service life.
