This gives our Tensamang steel almost five times the hardness of mild steel and almost three times the hardness of annealed stainless steel. 1. The most straightforward answer is that Rockwell hardness refers to how resistant a metal object such as a knife blade is to penetration and permanent deformation from another material. The first difference between manganese steel and carbon steel is that mangalloy softens rather than hardens when rapidly cooled, then restores the ductility from a work-hardened state. . On the Brinell hardness scale the product reaches a hardness score of 550 BHN through work hardening. 2. It is generally believed that manganese steel has poor abrasion resistance unless it has been work-hardened. Non-synthetic, non-magnetic, high manganese stainless for joining and buffer layers. Most steels are iron-based. It's awfully close in composition to 1095 steel. 4. Sulfur S 0.02% : Improves machinability. See also.
