Climax 6Mn-1Mo alloy is a lean austenitic manganese steel which develops a structure similar to that of the well-known Hadfield manganese steel after heat treatment. A lower carbon version of this alloy has been developed to give satisfactory performance in the as-cast condition. Largely because of lower manganese content, these alloys have better abrasion resistance but lower toughness and ductility than Hadfield steel. Both alloys are designed for the many applications where a combination of good wear resistance and moderate toughness is desirable. This datasheet provides information on composition, hardness, and tensile properties as well as fracture toughness. It also includes information on wear resistance as well as casting, heat treating, machining, joining, and surface treatment. Filing Code: SA-322.
