The effect of nitrogen on crystal grain for metastabl austenitic manganese steel was studied. The result indicated that the attachment of nitrogen element in the interface between the crystal and liquid steel will influence the formation mechanism of crystal, that the existing of nitrogen element hinder the diffusion of atoms, increase the free energy of critical nucleation, raise homogeneous nucleation rate of crystal and lower the growing velocity of crystal accordingly, and refine the crystal grain finally for casting steel. And the effect degree of nitrogen will be influenced by the specialty of nitrogen on critical micelle concentration. During heat treatment, because of covalent bond between nitrogen atom and iron atom and manganese atom, the existing of nitrogen element in the boundary of crystal or the attachment of nitrogen element on the face of crystal will hinder the diffusion of iron atoms and manganese atoms, so that lower the growing velocity of crystal and refine the crystal grain of steel finally after heat treatment.

Abstract 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.
