[the]] : chemical composition of high manganese steel, high carbon wear-resisting of carbon of quality score reaches wC = 0.9 1.45% ~ ~ ~ 11, 14 wMn =. Because of high manganese steel extremely cold deformation wear, cutting processing, thus to wear high manganese steel pieces of as-cast mostly.
[by]] : the letters "brand" (steel) ZG said after element symbols attached to its content Mn expressed as percentage. GB/T 5680-1998 ZGMn: containing five brands of 13-1, 2, ZGMn 13-13-3, ZGMn ZGMn 13-4, 5, ZGMn 13 - these five brands of composition and properties of slightly different.
[the]] : "heat" -- will toughening water heated to 10 ~ steel 10.5 degrees Celsius, heat preservation period of time, all of the steel, carbon austenite dissolve in water, then in the cold, too fast, get single carbon austenitic organization. Water hardness is not high toughness processing (180-220HBS). When it was severe shock or larger pressure, produced surface rapidly, and accompanied by hardening processing martensite transformation, make the surface hardness to 52-56 HRC and high wear resistance, and heart is still part of austenitic, good toughness, to bear strong impact.
[applications] : must pay attention to high manganese steel must wear of the impact or larger pressure, can make surface hardening processing, which shows its high abrasion resistance, high manganese steel is not wear-resisting of wear.
