Manganese content is the steel of 18 ％ of 11 ％ ～ to weigh tall manganese steel about. The commonly used chemical part that casts ZMn13 of tall manganese steel is: Mn content 14 ％ of 11 ％ ～ , c content 1.4 ％ of 1 ％ ～ , si content 1 ％ of 0.3 ％ ～ , ％ of P content <0.03, ％ of S content <0.05.

Tall manganese steel is steel of a kind of wear-resisting, the tall manganese steel that processes through Shui Ren can get taller plasticity and concussion tenacity. Alleged Shui Ren is handled, heat steel to 1000 ℃ ～ namely 1100 ℃ , heat preservation period of time, all dissolve enters the carbide that makes steel medium in austenite, cool quickly next, make carbide has not enough time from the separate out in austenite, held single even austenite organization thereby. The tall manganese steel that processes through Shui Ren calls tall manganese austenite steel. Its are mechanical function is: σ_B=980 MPa, σ_S=392 MPa, HB210, δ =80 ％ , α_KM of =2.94 MJ ／².

Tall manganese steel has very tall wearability, although its hardness has HB210 only, but S of its yield point σ is inferior, have the 40 ％ of σ B only, because this has taller plasticity and tenacity. Tall manganese steel is in get when outside pressure and concussion load, the plasticity with meeting very large generation is out of shape or machine sclerotic phenomenon badly, steel by acuteness aggrandizement, hardness rises significantly, can amount to HB450 ～ 550, because this had taller wearability.

Tall manganese steel can be divided for tall carbon steel of tall manganese wear-resisting, medium carbolic tall manganese does not have refractory steel of stainless steel of tall manganese of magnet steel, low carbon and tall manganese.
