27SiMn alloy steel pipe

Toughness of the 27SiMn alloy steel pipe is superior to the performance of 30Mn2 steel, quenching is higher, in the critical water quenching through diameter of 8 ~ 22mm, good cutting, cold plastic deformation and the weldability medium; also steel in heat treatment toughness reduce not much, but very high strength and wear resistance, especially water quenching is higher, but the steel to hydrogen flaking, heat treatment is temper brittleness and overheat sensitivity.
