Product introduction
27SiMn has good machinability and cold deformation plasticity. It maintains high strength and wear resistance during heat treatment and high toughness during water quenching. 27SiMn steel is widely used in automobile, petroleum, chemical industry, shipping industry, 27SiMn steel tubes are normalized and tempered, phosphate oiled inside and outside,  is generally used for manufacturing hot stamping parts requiring high toughness and wear resistance, such as various hydraulic parts.
