27SiMn belongs to the national standard alloy structural steel Bai, executive standard: dugb / t17396-1998 seamless steel pipe for hydraulic prop

The properties of 27SiMn Steel are better than those of dao30mn2 steel, with high hardenability. The critical quenching diameter in water is 8-22mm, with good machinability and moderate cold deformation plasticity and weldability. In addition, the toughness of 27SiMn Steel is not much reduced during heat treatment, but it has high strength and wear resistance, especially high toughness during water quenching. However, the steel is sensitive to white spots and has temper embrittlement during heat treatment Sexual orientation and overheating sensitivity. This kind of steel is mainly used in the quenched and tempered state to make hot stamping parts with high toughness and wear resistance; it can also be used in normalized or hot-rolled supply state, such as tractor track pin, etc.

The chemical composition of 27SiMn is as follows
