27SiMn steel bar

The material 27SiMn has high hardenability. 27SiMn teel’s toughness decreases not much as heat treatment, but material 27SiMn has very high strength and abrasion resistance, especially when water quench, grade 27SiMn still has high toughness. However 27SiMn steel is sensitivity to the white dots very much and 27SiMn is sensitivity to temper brittleness tendency and overheating when heat treatment.
27SiMn is mainly used under tempering condition and used in the manufacture of high toughness and wear resistance of hot stamping.27SiMn can also used under fire or hot rolling using supply condition, such as the tractor caterpillar pin, etc.
