● Grade: G20C2rMn2Mo
● Material Name: carburizing bearing steel
● Features:
High surface hardness after carburizing, the Ministry of toughness and heart, can withstand a strong impact on load. Compared with G20Cr2Ni4, carburizing speed, easier to cementite formation of coarse carbide layer, spread easily eliminated.
● Application:
For high-impact loading conditions, the work of large and large and medium-sized bearing parts, and the shaft, gear and so on.
● Chemical composition:
● Heat treatment system:
880 ℃ ± 20 ℃, 810 ℃ ± 20 ℃ oil quenched, 180 ℃ ~ 200 ℃ tempering, air-cooled.
Surface hardness 62HRC, core hardness 41.5HRC, carburizing depth of 2.3mm
