GB 40CR alloy Steel is a high quality Quenched and Tempered Alloy Structural steel, It belong to the high quality low carbon,Low alloy chromium, molybdenum, nickel case hardening steel. Oil Quenched & Tempered Hardness is 28-34 HRc. GB 40CR steel Annealing delivery hardenss less than 250HB.40CR With a lower carbon content range, So GB 40CR alloy steel have good weldability.

50Mn-60Mn hot rolled steel round bars

50Mn round steel is used to manufacture heat-treated parts that require high wear resistance and are subjected to high loads, such as gears, gear shafts, and mandrels with a section below 80mm.

W6Mo5Cr4V2(M2) hot rolled steel round bars

M2 is a molybdenum high-speed steel, which has the advantages of small carbide non-uniformity and high toughness. It is easy to overheat, so the quenching temperature should be strictly controlled, and the protection requirements for heat treatment should be strict
