GB/T 3077 20CR alloy steel

GB/T 3077 20CR steel main features:

GB 20Cr 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 HR c. GB 20Cr steel Annealing delivery hardness less than 250HB.20Cr with a lower carbon content range, So GB 20Cr alloy steel have good weld ability.

GB/T 3077 20CR steel application:
20CR steel is mainly used for making cam shaft, driven gears of small tractor. This kind of steel also is mostly used in the manufacturing of the high demand  heart intensity, surface under wear, section under 30 mm or complex and not big load carburized parts (oil quenching), such as: machine tool transmission gear, gear shaft, worm and piston pins, claw clutch, etc.
