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.
