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 HRc. GB 20Cr steel Annealing delivery hardenss less than 250HB.20Cr With a lower carbon content range, So GB 20Cr alloy steel have good weldability. Related Specifications ASTM A29/A29M DIN EN 10083/3 JIS G4053 GB/T 3077
40Cr Steel CNC Machining Parts CNC Mechanical Steel CNC Machining 40Cr Steel Parts. 40Cr Steel Is The Standard Steel Grade Of GB In Our Country, And 40Cr Steel Is One Of The Most Widely Used Steels In Machinery Manufacturing Industry. After Quenching And Tempering, It Has Good Comprehensive Mechanical Properties, Good Low Temperature Impact Toughness And Low Notch Sensitivity.
