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
GB 20CrMo steel is a kind of Chinese alloy steel for engineering and mechanical structure purpose, which is generally used in quenching or tempering or carburizing and quenching. 20CrMo material has high heat strength, good hardenability, no temper brittleness, 25CrMo4, 1.7218, AISI 4130 - Engineering steelIt exhibits very good strength properties, high ductility, weldability and good hardenability. Compared to the 35HM and 34CrMo4 grades, after heat treatment it has slightly worse strengths, but it makes up for the lower properties with much better ductility.
