temperature. Subsequently, to simulate the thermal history of the hot forging process of the manufacturing process of the gear, the steels were heated at 1523 K for 1.8 ks and cooled to the room temperature. Then they were heated at 1 198 K for 3.6 ks and cooled to the room temperature as a normalizing treatment. Columnar specimens for the carbu- Grade 20Cr Steel Composition, Properties, Material Dec 08, 2019 · Compared with 15Cr steel, 20Cr has higher strength and hardenability. The critical hardenable diameter in oil is 4-22mm, and the critical hardenable diameter in water is 11-40mm, but the toughness is poor. The machinability is good under high temperature normalizing or quenching and tempering conditions, but it is poor after annealing.
