45# steel is commonly used medium carbon quenched and tempered structural steel. The steel astm a283 black mild steel is generally cold plastic, annealing and normalizing are slightly better than quenching and tempering, with higher strength and better machinability. After proper heat treatment, 45# carbon steel can certain toughness, plasticity and wear resistance can be obtained. 45# steel normalizing can improve the cutting performance of roughness less than 160HBS.
astm a283 black mild steel, 15CrMo alloy steel is Chinese material. It is characterized by high Chrome and Molybdenum contents. The 15CrMo alloy steel chrome content is 0.80-1.10, and molybdenum content is 0.40-0.55. Besides, 15CrMo carbon content is 0.12-0.18, silicon content is 0.17-0.37, manganese content is 0.40-0.70. The heating temperatures for quenching and tempering of 15CrMo alloy steel are 900 and 650 centigrade respectively. The yield point of 15CrMo alloy steel is 295Mpa.
