Common carbon quenched and tempered steel. The steel cold plastic in general, annealing, normalizing slightly better than quenched, high strength and good machinability, obtained by appropriate heat treatment after a certain toughness, ductility and wear resistance, material source convenience. Suitable for hydrogen bonding and welding, not well suited for welding. Preheating before welding, should be to stress annealing after welding. Normalizing improve hardness of less than 160HBS rough cutting. After the steel after quenching, its mechanical properties to be optimized for other carbon structural steel, but the steel hardenability is low, the water critical quenching diameter 12 ~ 17mm, has a tendency to crack when the water quenching. When the diameter is larger than 80mm, after quenching or normalizing, similar to the mechanical properties of the medium and small mold parts after quenching and tempering treatment can obtain higher strength and toughness, and large parts, places normalizing treatment is appropriate Therefore, this steel is usually used in the quenched and tempered or normalized state. # 4522605500 4.391 45 45 # 11020502600 Wugang Wugang 4.602 45 0.475 Wugang # 1102202500 # 1102402560 0.531 45 45 # 1102402200 Wugang Wugang 0.456 0.114 18 850 950 45 # 45 # Wugang 2024809650 3.757 45 Wugang Wugang 10.562 # 7523007800 2023305200 1.902 45 # 45 # 90197010000 Wugang Wugang 13.918 Henan Shen Chang Iron & Steel Co., Ltd. perennial spot stock more than 7000 tons.
