42CrMo Round Bar
42CrMo Round Bar Products Description
The chemical composition of 42CrMo round steel includes carbon (C), silicon (Si), manganese (Mn), sulfur (S), phosphorus (P), chromium (Cr) and molybdenum (Mo) and other elements. Among them, the carbon content of 0.38% to 0.45%, chromium content of 0.90% to 1.20%, molybdenum content of 0.15% to 0.25%.
The main characteristics of 42CrMo round steel include high strength, high toughness and good NMenability. At room temperature, its tensile strength can reach 1930MPa, yield point of 1270MPa, elongation and section shrinkage of 12% and 40%, respectively, these characteristics make 42CrMo round steel in withstand heavy loads and high-intensity working conditions outstanding performance. In addition, 42CrMo round steel also has good NMenability and fatigue resistance, after tempering treatment, has a high fatigue limit and resistance to multiple impacts, low temperature impact toughness is good.
42CrMo Round Bar Products Applications
42CrMo round steel has a wide range of applications, mainly used in the manufacture of various machines to withstand impact, bending and torsion, high loads in the important parts, such as rolling mill herringbone gears, crankshafts, hammer rods, connecting rods, fasteners, turbine engine spindles, axles, engine transmission parts, large motor shafts, etc. 2. In addition, 42CrMo round steel is also suitable for the manufacture of large and medium-sized plastic molds that require a certain degree of strength and toughness. 42CrMo round steel is also suitable for the manufacture of large and medium-sized plastic molds requiring certain strength and toughness.
