What is 20CrMnMo?
20CrMnMo is a kind of alloy structural steel.
20CrMnMo is mainly used in the manufacture of mechanical parts that require high strength and toughness, such as automobile axles, gears, camshafts, connecting rods, etc. This steel has high strength, high toughness and good wear resistance. Its chemical composition mainly includes carbon (C), manganese (Mn), chromium (Cr), molybdenum (Mo) and iron (Fe) and other elements, the carbon content of 20CrMnMo is about 0.17% to 0.23%, manganese content between 0.90% and 1.20%, chromium content between 0.80% and 1.10%, and molybdenum content between 0.15% and 0.25%.The mechanical properties of 20CrMnMo include tensile strength greater than 980MPa, hardness of up to 280 to 320HBW, and at the same time good toughness and plasticity, this steel can be formed by different This steel can be formed by different heat treatment processes to meet different mechanical properties and wear resistance requirements.
In addition, the welding performance of 20CrMnMo is better, but it should be preheated properly before welding and tempered in time after welding.
