42CrMo is an alloyed structural steel, also known as ultra-high strength steel. This steel has attracted much attention because of its high strength, high toughness and good hardenability.
42CrMo steel plate features:
High strength and toughness: 42CrMo steel has excellent strength and toughness, and can withstand large loads and shocks.
Good hardenability: This steel has good hardenability, small deformation during quenching, and a uniform hardness and strength distribution can be obtained.
No obvious tempering brittleness: After tempering treatment, 42CrMo steel has a high fatigue limit and multiple impact resistance, and good low temperature impact toughness.
High temperature performance: At high temperatures, 42CrMo steel can still maintain high creep strength and durable strength.
The chemical composition of 42CrMo steel mainly includes carbon (C) 0.38~0.45%, silicon (Si) 0.17~0.37%, manganese (Mn) 0.50~0.80%, sulfur (S) and phosphorus (P) allowable residual content ≤0.035%, chromium (Cr) 0.90~1.20%, molybdenum (Mo) 0.15~0.25%. In addition, the allowable residual content of nickel (Ni) and copper (Cu) is ≤0.030%.
The delivery status of 42CrMo steel plate is usually conditioned, which is to improve the comprehensive mechanical properties of the steel plate. The melting analysis and delivery status need to be strictly controlled to ensure the chemical composition of the steel plate is stable and the mechanical properties are excellent.
42CrMo steel is widely used in many fields because of its excellent properties. It is often used in the manufacture of large and medium-sized plastic molds requiring certain strength and toughness. In addition, it is also used in the manufacture of various mechanical parts, such as gears, crankshafts, bearings, etc., as well as for the manufacture of various construction machinery, automotive parts, heavy machinery, metallurgical machinery, petroleum machinery and mining machinery. 42CrMo steel also plays an important role in the fields of high-speed cutting machine tools, oil mining machinery, construction machinery and mining equipment.
