42CrMo is a high-strength alloy steel widely used for manufacturing parts that must withstand high stress, impact, and wear. It is known for its excellent toughness, high fatigue resistance, and good hardenability.
Chemically, 42CrMo contains carbon (0.38–0.45%), chromium (0.90–1.20%), molybdenum (0.15–0.25%), and manganese. This alloy composition provides superior strength and mechanical durability. After quenching and tempering, the steel achieves very high performance.
42CrMo is delivered in hot-rolled, quenched and tempered, or normalization states depending on application requirements. Heat treatment significantly improves its strength and hardness.
Applications include shafts, gears, connecting rods, crankshafts, bolts, heavy-duty machine parts, and pressure vessels. Industries such as automotive, machinery manufacturing, and oil & gas highly favor 42CrMo for its reliability under extreme working conditions.
