4135/4140/4142/6150 Alloy Coil EN10083-3 description

EN 10083-3 steel coil comprises various steel types including 50CrMo4, 51CrV4, 20MnB5, 34CrMo4, 42CrMo4, and 27MnCrB5-2, known for their high strength, toughness, and good hardenability. These alloys necessitate high-temperature preheating before welding to relieve stress after welding. EN 10083-3 steel coils are commonly used in the manufacturing of tools requiring good formability and high strength, often chosen for the production of large and critical components such as heavy-duty mechanical shafts, turbine shaft blades, high-load transmission parts, fasteners, crankshafts, gears, and heavy-duty parts of electric motor structures.
