4135/4140/4142/6150 Alloy Coil EN10083-3 Description
There are steel types 50CrMo4, 51CrV4, 20MnB5, 34CrMo4, 42CrMo4, and 27MnCrB5-2. EN 10083-3 steel coil has high strength, high toughness and good hardenability. This alloy requires high-temperature preheating before welding to relieve stress after welding. EN 10083-3 steel coils are used in the manufacture of tools that require good formability and high strength. It is usually chosen to manufacture large and important parts, such as heavy-duty mechanical shafts, turbine shaft blades, high-load transmission parts, fasteners, crankshafts, gears, and heavy-duty parts of electric motor structures, etc..
