DIN 1.7035 / 41CR4 Steel is one of the most widely used alloy steel.After QT heat treatment,41CR4 steel has good comprehensive mechanical properties,low temperature impact toughness and hardenability.DIN 1.7035 steel can get higher fatigue strength after oil cooling.41Cr4 structural alloy steel is used for mechanical parts and all kinds of engineering components and contains one or several kinds of alloy element in steel.
41CR4 Alloy structural steel is widely used in ships,vehicles,aircraft,missiles,weapons,railways,Bridges,pressure vessels and so on.

The machinability of 41Cr4 steel is good for normalizing and QT condition.But the weldability of 1.7035 alloy steel is not so good that it's easy to produce cracks.This material requires preheating before welding.more details you can get if you contact us.
