High Plasticity Good Ductility Heat Treating 4340 Structural Steel Alloy Din 36crnimo4 Product - China

4340 is a high-strength alloy steel grade in American Standard ASTM A322 - 4340 is mainly used to manufacture important parts with high strength and good plasticity.

After nitriding treatment, it can manufacture important parts with special functional requirements, such as shafts, gears, fasteners, etc.

German DIN steel number 36CrNiMo4, German DIN material number 1.6511, French NF standard 40NCD3, Japanese JIS standard SNCM439, British BS standard 816M40, American AISI/ASTM4340, American UNS standard G43400 It has high strength, toughness and excellent hardenability and stability against overheating, but has high white point sensitivity and temper brittleness.

The weldability is poor.

It needs to be preheated at high temperature before welding, and the stress needs to be relieved after welding, and it is used after quenching and tempering.

4340 steel is a medium carbon nickel chromium molybdenum steel alloy with excellent tensile strength, toughness and fatigue resistance.

Since the material is usually in the annealed state, additional heat treatment can produce parts with higher strength and fatigue resistance.

In addition, 4340 steel is a wear-resistant material with particularly good wear, impact and impact resistance, as well as excellent atmospheric corrosion resistance.
