Heat Treat Astm Sae 4340 Steel Round Bar Producer - China

4340 alloy steel is used to manufacture large and medium-sized plastic molds that require high strength and toughness.

And it is used for making important quality controlling parts with good toughness, high strength, and large size, such as heavy machinery and high load shafts, dia of turbine shafts is larger than 250mm, helicopter rotor shafts, turbojet turbine shafts, blades, high-load transmission parts, crankshaft fasteners, gears and etc.

After nitriding, it also can be used to make important parts for special performance requirements.

And it will be a great material for high strength and good plasticity parts after low-temperature tempering or isothermal quenching.

4340 steel is an ultra-high strength steel classified a medium-carbon, low-alloy steel.

4340 steel has high strength, ductility, toughness, creep resistance, and fatigue resistance relative to most other steels.

Hardness ranging from 24 to 53 HRC can be achieved, depending on the heat treatment.

4340 steel has high strength, toughness, wear resistance, and fatigue strength.

It can be machined in all states other than hardened and it is easily welded.

Additionally, 4340 can be cold worked easily in the annealed state.

This material is typically used in military aircraft, automotive systems, hydraulic parts, machine tools, and a steel crankshafts.
