Din 1 6511 Aisi 4340 Steel Price Per Kg Producer - China

4340 steel is nickel-chromium-molybdenu m alloy steel.

It will get high strength after the heat treat.

And it has good toughness, fatigue resistance, impact toughness and etc.

Its equivalent grade is JIS SNCM439 and DIN 1.6511 / DIN 1.6582 - The properties and composition of 4340 steel round bar sheet plate as below.

It is an alloy structural grade which used by the SAE International(SAE), and it is chrome-nickel low alloy steel.

4340 steel round bar sheet plate will get high tensile strength, hardness and toughness after heat treatment.

It is used widely in the transmission components of heavy chemical machinery.

Different sections of each part of the casting which cause the temperature difference stress and phase transformation stress.

If you can’t get their laws and characteristics, you can’t take the right rational processes.

The consequence is that there is a risk of cracking the casting during the casting or heat treatment.

So the control of chemical composition and the choice of the heat treatment process for the casting are really important.

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.

We have our own cutting and processing equipment.

Specifications can be cut and customized according to your requirements.
