EN10083-3 34CrNiMo6 Alloy Steel Plate Heat Treatment

34CrNiMo6 alloy steel plate has high strength, because of its excellent comprehensive mechanical properties.EN10083-3 34CrNiMo6 is widely used in the manufacture of the engine camshaft and connecting rod and other important parts. But 34CrNiMo6 has poor processing, and it is a typical difficult to process material.

EN10083-3 34CrNiMo6 Chemical Composition:

C: 0.34
Si: 0.25~0.30
Mn: 0.5
Mo: 0.2
Cr: 1.5
Ni: 1.55

Mechanical Property of 34CrNiMo6 Alloy Steel Plate

After quenching and tempering treatment, the Hardness of 34CrNiMo6 material is 36 ~ 40HRC；The Tensile strength σb of 34CrNiMo6 material is 1 100 MPa,；The Elongation δ of 34CrNiMo6 material is 12%,；The Impact toughness value ακ of 34CrNiMo6 material is 8kg / cm2.

34CrNiMo6 Alloy Steel Classification:

1, quenched and tempered structural steel

The amount of carbon in this type of steel is generally about 0.25% to 0.55%. For structural sections of a given cross-section size, mechanical properties such as quenching and tempering during quenching and tempering (quenching and tempering) are good. If the quenching is past, microstructure appears free ferrite, the toughness decreased.

2, surface hardening structural steel

Surface hardened structural steel is used to make the surface hard and flexible parts of the heart, such as gears, shaft and so on. In order to make the parts of the heart of high toughness, the steel carbon content should be low, and generally is 0.12 ~ 0.25%, while the amount of alloying elements to ensure the appropriate hardenability.
