DIN 1.6580 30CrNiMo8 Alloy Steel
Description
30CrNiMo8 Alloy Steel- Quenching and tempering steel with a very high hardenability.
30CrNiMo8 Steel is a heat treatable steel which has at least 1.8%Cr,1.8%Ni, and 0.3%M0 as strengthening alloy elements. It is usually supplied with quenched and tempered condition with a typical tensile strength of 1100 -1300 N/mm².
Used for highly stressed components, where the combination of high strength with tenaciousness is of utmost importance.
