Product Description
DIN 30CrMoV9/1.7707 QT Alloy Structrural Steel Bar
1: 30CrMoV9 Steel Introduction
30CrMoV9 belongs to German standard nitriding steel, which is usually used to manufacture quenched and tempered parts, and is usually machined first and then nitrided. 30CrMoV9 is a steel commonly used in the manufacture of hardened and tempered parts, which are usually machined and subsequently nitrided. 30CrMoV9 alloy is usually produced by EAF/VD/LF, followed by electroslag refining (ESR), if specifically required.
