Product Description
DIN 17200 30CrMoV9/1.7707 Alloy Steel Bar
1: 30CrMoV9 Steel Introduction
30CrMoV9 is a medium-carbon Cr-Mo-V alloy structural steel with excellent strength, hardenability, toughness, and minimal quenching distortion. Typically supplied in quenched and tempered condition (28-32 HRC), it is widely used in critical components such as shafts, gears, fasteners, and hydraulic parts. The addition of vanadium enhances grain refinement, fatigue resistance, and high-temperature strength, making it suitable for dynamic loads and moderate-temperature environments.
