BÖHLER V180

BÖHLER V180 VMR is a high-quality, low-alloy Ni-Cr-Mo-V steel with a high silicon and vanadium content, available in bars and forgings for components with a nominal cross-sectional thickness of up to 3.5 inches (89 mm) that require the highest strength and toughness values, especially for large cross-sections in the quenched and tempered condition.

This steel is typically used for parts that require a through-hardening steel with a minimum hardness of 53 HRC and can be used to produce finished parts that must meet the most stringent testing standards.

Due to the higher Si and V content of BÖHLER V180 VMR, this high-strength steel offers improved mechanical and fatigue properties compared to the standard 300M grade and is used for mechanically highly stressed parts with high fatigue loads, such as torsion bars, gears, and transmission shafts, primarily in racing and automotive engineering, but also in mechanical engineering. The dual vacuum melting process, using vacuum induction melting (VIM) and subsequent vacuum arc remelting (VAR), ensures a high degree of purity and homogeneity and also enhances the fatigue properties of the manufactured parts.
