Chrome-vanadium springs

Characteristics of Chrome-Vanadium Steel

Technical Specifications and Benefits for Industrial Applications

These steels function best after heat treatment and possess high strength, toughness, and resistance to wear and fatigue. In particular, vanadium improves the resistance to hydrogen cracking at high temperatures of the steel, and chromium and molybdenum offer high strength even at higher temperatures.
