Characteristics of Chrome-Vanadium Steel
Technical Specifications and Benefits for Industrial Applications
These types of steel perform 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 in the steel, and chromium and molybdenum offer high strength even at elevated temperatures.
