Chromium Vanadium Springs

Chromium vanadium is a popular type of steel made by alloying chromium, carbon, vanadium, and other metals. SMSC provides chromium vanadium springs for various industrial applications. These springs offer benefits of specific load tolerances, hardness, corrosion resistance, and stress-reliever characteristics due to their typical chemical composition. Hence, these steel springs are employed for high impact load, and high stress applications. Also, these steel springs will perform well in extreme temperatures.

Key Features of Chromium Vanadium Alloy

Following are some of the key features of Cr-V alloy:

  • The alloy is structurally strong, which makes it wear, and fatigue resistant.
  • The minimum tensile strength is 190 – 300 depending on the chemical composition. This is high in comparison to other alloys.
  • The maximum operating temperature of the alloy is 425℉ (218℃).
