9310 Steel

What is 9310 Steel? Understanding the Composition and Properties

9310 steel is a nickel-chromium-molybdenum alloy engineered for exceptional strength, toughness, and wear resistance. Known for its high hardenability and fatigue strength, 9310 round bar is widely used in demanding applications that require durability across large cross-sections and high-stress environments.

Chemical Composition of 9310 Steel

The balanced alloying elements of 9310 steel contribute to its superior mechanical performance:

  • Carbon: 0.08 – 0.13%
  • Manganese: 0.45 – 0.65%
  • Phosphorus: 0.025% max
  • Sulfur: 0.025% max
  • Silicon: 0.20 – 0.35%
  • Nickel: 3.0 – 3.5%

This combination results in excellent core strength, hardness, and machinability, making it a highly reliable alloy for critical components.
