TWO STRENGTHENING MECHANISMS

The two key strengthening mechanisms accounting for high yield strengths in low-alloy steels are:

Their effect in a typical high-strength steel is shown below:

Nitrovan® vanadium enhances precipitation strengthening and grain refinement—two mechanisms that provide up to 70% of the yield strength of a typical high-strength, low-alloy steel.

Grain refinement is the only mechanism that improves both strength and toughness while reducing the embrittling effects of precipitation. By balancing grain refinement and precipitation hardening, good toughness is obtained in high-strength steels.
