Abstract
Relative Härte, Reifegrad and stress released heat treatment and wear resisting properties of vanadium high-grade cast iron have been found to be superior to those of plain high-grade cast iron.
By the stress released heat treatment at 500°∼600°C for 6 hours, the vanadium cast iron acquires better mechanical properties than those of plain cast iron.
The vanadium cast iron is more resistive to abnormal abrasion caused by the increase of friction velocity.
