The cladding metal of the Lron-based Alloy Cored Wire Rock 250 metal core gas shielded welding wire, designed for anti-cavitation, corrosion-resistantand erosion-resistant overlay welding, is a nitrogen-enhanced austenitic stainless steel with outstanding cavitationresistance comparable to that of cobalt-based alloys. It exhibits a high strain hardening rate, enabling the formation ofHard surface layer under cavitation conditions. This hard layer, combined with the softer base material, effectively absorbscavitation stresses and significantly reduces damage rates.
