60-62 HRC Martensitic wear-resistant alloy, NT Fe-CrV15, with a high content of vanadium carbide, specially developed for weld surfacing of components subject to abrasive wear; also corrosion-resistant by virtue of the free Cr content of more than 13 %; moreover, capable of secondary hardening in the range from 500 °C to 550 °C; decrease in hardness beyond the latter temperature, but maximal retention of wear resistance because of the carbide content PTA
