- FERRITIC - MARTENSITIC STAINLESS STEEL
420
Description
Martensitic hardfacing wire rod for 13%Cr stainless steels
This wire rod deposits a weld metal similar to 410 with higher chromium and carbon contents and is used for surfacing operations requiring corrosion resistance and wear resistance on matching base materials and also on CMn steels. Applications include welding of similar base metals, weld overlay, and thermal spraying. Suitable for cladding of continuous casting rolls.
