welding-alloys.com 31 Ferritic & martensitic stainless steels Martensitic stainless steel deposits with over 12% Cr offer good resistance to thermal fatigue and corrosion. These grades are ideal for applications where there is hot metal-to-metal wear. Martensitic stainless steels are widely used in steelmaking and forging for casting, rolling and forming operations. The addition of elements such as nitrogen, vanadium, tungsten or even cobalt increase the resistance of these alloys to high temperatures and corrosion.

The safety datasheets are also available on request. When surfacing a low or medium alloyed base metal with martensitic stainless steels, it is advantageous to apply a special buffer layer, which is overalloyed in chromium (~ 17% Cr), to guarantee metallurgical soundness and to avoid cracking in service.
