These alloys are nitrogen-strengthened austenitic stainless steels exhibiting high strength with good toughness over a wide range of temperatures. Significant improvement in resistance to wear in particle-to- metal and metal-to-metal (galling) applications. Nitrogen alloying reduces the tendency for intergranular carbide precipitation in the weld area by inhibiting carbon diffusion and thereby increasing resistance to intergranular corrosion. Nitrogen alloying also improves resistance to pitting and crevice corrosion in aqueous chloride containing media. It exhibit improved resistance to trans granular stress corrosion cracking in hot aqueous chloride containing media. It is also suitable for welding dissimilar steels like mild steel and stainless steels, and also suitable for overlay on mild steel for corrosion and wear applications.
