Carbonitriding of four types of steels, namely, low carbon steel (LCS), medium carbon steel (MCS), low alloy steel (LAS) and high alloy steel (HAS) was achieved using cyanide salt bath heat treatment process. The steels, after preheating, were heated in a diesel fired salt bath heat treatment furnace and then quickly quenched in different media including air, oil and brine. The heat treatment p...

AISI 304 stainless steel categorized under austenitic, has good resistance to corrosion and applicable for high pitting stresses. But it poor hardness, sterngth wear. In order overcome the above problem, various hardening techniques like nitriding, carburizing, carbonitriding, Cyaniding etc are preferred. this work, aqueous soluted nitriding process is carried out improve surface hardness wear ...
