Webprocesses between gas soft-nitriding and gas carburizing on mechanical properties of various steel e.g., AISI 1010, 1020, 1040, 4140 and 4340. The specimen was normalized by normalizing and shot blasting. Gas soft-nitriding, gas carburizing, gas carbonitriding and the combined processes were employed to treat the specimen. WebNitriding. Nitriding is a surface-hardening heat treatment that introduces nitrogen into the surface of steel at a temperature range (500 to 550°C or 930 to 1020°F), while it is in the ferrite condition. Thus, nitriding is similar to carburizing in that surface composition is altered, but different in that nitrogen is added into ferrite ...
