Question

Quizplus · Accepted Answer

Cyaniding is a type of case hardening process where the surface of the steel is hardened by introducing carbon and nitrogen into it, typically by immersing the steel in a molten cyanide salt bath. This process increases the surface hardness and wear resistance of the steel.
