1.	Nitriding is a process of hardening steel by treating it inan atmosphere ofA. `NH_(3)`B. `O_(3)`C. `N_(2)`D. `H_(2)S`
Answer» Correct Answer - A When steel is treated in the presence of `NH_(3)`, iron nitride on the surface of steel is formed which imparts a hard coating. This process is called nitriding.
