Quenching is not necessary when hardening is done by Correct Answer Nitriding

Nitriding has a different hardening mechanism than the one caused by quenching a steel with an elevated level of carbon.
Instead, the hardening is caused by the fine scale precipitation of alloying element nitrides which does not require quenching.

Statement (I): Salts like sodium chloride, sodium hydroxide when added to water to use as quenching media, cooling rate of quenching media will be increased. Statement (II): When salts are added to water, during quenching, distortion and crack appearance in the quenched steel components reduces.
Consider the following statements: 1. The quenching of steel results in an increase in wear resistance, strength and hardness. 2. By the process of case hardening, hard wearing resistant surface is produced on mild steel. This is an effective method for low carbon steels because they cannot be hardened by the process of quenching. 3. When a metal is mixed with small atoms of non-metallic element in such a manner that invading atoms occupy interstitial positions in the metal lattice, an interstitial alloy results.
