Nitriding is a heat treating process used for producig a very hard case (Vickers 1100) and is typically used to produce hard, strong, tough steels. The process involves heating heating the steel to 500-540°C (930-1000°F) in an atmosphere of ammonia gas for about 50 hours. No further quenching or heat treatment is required. The case depth is about 0.4 mm. Nitrided surfaces also can improve corrsosion resistance.
