The Importance of Nitrogen in the Heat Treating of Ferrous and Non-Ferrous Metals and Alloys

Abstract

Nitrogen was first used as the base gas for treating and annealing semifinished products of steel. Since then the use of industrial gases has spread to cover the full range of heat treatment processes for ferrous and non-ferrous metals and alloys. This paper is focused on titanium and titanium alloys nitriding but also on the recommended nitrogen process atmosphere for ferrous and non-ferrous metals and alloys.
