Neutral Hardening & Austempering Manufacturers

Neutral Hardening & Austempering consists of processing parts in an atmosphere which will neither enrich nor deplete the surface of carbon. Heat treating done in an oxygen-free environment that is chemically neutral to the surface of the steel. Endothermic atmosphere or nitrogen blankets are used. Austempering is a special form of heat treating in which the work is quenched in hot salt, the transformation is complete at the quenching temperature and no tempering treatment is required. Austempering is limited to thin section, plain carbon steel and to the lower alloy steels, it also offers several potent ion advantages.
