The decision to outsource the heat treatment work to Nitram was finally made at the beginning of this year, and has produced substantial savings.

Nitram offers a comprehensive advisory service backed by over 70 years of practical experience in a wide field of heat treatments.

The company's continuing investment ensures that equipment and technology are always at the cutting edge. The addition of an overpressure vacuum furnace was the first to be installed by the manufacturer in the UK.

In 1987 Nitram was one of the first companies of any type to gain ISO 9001 from BSI. Nitram also holds prestigious approvals from major aerospace companies and multinational manufacturers.

By using a vacuum, Nitram evacuates air and other residual gases from the chamber before and during the heating and holding periods, which gives a superior surface finish. Items are quenched in neutral gas or oil whilst still under vacuum. Treated items thus suffer less distortion and remain brighter than with traditional heat treatments.

Nitram is a family business giving a personal and individual attention and service with reliable and prompt turnarounds.
