Corrosion Resistance

Corrosion Resistance Evaluation

The salt bath nitriding process consist of preheating, nitriding, quenching and water rinses. A supplemental process known as QUENCH - POLISH - QUENCH is offered by Houston Unlimited, Inc. This process involves ferrous components that have been salt bath nitrited.

The parts are then mechanically polished to achieve a comparable original finish, reimmersed into the salt quench bath, water rinsed and oiled. The product of this QUENCH - POLISH - QUENCH process is a layer of iron oxide on the surface that enhances the corrosion resistance for non- stainless steels and promotes an appealing, black, cosmetic finish.
