Bluewater’s carbon restoration heat treatments are applied to steel parts in order to correct the surface decarburization that occurs from high temperature metalworking processes performed in air, such as investment casting and hot forging. This heat treatment is performed in carbon-controlled atmosphere batch furnaces. Carbon restoration cycles use carbon potential controlled furnace atmospheres to re-establish the correct carbon content on the surface of the steel part. Carbon restoration is normally applied to alloy steel forgings or castings intended for applications with critical mechanical performance requirements that must retain a uniform structure over the entire surface of a part.

Induction Hardening is a form of heat treatment Bluewater utilizes to selectively harden a metal part or component via means of a solid state RF power supply that sends currents through an inductor coil which then transmits electromagnetic waves that heat the metal parts or components. Induction hardening occurs because the parts placed inside the inductor coil have entered a magnetic field and the eddy currents from that field are introduced to the surface layer of the part through electrical resistivity. The natural electrical resistance of the metal within the coil causes the currents to flow against the part, which then generates accurate and focused heat.
