The new TRU TEMP® Stainless black oxide finishing process is used as part of a two-stage chemical reaction, beginning with an activation step with a dilute muriatic acid solution. The stainless-steel surface is then oxidized to form the uniform black coating that can be sealed with an appropriate rust preventive topcoat for optimum appearance and […]

TRU TEMP® 2nd GEN generates a darker and cleaner black oxide finish on an expanded range of high-alloy and high-strength steels and iron. The magnetite finish is non-dimensional at 1 micron thick and ideal for machined components, non-machined components, powdered metals, MIM parts, tooling, gears, sucker rods and more.
