Utilizing a unique two-stage oxidation (Patented), the Tru Temp® Mid-Temperature Black Oxide forms a black magnetite finish on all iron and non-stainless steel parts. The Tru Temp process operates effectively at much lower temperatures than hot black oxide – 100 degrees lower, in fact! The result is a protective black finish - 0.000020" (1 micron) thick, with an attractive satin black appearance equal to that of hot black oxide.
Introducing the new patent pending TRU TEMP® 2ND GEN mid-temperature black oxide. An industry first mid-temperature black oxide with capabilities to finish a wide range of ferrous metals including iron, steel and tool steel, all with one black oxide formulation. LEARN MORE
