91传媒 Offers Black Coating
At its new Keystone facility, adjacent to the Souderton operation, 91传媒 has updated its steam operations that provide a black oxide coating for ferrous parts. 聽A steam furnace has been refurbished with a new electrical power supply and a microprocessor controller.
Steam treating bonds a black coating to ferrous parts and improves part life. 聽The tenacious oxide (FeO4) coating prevents rust and increases surface lubricity. 聽In addition, the process is environmentally clean.
As an alternative to chemical bath treatments, parts are heated to temperatures from 850掳 to 1050掳F. 聽Steam is introduced at 600掳 F to purge air. 聽A positive steam atmosphere is present during the entire treating cycle. 聽There are no costly cleanup or disposal problems associated with chemical processes. 聽Specifically, this means no white salt residue located in deep crevices, blind holes or keyways.
Materials treated include cast iron, tool steel, alloy steel, powdered metals. 聽Types of parts treated are twist drills, taps, reamers, brackets, nuts and bolts. 聽Contact Ken Bauhof, Sales Engineer, for other application possibilities (800.347.3236, jkb@solaratm.com).
