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 corrosion resistance.
“We tried many ways to black oxide stainless steel but always fell short. But Birchwood got it right – it’s dynamite”, stated Steve D’Alfonzo, president of American Metaseal. “Zach Johnson at Birchwood is so helpful and got us going with the new Tru Temp Stainless black oxide and it has helped us pick up new customers.”
Operates at an optimum 200° – 210°F temperature range making it easy to use in-house and operator friendly. Other stainless black oxides operate at a much higher temp range between 250° – 260°F, making TRU TEMP® Stainless preferred finish as it never reaches boiling/splattering temp.
The most common finishing line configuration completes the blackening in under an hour in a seven-step process which includes: clean, rinse, activation, rinse, blackening, rinse, and sealing. Alternate process designs can be accommodated for most workflows.
