Tru Temp low temperature black oxide protects critical components used for drilling, production and refining petrochemicals and natural gas. For critical parts in storage or shipment, this low temp finishing process offers break-in lubricity, anti-galling protection and creates a protective barrier against corrosion.
This process is especially good for components manufactured to tight tolerances, yet doesn't affect function. Because of its crystalline structure, the Tru Temp finish has inherent break-in lubricity and galling resistance, thereby serving as a direct replacement for zinc phosphate finishes, but without the hazardous zinc content. This property makes it possible to operate the coating process without the need for hazardous waste treatment equipment.
The process operates at low temperature and contains no pollutants. Unlike other hot finishing methods, the Tru Temp process can be safely operated in-house for control over quality and turnaround time. Total process time is only 25 minutes, and operating cost in only 2 to 3 cents per pound of finished work. Components can be processed on racks or in bulk loads. Most existing tank lines can be retrofitted for Tru Temp at a low cost.
