Birchwood Technologies’ Tru Temp low-temp black oxide process is designed to created a non-dimensional finish, maintaining the same material hardness and load-bearing properties.

The Tru Temp blackening line operates at 200°F and forms a satin black magnetite finish said to protect critical surfaces in storage, shipment and startup, resists galling and aids in break-in.

The Tru Temp finish is Mil Spec and RoHS compliant, and withstands up to 120 hours of neutral salt spray or several hundred hours of humidity, verified by independent testing, the company says. The finish is a 0.5-microns-thick (20 millionths) crystalline structure that allows it to effectively hold a rust inhibitor and serves as a sacrificial barrier to provide break-in lubricity and galling resistance.

The operating solutions contain no EPA regulated chemicals and most process lines do not require waste treatment equipment. Tru Temp process lines are available in any size to fit parts and production volume.
