Metlab is no ordinary heat treating company. Not only do we offer superior quality and reliability, we also have extraordinary capabilities in terms of size and quantity that enable us to serve domestic and international customers in diverse manufacturing operations. Metlab's unique and extensive equipment base offers customers the broadest available heat treating, surface treatment and size capability. As a result, customer designs are free from heat treating size constraints common in the industry. Processes offered include heat treating with protective atmosphere, carburizing, nitriding, and other thermal treatments, as well as black oxide surface treatments for protective corrosion and wear protection. We have a fully equipped laboratory on site for providing quality control, process certifications and metallurgical consulting.
