Industrial Heat Treating Services — Metal & Foundries

Industrial heat treating is a controlled process of heating and cooling metal components to alter their physical and mechanical properties without changing their shape. Common objectives include increasing hardness, improving ductility, relieving residual stresses, and refining grain structure. Processes such as annealing, quenching, tempering, and case hardening are used across manufacturing, aerospace, petrochemical, and mining industries to extend component life and enhance performance.

Quenching involves rapidly cooling a heated metal—typically in water, oil, or air—to lock in hardness and strength. Annealing is the opposite: metal is heated and then cooled slowly in a controlled manner to soften the material, improve ductility, and relieve internal stresses. Quenching increases hardness for wear-resistant applications, while annealing is used to restore workability or prepare metal for further processing.

VaporKote processes a wide range of ferrous and non-ferrous metals, including carbon steels, alloy steels, stainless steels, tool steels, and select nickel- and cobalt-based alloys. Our team evaluates each material's composition to select the appropriate thermal cycle—ensuring the treatment achieves the desired metallurgical outcome without compromising base material integrity or dimensional tolerances.

Case hardening creates a hard, wear-resistant outer surface layer while leaving the core of the component tough and ductile—ideal for gears, shafts, and bearing surfaces. Through-hardening heats and quenches the entire cross-section, producing uniform hardness throughout. Case hardening is preferred when impact toughness is needed alongside surface wear resistance, while through-hardening suits applications requiring consistent hardness from surface to core.

VaporKote adheres to ASTM, ASME, SAE, and API engineering codes and practices for all heat treating operations. Our processes include rigorous temperature monitoring, cycle documentation, and metallurgical analysis to verify that treated components meet specified hardness, microstructure, and mechanical property requirements before they are returned to service.

Turnaround time depends on the process type, component size, and batch volume. Simple stress relieving or annealing cycles can often be completed within one to two business days, while multi-stage processes such as case hardening or IonPlasma Nitriding may require three to five business days. VaporKote works closely with clients to schedule treatments that minimize production downtime and meet project timelines.

Yes. VaporKote's state-of-the-art furnaces accommodate components up to 68 inches in diameter, making us well-equipped to handle oversized industrial parts common in petrochemical, mining, and heavy manufacturing applications. We also offer close-tolerance machining capabilities before and after heat treatment to ensure dimensional accuracy is maintained throughout the process.

VaporKote provides heat treating services to a broad range of industries including oil production and refining, petrochemical processing, aerospace, mining, agriculture, pulp and paper, heat exchanger manufacturing, and general industrial manufacturing. Our metallurgical expertise allows us to tailor thermal processes to the specific alloy compositions and performance requirements of each industry's critical components.
