Metal Heat Treating Services in the Bay Area

Heat treating services involve controlled heating and cooling processes applied to metal components to alter their physical and mechanical properties—such as hardness, strength, ductility, and toughness. Common processes include annealing, quenching, tempering, case hardening, and stress relieving. These treatments help metals perform reliably under demanding industrial conditions, extending component service life significantly.

The four fundamental heat treatment processes are: (1) Annealing—heating and slow cooling to soften metal and relieve stress; (2) Hardening—rapid quenching after heating to increase hardness; (3) Tempering—reheating hardened metal to reduce brittleness; and (4) Case Hardening—treating only the surface layer to create a hard exterior while preserving a tough interior core.

The general term is simply 'heat treatment' or 'thermal processing.' Specific processes have distinct names: annealing, tempering, quenching, normalizing, and case hardening are the most common. Advanced surface treatments like boronizing, nitriding, and aluminizing are considered diffusion-based heat treating processes that introduce alloying elements into the metal surface at elevated temperatures.

VaporKote serves a broad range of industries including aerospace, oil production and petrochemical refining, mining, agriculture, pulp and paper, heat exchanger manufacturing, and general industrial manufacturing. Our heat treating solutions are engineered to address the specific wear, corrosion, and thermal challenges faced by each sector.

Conventional heat treatment modifies the bulk properties of metal through temperature cycles. Boronizing is a diffusion process that introduces boron atoms into the surface, forming an ultra-hard boride layer achieving RC75+ equivalency (1500 Knoop hardness)—harder than tungsten carbide. This makes boronized components exceptionally resistant to erosion, wear, and abrasion in the most demanding environments.

Turnaround times vary depending on the treatment type, component size, and required specifications. Simple stress relieving or annealing cycles may be completed within 24–48 hours, while advanced diffusion treatments like boronizing or IonPlasma nitriding may require several days. We work closely with clients to establish realistic timelines that minimize operational downtime.

Yes. VaporKote adheres to ASTM, ASME, SAE, and API engineering codes and practices, and provides metallurgical analysis and certification of diffusion coatings. Each treated component undergoes thorough quality verification—including hardness testing and diffusion depth analysis—ensuring documented compliance with your project's technical and industry-specific requirements.

Absolutely. VaporKote operates state-of-the-art furnaces capable of processing large components up to 68 inches in diameter. Whether you need heat treatment for compact precision parts or oversized industrial equipment used in Bay Area refineries or manufacturing plants, our facility is equipped to handle the job with consistent, high-quality results.
