Heat Treatment Service

Heat treatment improves the mechanical properties of metal parts by enhancing strength, hardness, and wear resistance. It ensures better performance and durability for components used in demanding applications.

Service Overview

At CMS, our heat treatment service is designed to improve the mechanical properties, wear resistance, and durability of metal parts. With over a decade of experience in precision manufacturing, we provide tailored heat treatment solutions to meet the requirements of various industries.

Our processes include:

  • Annealing – Relieve internal stresses and soften metals for easier machining.

  • Quenching – Rapid cooling to increase hardness and strength.

  • Tempering – Reduce brittleness after quenching while maintaining hardness.

  • Normalizing – Refine grain structure for improved toughness and dimensional stability.

  • Surface Hardening – Enhance wear resistance of critical components, including carburizing, nitriding, and induction hardening.

We combine advanced equipment with skilled engineers to ensure consistent results and precise control of material properties, suitable for both prototype and mass production runs.

What Is Heat Treatment?

Heat treatment is a controlled process of heating and cooling metals to alter their mechanical and physical properties without changing the chemical composition.

Benefits include:

  • Increased hardness and wear resistance

  • Improved toughness and impact strength

  • Reduced internal stresses and distortion

  • Enhanced machinability and surface finish

  • Extended service life of components

Heat treatment is commonly applied to steel, stainless steel, aluminum alloys, and copper alloys, making it essential in automotive, aerospace, industrial machinery, and tooling industries.

Heat treatment is a controlled heating and cooling process used to improve material properties such as hardness, strength, toughness, and wear resistance.

Most carbon steels, alloy steels, tool steels, and some stainless steels can be heat treated. Aluminum and titanium alloys can also be aged or stress-relieved.

CMS supports:

  • Hardening & Quenching

  • Tempering

  • Normalizing

  • Annealing

  • Stress-Relief

  • Aging (Aluminum/Titanium)

Yes. Heat treatment may cause slight distortion or size change. CMS evaluates critical areas and may apply pre-compensation machining.

Depending on material and process, hardness can increase significantly — e.g., carbon steel may reach HRC 55–62 after quenching and tempering.

It depends on the part:

  • Hardening is usually done before final machining (followed by grinding).

  • Stress relief is often done before rough machining.

  • Aging may occur at the end for aluminum.

Yes, but hard materials require grinding or specialized tooling. For very hard surfaces, post-machining may be limited.

Yes. Steel often darkens or oxidizes after heat treatment. Additional finishing (polishing, coating, grinding) can restore appearance.

Yes, but requires careful process control. CMS ensures temperature uniformity and minimized deformation for precision applications.

Usually 2–5 days, depending on material, hardness requirements, and batch size.
