Our Heat Treatment Services

1. Carbon Case Hardening (Carburizing) Carbon case hardening, or carburizing, is a heat treatment process used to harden the surface of steel components while maintaining a tough and ductile core. This process is ideal for components subjected to high wear and stress, such as gears, shafts, and bearings. The outer surface becomes hard and wear-resistant, while the inner core retains toughness and resistance to impact.

Applications:

• Gears (e.g., automotive transmission gears, industrial gearboxes)

• Shafts (e.g., drive shafts, crankshafts)

• Bearings (e.g., roller bearings, needle bearings)

Benefits:

• Increased wear resistance on the surface.

• Retained toughness and flexibility in the core.

• Improved fatigue strength.

2. Nitrogen Hardening (Nitriding) Nitrogen hardening or nitriding is a process where nitrogen is diffused into the surface of steel components, creating a hard, wear-resistant surface. This heat treatment method is often used for high-strength, high-durability parts, as it significantly enhances surface hardness and corrosion resistance. Nitrogen hardening is ideal for parts exposed to friction and harsh environments, such as gears, shafts, and valves.

Applications:

• Gears (e.g., high-performance gears in automotive or aerospace industries)

• Engine parts (e.g., camshafts, valve stems)

• Hydraulic components (e.g., hydraulic cylinders, pistons)

• Tooling and dies (e.g., dies used in metal forming)

Benefits:

• Improved wear and corrosion resistance.

• Increased surface hardness without compromising core toughness.

• Enhanced fatigue strength and reliability.

3. Induction Hardening Induction hardening is a localized heat treatment process that uses induction heating to selectively heat the surface of a component. The part is then rapidly cooled (quenched), resulting in a hard surface with a tough interior. This technique is typically used for high-stress parts like shafts, gears, and crankshafts that need localized hardness in areas subject to wear or fatigue.

Applications:

• Crankshafts and camshafts for automotive and industrial engines.

• Gears (e.g., pinion gears, planetary gears in transmissions).

• Shafts (e.g., driveshafts, axles).

Benefits:

• Selective hardening, allowing targeted strengthening of high-stress areas.

• High-speed process with minimal distortion.

• Excellent wear and fatigue resistance.

4. Annealing Annealing is a heat treatment process that involves heating a material to a specific temperature and then slowly cooling it to relieve internal stresses, improve ductility, and refine the grain structure. This process is essential for materials that need to be easily machined or formed into complex shapes after forging. Annealed parts have better workability, reduced brittleness, and enhanced toughness.

Applications:

• Shafts, rings, and discs that require enhanced machinability.

• Forged components for aerospace, automotive, and heavy machinery industries.

• Forging dies and molds used in manufacturing.

Benefits:

• Improved machinability.

• Reduced brittleness and internal stresses.

• Increased ductility and toughness.

5. Quenching and Tempering Quenching and tempering is a two-step heat treatment process used to enhance the hardness, strength, and toughness of steel. During quenching, the component is heated to a high temperature and then rapidly cooled in a quenching medium (e.g., water or oil). In the tempering step, the component is reheated to a lower temperature to adjust its hardness and relieve internal stresses.

Applications:

• Forged components in automotive (e.g., suspension parts, axles, gears) and heavy machinery (e.g., parts for mining and construction equipment).

• Valve bodies and flanges for the oil & gas industry.

• Fasteners and bolts used in high-stress environments.

Benefits:

• Achieves a balance of hardness and toughness.

• Improved strength and fatigue resistance.

• Enhanced wear and impact resistance.

6. Stress Relieving Stress relieving is a heat treatment process that reduces internal stresses in forged components, which can result from the forging process or subsequent machining. By heating the material to a specific temperature and allowing it to cool slowly, this process improves the dimensional stability and reduces the risk of warping, cracking, or failure during service.

Applications:

• Large forged components like machine frames and structural parts.

• Heat-treated parts that have been hardened or quenched.

• Tooling and dies that need to maintain dimensional accuracy.

Benefits:

• Reduces residual stresses from forging or machining.

• Improves dimensional stability and reduces the likelihood of distortion.

• Increases the material’s ability to withstand future stress and load.

7. Vacuum Heat Treatment Vacuum heat treatment is a specialized process that takes place in a vacuum chamber to prevent oxidation and contamination of the material. This process is particularly beneficial for high-value or sensitive parts where surface cleanliness and uniformity are crucial, such as aerospace components, medical devices, and high-precision tooling.

Applications:

• Aerospace parts (e.g., turbine components, critical fasteners).

• Medical devices (e.g., surgical tools, implants).

• High-precision components (e.g., gears, shafts, and dies).

Benefits:

• Elimination of oxidation and contamination.

• Enhanced surface finish and cleanliness.

• Improved material properties with high precision.
