High-Performance Induction Hardening Solutions

Induction heating machines are used because they offer efficiency, fast heating, safety, cleanness, and accurate control. They are the fastest method for hardening and heat treating, resulting in minimal distortion and a fine-grain microstructure. Induction heating is accurate, fast, repeatable, and efficient, making it suitable for precise or repetitive operations. It is a rapid, energy-efficient, flameless method of heating electrically conductive materials.

For different workpiece materials, sizes and shapes, the frequency will be different accordingly.

Please send inquiry to us, we will recommend the optimal induction heating machine on your request.

We will recommend the most suitable cooling system based on different heating requirements.

Yes, you can prepare a water tank and a water pump to work as cooling system; Or you can directly prepare a cooling chiller.

Induction hardening is commonly used for mechanical parts that require improved durability, including:

• Shafts, gears, and camshafts
• Bearings, spindles, and axles
• Tools, springs, and stampings

The depth of hardening typically ranges from 0.5 mm to 8 mm, depending on the material, frequency, and heating duration. Deeper hardening is achievable for specific applications.

Yes, but it is less common. Non-ferrous materials like aluminum, copper, and nickel-based alloys can undergo induction heating for specialized purposes, though they don’t undergo the same martensitic transformation as steels.

Tempering is optional but recommended in many cases to reduce brittleness and achieve the desired balance of hardness and toughness.

Induction hardening is faster and more precise, suitable for localized treatment. Case hardening, in contrast, uses a combination of heat and chemical processes to diffuse carbon or nitrogen into the surface, typically for batch processing.

• Limited to materials with sufficient carbon or hardenability.
• Specialized equipment is required, increasing upfront costs.
• Best suited for parts with simple geometries.

Induction hardening can achieve surface hardness levels ranging from 37 to 65 HRC, depending on the material and process parameters.

Yes, induction hardening is adaptable to irregularly shaped parts. Custom-designed coils are used to ensure uniform heating and hardening of complex geometries.

Yes, induction hardening is energy-efficient and does not require harmful chemicals, making it an environmentally friendly heat treatment process compared to traditional methods.

Induction hardening causes minimal distortion due to localized and controlled heating. This makes it ideal for precision parts requiring tight dimensional tolerances.

The frequency of the alternating current affects the depth of hardening. Low frequencies penetrate deeper, while high frequencies focus on the surface. Selecting the right frequency ensures optimal results based on material and application.

The process introduces residual compressive stresses at the surface, countering tensile stresses that lead to fatigue failure. This improves the component’s resistance to repeated loading.

Induction hardening is faster and provides deeper hardening layers compared to nitriding. However, nitriding offers superior wear resistance and is suitable for parts that don’t require high-impact strength.
