Induction Hardening

" Improve wear resistance and extend component service life "

Applications...

Induction hardening is used across a wide range of industrial sectors due to its ability to significantly improve the mechanical properties of metallic components.The main application areas include :

Automotive industry

Components such as shafts, gears, transmission shafts,and other critical parts that require high wear resistance and fatigue strength.

Tooling and Die Industry

Cutting tools and dies, where surface hardness is essential for extending tool service life.

Heavy Machinery Industry

Components used in large machines and equipment that are subject to constant wear and require high durability.

Steel Selection

Carbon Content: Higher carbon content leads to greater hardness after hardening, but it can also increase the risk of cracking or distortion.Generally, a carbon content between 0.4% and 0.6% is ideal for induction hardening.

Alloy Composition: Manganese helps increase hardening depth, while chromium can improve corrosion resistance, and boron can enhance hardenability.

Microstructure: Steels with a fine and uniform grain structure are generally easier to harden without cracking or distortion.

Advantages of Localized Hardening

Surface hardening is concentrated on the component surface, while the core retains tougher and more resilient properties, providing an ideal combination of hardness and fatigue resistance.

Reduced Distortion: Due to its localized and rapid heating process, induction hardening tends to cause less distortion of the component when compared to other surface heat treatment methods.
