PRODUCT APPLICATIONS

Induction Hardening of Engineering Machinery Parts

Induction hardening is a widely used surface heat treatment process that enhances the durability and wear resistance of engineering machinery parts. By using electromagnetic induction to heat the surface of metal components, followed by rapid cooling (quenching), this method creates a hardened layer that significantly improves fatigue strength and performance under heavy-duty conditions.

PRODUCT APPLICATIONS

Induction Hardening for Automotive Parts

Induction hardening is a highly efficient heat treatment process widely used in the automotive industry to improve the durability and performance of critical components. By rapidly heating and then quenching the surface of metal parts, induction hardening increases hardness, wear resistance, and fatigue strength without affecting the core properties of the material.

PROCESS INTRODUCTION

Induction Hardening Process

01
Induction Hardening Process

Induction hardening is a surface heat treatment process used to increase the wear resistance, surface hardness, and fatigue life of ferrous metal components by creating a hardened outer layer while maintaining a tough, unaffected core microstructure. This is achieved through rapid, localized heating of the component's surface using high-frequency alternating current in an induction coil, followed by rapid cooling (quenching).
02
Induction Heating

A copper coil carrying a high-frequency alternating current is placed near (but not touching) the steel component. This generates a strong, rapidly changing magnetic field. The alternating magnetic field induces eddy currents within the surface layer of the workpiece. The resistance to the flow of these eddy currents causes rapid and intense heating of the surface. Hysteresis losses in magnetic materials also contribute to the heating.
03
Hardening

Once the surface reaches the desired hardening temperature (above the austenitic transformation range), it is rapidly cooled using a quenching medium such as water, oil, brine, or air. This rapid cooling transforms the microstructure of the heated surface layer into martensite, which is very hard and brittle. The core of the component remains unaffected by this rapid heating and cooling cycle.
04
Tempering (Optional)

After hardening, the component may be tempered at a lower temperature to reduce brittleness and relieve internal stresses in the hardened layer, while still maintaining a high level of hardness.
