Annealing & Stress Relieving with Induction Heating

Enhance Metal Ductility, Stability, and Workability with Precise Thermal Processing

Induction annealing and stress relieving are essential heat treatment processes used to soften metals, improve ductility, and relieve residual stresses introduced during forming, machining, or welding. Unlike traditional furnace methods, induction heating provides rapid, localized, and highly controllable thermal processing — ideal for applications such as steel tubing, copper pipe, metal wire, and strip materials.

Why Use Induction for Annealing & Stress Relieving?

· Fast Throughput: Reaches target temperature in seconds — ideal for inline processes

· Accurate Temperature Control: Prevents overheating or grain growth

· Consistent Results: Ensures uniform microstructure and mechanical properties

· Energy Efficient: Heats only the part, not the surrounding air

· Scalable & Flexible: Suitable for batch or continuous production

Whether you're processing long coils of wire, copper tubing, or steel tubes, induction annealing offers a clean, fast, and repeatable solution.

Typical Applications

· Steel tube annealing after cold drawing

· Copper pipe annealing for HVAC and refrigeration

· Wire softening for electrical conductors or springs

· Brass and aluminum tubing for appliance manufacturing

· Stress relieving of weld seams in piping or automotive frames

· Edge annealing for strip steel or stainless materials

System Configurations for Industrial Annealing

Custom Coils & Process Integration

Each product geometry requires a unique coil design. We offer:

· Encircling coils for wire, tube, or rod

· Flat spiral coils for strip material edge annealing

· Multi-zone coils with progressive heating for long parts
