Annealing for critical industrial components in Chennai.

Annealing softens steel so it can be machined or formed with less tool wear and less risk of cracking. We provide soft, sub-critical, spheroidise, and isothermal annealing for bars and coils serving the automobile industry, with uniform heating and controlled cooling that holds results consistent from batch to batch across a 30-ton-per-batch capacity.

Typical Applications

  • Bars and coils for the automobile industry
  • Steel castings requiring softening before machining
  • Components needing improved formability
  • Parts requiring relief of internal stress

Why Annealing Matters

01

Lower hardness

Softened steel machines and forms cleanly with reduced tool wear.

02

Improved formability

A ductile structure lets components be shaped without cracking.

03

Batch consistency

Uniform heating and cooling deliver repeatable results across every load.

The Heat-Treatment Cycle

A schematic of the annealing cycle: a controlled ramp to temperature, a soak to equalise the section, then the cooling stage that defines the result.
