Heat Treatment Services
Heat treatment is where a forging's mechanical properties are actually decided. We run annealing, normalising, hardening, quenching and tempering cycles with logged furnace charts, then verify results by hardness testing and, where specified, tensile and impact testing.

Quotable facts from Avadh Techno Forge, Gundasara, Gondal, Rajkot.
- Processes: Anneal, normalise, harden, temper, stress relieve

The Cycles We Run
Full annealing softens for machining; normalising refines grain and evens out forging variation; hardening and tempering set final strength and toughness; stress relieving removes residual stress before finish machining. The cycle is chosen from the grade and the property target, not from habit.
- Annealing and spheroidise annealing
- Normalising for grain refinement
- Hardening with oil or polymer quench
- Tempering and stress relieving
Recorded, Repeatable, Auditable
Every charge carries a chart showing soak temperature, soak time and quench medium against the batch number. When a customer audits a shipment two years later, the thermal history of that exact batch is retrievable — a requirement under both ISO 9001 and IATF 16949.
Verification, Not Assumption
Hardness is checked on Brinell and Rockwell testers across the section, not just at one convenient corner. Where the specification calls for it, we section a sample for microstructure examination and tensile testing so the certificate reflects measurement rather than expectation.
People also ask
Is heat treatment done in-house or outsourced?
In-house, with furnace charts recorded per batch and hardness verified before release, which keeps the thermal history inside our own traceability system.
Can you hold a specific hardness band?
Yes. Tempering temperature is set for the grade and section to land inside your specified band, with results reported per batch.

Questions Answered
Is heat treatment done in-house?
+
Yes, which removes transport time and the risk of mixed batches at an outside vendor, and keeps the thermal record inside our own traceability system.
Which forgings need normalising?
+
Most carbon and alloy steel forgings that will be machined or must meet a specified grain size. Normalising evens out the variation left by different cooling rates across a forged section.
Can you meet a specific hardness range?
+
Yes. Tell us the target band in BHN or HRC and the tempering temperature is set to land inside it, with results reported per batch.
Do you offer case hardening?
+
Case carburising and carbo-nitriding are arranged for parts that require a hard case with a tough core, with process records supplied.
