Heat Treatment
Section
19 furnaces spanning induction hardening, carburising, nitriding, tempering, and controlled atmosphere processes — transforming component metallurgy for superior hardness, fatigue resistance, and service life since 1973.
Altering Metallurgy for Lasting Performance
Heat treatment is a critical process in metallurgy and material science that alters the physical and sometimes chemical properties of a material to enhance its performance and durability. Through controlled heating and cooling, Pivot Fabrique's Heat Treatment Section transforms component microstructure — delivering superior hardness, wear resistance, toughness, and fatigue life. All 19 furnaces operate in-house under ISO/TS 16949:2009 quality control, with full traceability on every batch.
Surface Hardening
Induction hardening and nitriding deliver precise surface hardness without compromising core toughness.
Case Carburising
Controlled carbon diffusion for deep case depth — ideal for gears, shafts, and transmission components.
Stress Relieving
Tempering and shaker hearth cycles relieve residual stress and stabilise component dimensions post-hardening.
Atmosphere Control
Reducing and endothermic atmosphere furnaces prevent oxidation and decarburisation throughout the cycle.
Complete Heat Treatment Machine Capacity
19 furnaces spanning ten distinct machine types — from induction hardening at 1000°C to fully automatic shaker hearth furnaces, nitriding, carburising, tempering, and reducing atmosphere controlled tilted furnaces.

From Machined Part to Heat-Treated Component
Every component entering our heat treatment section follows a structured, quality-verified thermal cycle — ensuring consistent case depth, hardness profile, and dimensional stability across every batch.
The Advantage of Our Thermal Processing Floor
With 6 distinct thermal processes — induction hardening, carburising, nitriding, tempering, rotary, and reducing atmosphere — our heat treatment section handles the full spectrum of metallurgical requirements for automotive, defence, and industrial components, entirely in-house without outsourcing.
Induction Hardening
Localised surface hardening up to 1000°C — hard case, tough core, minimal geometric distortion on shafts, pins, and high-wear surfaces.
Gas Carburising
Carbon diffusion at up to 1100°C in endothermic atmosphere — deep, consistent case depth for gears and transmission parts.
Nitriding — Zero Quench Distortion
Nitrogen diffusion at up to 1000°C — extreme surface hardness with no quench distortion on tight-tolerance components.
In-House Hardness Testing
Vickers hardness tester on-site — every batch verified before release, no external lab dependency or turnaround delays.
Fully Automatic Shaker Hearth
Automated batch processing at 800°C–1100°C for consistent cycle times and repeatability at high production volumes.
Integrated with Grinding & Plating
Heat treatment feeds directly into grinding, plating, and quality sections — complete single-vendor process continuity.
