Where Heat Becomes Performance.

Heat treatment is the controlled process of heating and cooling metals to alter their physical and mechanical properties without changing their shape. By precisely managing temperature, holding time, and cooling rate, the hardness, strength, ductility, toughness, and wear resistance of a component can be engineered to exact specification. The same grade of steel can be left soft enough to machine freely or made hard enough to resist heavy abrasion, depending entirely on how it is treated. At Chenab Engineering Works, we combine decades of foundry metallurgy with modern furnace control to deliver heat treatment that performs reliably under real working loads, from a single prototype to full production batches.

Controlled Atmosphere Furnaces

Precise Heat,
Predictable Results.

Every heat treatment outcome depends on uniform temperature and a protected furnace atmosphere. Our furnaces hold tight thermal tolerances and shield components from scaling and decarburisation, so the metallurgy you specify is the metallurgy you receive, batch after batch.

Core Processes

Hardening, Tempering, Annealing & Normalising

Most heat treatment work is built on a handful of fundamental cycles, each engineered to deliver a specific balance of properties. Hardening raises steel above its critical temperature and quenches it rapidly to lock in a hard martensitic structure, while tempering follows to restore toughness and remove the brittleness that hardening leaves behind.

Annealing softens metal and relieves internal stress for easier machining and forming, and normalising refines the grain structure to give uniform, repeatable mechanical properties across a full batch. Choosing the correct cycle for each component is where metallurgical judgement makes the difference between a part that lasts and one that fails early.

  • Through hardening and quenching in oil, water, or polymer
  • Tempering for a balanced blend of hardness and toughness
  • Full and process annealing for machinability and ductility
  • Normalising for uniform, fine-grain structure
  • Stress relieving for welded, machined, and cast parts

Surface & Case Hardening

A Hard Surface Over a Tough Core

Many components must resist surface wear while staying tough enough to absorb shock and fatigue. Case hardening achieves exactly this, diffusing carbon or nitrogen into the outer layer to create a hard, wear-resistant skin over a ductile core. Gears, shafts, cams, sprockets, and tractor linkage pins are typical candidates.

We offer carburising, carbonitriding, nitriding, and induction hardening, each suited to different geometries and distortion tolerances. For parts that cannot accept dimensional change, nitriding and induction hardening deliver high surface hardness with minimal distortion, while case depth is always controlled to the drawing specification.

  • Carburising and carbonitriding for low-carbon steels
  • Nitriding for wear and fatigue resistance with low distortion
  • Induction hardening for shafts, gear teeth, and pins
  • Flame hardening for large or localised surfaces
  • Controlled case depth to exact drawing specification

Our Heat
Treatment Process

A disciplined cycle from incoming inspection and material verification through controlled heating, quenching, tempering, and final hardness validation, fully documented at every stage.

01

Material Verification

Incoming inspection, grade confirmation, and review of the required specification, target hardness, and case depth.

02

Controlled Heating

Loading into atmosphere-controlled furnaces and heating to the precise austenitising or process temperature.

03

Quenching

Rapid, uniform cooling in the correct medium, oil, water, polymer, or air, to develop the target microstructure.

04

Tempering & Relieving

Reheating to relieve stress, restore toughness, and dial in the final balance of hardness and ductility.

05

Hardness & Inspection

Rockwell, Brinell, or Vickers testing, case depth checks, and full certification before dispatch.

Metallurgical Control

The Science Behind Every Cycle

Repeatable heat treatment depends on data, not guesswork. Our metallurgical laboratory monitors furnace temperature uniformity, quench performance, and atmosphere composition on every batch, so the results stay consistent from the first part to the last.

Hardness testing across the Rockwell, Brinell, and Vickers scales, combined with microstructure examination and case depth measurement, confirms that each component meets its specification before it leaves our facility, backed by a full test certificate.

Common Questions

Heat Treatment Services FAQs

What heat treatment services do you offer in Pakistan?
Our facility in Faisalabad provides a full range of heat treatment services, including hardening and quenching, tempering, full and process annealing, normalising, stress relieving, carburising, nitriding, and induction hardening. We treat steel and cast iron components for the agricultural, automotive, defence, and heavy machinery sectors, from single prototypes to large production batches.
How much does heat treatment cost?
Pricing depends on the process, material, part size, batch quantity, and the target hardness or case depth required. The most accurate way to get a figure is to share your drawing and specification with us, and we will return a detailed quotation. Larger production batches benefit from lower per-part pricing.
Which materials can you heat treat?
We routinely treat carbon steel, alloy steel, tool steel, grey iron, and ductile iron, along with stainless grades on a specialist basis. Our metallurgists can advise on the most suitable cycle for your material grade and intended application to achieve the right balance of hardness, strength, and toughness.
What is the difference between hardening and tempering?
Hardening heats steel above its critical temperature and quenches it rapidly to produce a hard but brittle structure. Tempering then reheats that hardened steel to a lower temperature to relieve internal stress and restore toughness. The two are almost always carried out together, since hardening alone leaves a part too brittle for service.
Can you achieve a specific hardness or case depth?
Yes. We work to your drawing and can target a defined hardness, for example a stated HRC or HB value, as well as a controlled case depth for surface hardened parts. Every cycle is verified by hardness testing and, where required, case depth measurement before the parts are released.
Do you provide hardness testing and certification?
Every batch is tested in our metallurgical laboratory using Rockwell, Brinell, or Vickers methods, with microstructure and case depth analysis where applicable. Each order can be supplied with a test certificate confirming the results meet your specification.
Where is your heat treatment facility located?
Our heat treatment and foundry facility is based in Faisalabad, Pakistan, and we serve manufacturers across Lahore, Karachi, and the wider region, as well as export customers. Contact us to arrange collection, delivery, or a discussion of your requirements.
