One cycle, two aims
Quenching raises hardness. Tempering gives back toughness so the part can work in service. Skipping temper leaves hardened steel brittle.

Hardening and tempering services in Ludhiana
Quench and temper job work at our plant in Ludhiana (Pawa, G.T. Road), for production steel parts that need hardness and toughness together.
Hardening and tempering
What the two steps do
Hardening and tempering services in Ludhiana (Pawa, G.T. Road) are for steel parts that must be hard in service and still tough enough to survive it.
Hardening on its own is only half the job. A quenched part is hard and, until it is tempered, too brittle for most production uses. Tempering is a second heating, lower than the hardening range, that lets the structure relax enough for the hardness and toughness on your drawing to sit together. The cycle follows the grade and the specification, and we confirm it with you before a lot is loaded.
In practice
How a hardening and tempering lot is handled
Set from your drawing
Grade, section and the hardness on the specification decide the cycle. It is agreed before the lot is loaded, then kept the same for repeat lots.
Checked before release
Hardness is tested in our own lab. Lot records tie the result to the inward documents.
Next operation, same plant
Scale after treatment can go to shot blasting, and the part can be machined here, instead of moving to another supplier.

Where this sits in the plant
Volume lots of small and medium parts run on the continuous furnace described under mesh belt hardening and tempering job work. If the drawing asks for a refined structure before this step, normalizing can come first. After treatment, shot blasting removes scale and CNC machining can finish the part in the same plant at Ludhiana (Pawa, G.T. Road).
The parent page, heat treatment in Ludhiana, compares this route with normalizing.

Hardening and tempering: common questions
Straight answers before you raise an RFQ.
What do hardening and tempering services include?
Hardening heats the steel through the range suited to its grade and quenches it so hardness increases. Tempering reheats the part below that range so brittleness drops and hardness moves to the value on your specification. Both steps are part of the same job. The part is checked for hardness before it is released.
Do you offer hardening and tempering services in Ludhiana?
Yes. Hardening and tempering services in Ludhiana are job work at our plant in Ludhiana (Pawa, G.T. Road). Production volumes of small and medium parts run as mesh belt hardening and tempering.
How is this different from normalizing?
Normalizing cools in air. It is used to even out grain and reduce stress, often before machining. Hardening uses a quench, so the hardness increase is greater, and tempering is then required so the part is not left brittle. The drawing, not a catalogue, decides which one you need.
Which components are a good fit?
Repeat production parts whose size suits a continuous furnace: fasteners, pins, bushes, small gears, small shafts and similar steel components. If the section is large or the geometry is awkward, send the drawing anyway. We will say whether this route fits or whether another process in the plant is the better discussion.
What should I send for a quote?
The drawing, material grade, the hardness the specification asks for, quantity per lot and how often lots will come. Send your drawing for a quote. A trial lot is the usual way to start.
