Surface Hardening Services in Ludhiana, Punjab

Precision surface hardening and induction heating job work for steel, alloy, and industrial components across Punjab.

What Is Surface Hardening?

Surface hardening is a heat treatment process designed to strengthen only the outer surface of steel or alloy components while retaining a tough, ductile core. This process improves wear resistance, fatigue strength, and longevity without affecting internal properties — making it ideal for shafts, gears, spindles, and pins used in heavy-duty machinery.

Precision Heat Treatment for Shafts, Gears, & Components

Our localized surface hardening process ensures precise depth control, uniform hardness, and minimal distortion — essential for accuracy-driven components.

01

Induction Heating

Targeted heating of the component surface using electromagnetic coils.

02

Quenching

Immediate cooling using polymer or water-based quenching to form a hard surface layer.

03

Tempering

Optional reheating for enhanced toughness and reduced brittleness.

Why Choose Surface Hardening for Steel Components?

Surface hardening is one of the most effective ways to enhance component life without compromising flexibility and strength.

Increases Wear Resistance

Creates a hard, durable surface that withstands abrasion and friction.

Maintains Tough Core

The core remains tough and less brittle, preventing fractures under impact.

Localized Hardening

Hardens only specific areas where needed, reducing distortion and saving energy.

Reduces Distortion

Minimal distortion compared to through-hardening methods, preserving component geometry.
