Case Hardening Job Work in Ludhiana, Punjab

Reliable, precise, and controlled case hardening services for steel components used in industrial, automotive, and agricultural sectors.

What Is Case Hardening?

Case hardening is a thermo-chemical heat treatment process that increases the surface hardness of low-carbon or alloy steel components by infusing carbon or nitrogen atoms into the outer layer. The result — a hard, wear-resistant surface (case) and a tough, ductile core that resists impact and fatigue.

Industrial Case Hardening Process Explained

Our combination of depth hardening and quenching ensures a durable, high-wear-resistant surface — ideal for automotive and industrial parts.

Heating

Components are heated to a high temperature (900°C–950°C) in a carbon-rich atmosphere.

Carburizing/Nitriding

Carbon or nitrogen diffuses into the steel surface, creating the 'case'.

Quenching

Rapid cooling using polymer or water locks in the surface hardness.

Tempering & Inspection

Reheating to improve toughness, followed by rigorous testing for quality assurance.

Why Choose Case Hardening for Steel Components?

Excellent Wear Resistance

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

Tough Core

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

Improved Impact Strength

The combination of a hard case and tough core enhances overall component durability.

Cost-Effective

An efficient process for batch production, offering great value for high-volume work.
