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?
Creates a hard, durable surface that withstands abrasion and friction.
The core of the component remains tough and less brittle, preventing fractures under impact.
The combination of a hard case and tough core enhances overall component durability.
An efficient process for batch production, offering great value for high-volume work.
