Carburizing Process

Carburizing & quenching enriches the surface carbon content (0.7–1.1% C) of low-carbon steel to form a hard martensitic layer while keeping the core tough.

Method: Gas carburizing in controlled furnaces.

Result: Improved fatigue strength, hardness, and wear resistance.

Hardening & Tempering Process

A two-step process to enhance strength and toughness in medium & high carbon steels.

Hardening: Steel is heated above the austenitizing temperature, then quenched to form hard martensite.

Tempering: The hardened steel is reheated to achieve tempered martensite, reducing brittleness.

Result: High strength with improved toughness and durability.

Normalizing Process

Steel is heated above its critical temperature, held for uniform austenite formation, and then air-cooled.

Result: Relieves stresses, improves toughness, hardness, and machinability.

Annealing Process

Steel is heated to a set temperature, held for transformation, and slowly cooled.

Result: Increased ductility, toughness, and reduced hardness, making the metal easier to work with.

Solution Annealing Process

Specially applied to stainless steels and aluminium alloys. Heated to dissolve unwanted precipitates followed by rapid quenching.

Result: Homogenized microstructure, improved machinability, and enhanced corrosion resistance.

Stress Relieving Process

Steel is heated below its critical temperature, held for a set duration, and cooled slowly.

Result: Increased dimensional stability, reduced distortion, and longer component life.
