Heat Treatment Services
We specialize in precision heat treatment for ferrous and non-ferrous metals, enhancing mechanical properties and durability. Our processes include:
Annealing: Full, spheroidize, and solution annealing for improved machinability and stress relief.
Hardening & Tempering: Flame hardening, martempering, and marquenching for superior wear resistance.
Case Hardening: Gas carbonitriding, nitriding (liquid/gas), and nitrocarburizing for enhanced surface durability.
Specialized Treatments: Austempering, ausquenching, and stress relieving to optimize material performance.
Surface & Substrate Treatments
Anti-Corrosion Coatings: Blackodizing, phosphating (zinc, manganese, iron), and QPQ (quench-polish-quench) for corrosion and wear resistance.
Lubricant Coatings: Molybdenum disulfide (Moly), Xylan, and Alfa Moly coatings to reduce friction and improve longevity.
Custom Furnace Solutions
We design and manufacture industrial furnaces, including:
Car Bottom Furnaces – For heavy-duty batch processing.
Bell-Type Furnaces – Uniform heating for precision components.
Vertical Pit Furnaces – Ideal for long or vertically stacked parts.
Quality Assurance & Testing
Metal Testing: Rigorous evaluation of hardness, microstructure, and tensile strength.
Process Validation: Compliance with international standards (ISO, ASTM).

Austempering and Ausquenching
Austempering: A specialized quenching process that produces bainitic microstructure, improving toughness and reducing distortion in steels.
Ausquenching: A controlled quenching method to achieve martensitic transformation without excessive cracking or warping.
Furnace Size - (600 Ø X 800 mm Length)
Nitriding
Enhances surface hardness and wear resistance without quenching.
Gas Nitriding: For deep case depth and superior fatigue resistance in precision parts.
