In the high-stakes world of aerospace, automotive, and precision tooling, the difference between a part that lasts and a part that fails is measured in microns. S R Thermal provides industry-leading Gas Nitriding Furnaces engineered for global manufacturers who demand precision, repeatability, and environmental compliance.
From the automotive hubs of Turkey and the USA to the precision molding sectors in the Philippines and Canada, S R Thermal is the trusted partner for "Zero-Distortion" case hardening.
Precision Nitriding Technology for a Global Market
At S R Thermal, we understand that modern heat treatment is no longer just about heating metal; it’s about Ammonia Dissociation Control and maintaining the perfect Nitriding Potential ($K_N$). Our systems are designed to provide:
White Layer Control: Achieve the exact compound zone thickness required for your specific application.
Ferritic Nitrocarburizing (FNC): Enhance both wear and corrosion resistance in a single cycle.
Post-Oxidation Surface Treatment: A sustainable alternative to chrome plating, ideal for marine and oil & gas components.
Regional Industrial Solutions: Where S R Thermal Leads
🇺🇸 USA & 🇨🇦 Canada: Aerospace & EV Excellence
In North America, the shift toward Electric Vehicles (EVs) and high-spec Aerospace parts requires strict adherence to standards.
Our Solution: AMS 2750 Compliant Furnaces and NADCAP-ready equipment.

Turkey is a critical link in the global supply chain, from Bursa to Istanbul.
Our Solution: High-capacity Pit-Type Nitriding Furnaces for long shafts and Aluminium Extrusion Die Nitriding systems.
Local Impact: S R Thermal helps Turkish OEMs transition from outdated salt bath methods to modern, eco-friendly Gaz Nitrürasyon Fırını technology.
🇵🇠Philippines: Precision Tool, Die, and Semiconductors
The Philippine manufacturing sector is rapidly evolving in the Cavite and Laguna industrial belts.
Our Solution: Small Batch Box-Type Furnaces specifically calibrated for Precision Mold Hardening.
Key Advantage: We provide affordable, high-efficiency hardening for injection molds and die-casting tools, ensuring local shops can compete globally.
Why S R Thermal is the Global Choice for 2026
1. Sustainability: Reducing Ammonia Consumption
With global energy prices rising, S R Thermal’s Energy-Efficient Nitriding Systems utilize advanced atmosphere sensing to reduce ammonia waste by up to 20%, significantly lowering your OPEX.
2. The Move Away from Salt Baths
Environmental regulations in Canada and the USA are making liquid nitriding (salt baths) obsolete. S R Thermal provides a seamless transition to Gas Nitriding, offering better safety, easier disposal, and superior surface finishes.
3. Automated Process Control
Our "set-and-forget" Automated Nitriding Process Control ensures that whether your plant is in Nairobi or Detroit, the quality of the case hardening remains identical every single time.
