Horizontal Gas Nitriding Furnaces by S R Thermal Enhance the wear resistance, fatigue strength, and corrosion protection of your components with S R Thermal’s Horizontal Gas Nitriding Furnaces. Our horizontal configurations are designed for ease of loading, exceptional process repeatability, and uniform ammonia (NH₃) distribution. By diffusing nitrogen into the surface of the metal at sub-critical temperatures, our furnaces create a hard, wear-resistant “case“ while maintaining the core properties of your precision-machined parts. The S R Thermal Engineering Advantage Precision is everything in nitriding. Our horizontal furnaces are engineered to solve the common challenges of surface treatment :Atmosphere Precision: Integrated ammonia dissociation control systems allow for exact regulation of the nitriding potential ($K_n$), giving you total control over the compound (white) layer thickness. Horizontal Loading Efficiency: The horizontal design is ideal for long shafts, heavy dies, and components that require specific fixturing, allowing for easier integration with factory rail systems or forklifts. Uniform Gas Distribution: High-performance internal fans and advanced manifold systems ensure the nitriding atmosphere reaches every crevice, even in high-density loads. Accelerated Cooling: Our furnaces feature optional rapid-cooling systems to reduce cycle times, increasing your facility's daily throughput. Technical Capabilities Feature Specification Process Temperature480°C to 600°CControl System Automated PLC with HMI for “Set-and-Forget“ cycles Heating Source Electric (Radiant Tubes) or Gas-Fired options Environment Controlled Ammonia (NH₃), Nitrogen (N₂), and optional CO₂ Sealing High-temperature vacuum-tight door seals to prevent gas leakage Key Benefits for Your Components High Surface Hardness: Dramatically increases the lifespan of gears, cams, and extrusion dies.Low Distortion: Since the process occurs at lower temperatures than traditional hardening, there is no phase change in the steel, resulting in near-zero dimensional distortion.Corrosion Resistance: The formed nitride layer provides an inherent barrier against moisture and chemical oxidation. Improved Fatigue Life: Induces compressive surface stresses that prevent cracks from forming under heavy loads. Typical Applications S R Thermal’s Horizontal Nitriding systems are the preferred choice for:Plastic Machinery: Extrusion screws and barrels. Automotive: Crankshafts, valves, and piston rings. Tool & Die: Forging dies and aluminum extrusion dies.Aerospace: High-wear precision gears and actuators. Partner with S R Thermal for Surface Excellence At S R Thermal, we don't just provide the furnace; we provide the process expertise. Our team helps you calibrate your gas recipes to ensure you meet specific metallurgical standards (like AMS 2750F or equivalent).
