Leveraging its integrated service capabilities of "precision CNC machining + professional nitriding," we provide customized nitriding solutions for the automotive, aerospace, mold and die, hydraulic, and other industries. Our CNC machining capabilities enable ultra-mirror finishes to within ±0.002mm. As a professional supplier of packaging machinery components, our complementary precision gear machining and precision casting manufacturing capabilities are also worthy of your trust. What is nitriding treatment? Nitriding treatment is a heat treatment process that forms a high hardness and high wear resistant nitride layer by infiltrating nitrogen atoms into the metal surface. Suitable for materials such as steel, cast iron, titanium alloys, etc., it significantly improves the fatigue strength, corrosion resistance, and bite resistance of components while maintaining the toughness of the substrate. Advantages of Nitriding Treatment - Ultra high surface hardness (HV 1000-1200) - more wear-resistant than traditional quenching - Minimal deformation - the ideal choice for precision parts after machining - Excellent corrosion resistance - salt spray test can reach over 500 hours - Improved anti fatigue performance - extending component life by 3-5 times Our nitriding treatment technology - Gas Nitriding - Temperature range: 500-580 ℃ - Depth of infiltration layer: 0.1-0.6mm - Applicable materials: alloy steel (such as 4140, 4340), mold steel (H13) - Plasma Nitriding - Low temperature process (350-450 ℃) to reduce deformation - Precise control of infiltration layer, suitable for complex geometric parts - Environmentally friendly and pollution-free, compliant with RoHS standards - Salt bath nitriding (QPQ) - Composite treatment (nitriding+oxidation), combining wear resistance and corrosion resistance - Surface smoothness Ra ≤ 0.8 μm Typical application areas - Automotive industry: crankshafts, camshafts, gears - Aerospace: Landing gear components, turbine blades - Mold manufacturing: injection molds, die-casting molds - Hydraulic system: plunger pump, valve core Technical Specifications / Features - Process types: Gas Nitriding, Plasma Nitriding, Salt Bath Nitriding (QPQ) - Surface hardness: HV 1000-1200 - Deformation: Minimal, suitable for precision parts - Corrosion resistance: Salt spray test > 500 hours - Fatigue performance: Component life extended by 3-5 times - Gas nitriding temperature: 500-580 ℃ - Gas nitriding layer depth: 0.1-0.6mm - Plasma nitriding temperature: 350-450 ℃ - Salt bath nitriding surface roughness: Ra ≤ 0.8 μm - Applicable materials: Steel, cast iron, titanium alloys, alloy steel (4140, 4340), mold steel (H13) - Compliance: RoHS standards (for plasma nitriding)
