Technical Specifications
Product Overview
Metallurgical Characteristics
UNS N06200 (Hastelloy X) exhibits a face-centered cubic (FCC) austenitic structure that provides exceptional thermal stability and resistance to oxidation at elevated temperatures. The alloy's unique combination of nickel, chromium, iron, and molybdenum creates a solid solution strengthened matrix with excellent creep resistance and thermal fatigue properties.
Heat Treatment Process
MetalZenith employs precise solution annealing at 1175°C followed by rapid cooling to achieve optimal mechanical properties. This heat treatment dissolves carbides and ensures uniform grain structure. Post-fabrication stress relief at 870°C may be applied for complex geometries to minimize residual stresses while maintaining corrosion resistance.
Manufacturing Process Excellence
Our advanced manufacturing process begins with vacuum induction melting (VIM) using premium raw materials, followed by vacuum arc remelting (VAR) for enhanced cleanliness. Hot working operations are performed within controlled temperature ranges of 1095-1175°C, followed by solution annealing and precision finishing to achieve specified dimensional tolerances and surface quality.
Quality Standards & Testing
All UNS N06200 products undergo comprehensive testing including chemical analysis via optical emission spectroscopy, mechanical testing per ASTM standards, ultrasonic examination for internal soundness, and high-temperature oxidation testing. Our quality management system complies with ISO 9001:2015, AS9100D, and NADCAP certifications, ensuring consistent quality for critical aerospace and industrial applications.
Corrosion Resistance & Performance
The alloy demonstrates exceptional resistance to oxidizing and reducing environments, including excellent performance in carburizing and nitriding atmospheres up to 1200°C. Its chromium content provides superior oxidation resistance, while molybdenum enhances resistance to pitting and crevice corrosion in chloride-containing environments.
