Technical Specifications
Product Overview
Metallurgical Characteristics
UNS N06022 exhibits a face-centered cubic austenitic structure with exceptional stability across a wide temperature range. The alloy's unique combination of chromium, molybdenum, and tungsten provides outstanding resistance to localized corrosion, including pitting, crevice corrosion, and stress corrosion cracking. MetalZenith's controlled solidification process ensures optimal carbide distribution and grain boundary chemistry.
Heat Treatment Process
Standard solution annealing is performed at 1120°C (2050°F) followed by rapid cooling to prevent carbide precipitation. MetalZenith utilizes precision-controlled atmosphere furnaces with ±5°C temperature uniformity. Post-heat treatment surface conditioning removes oxidation while maintaining dimensional accuracy. Stress relief treatments at 870°C may be applied for welded components.
Manufacturing Process
Production begins with vacuum induction melting of premium raw materials, followed by electroslag remelting for enhanced cleanliness. Hot working operations utilize computer-controlled rolling and forging equipment maintaining precise temperature profiles. Cold working capabilities include precision rolling, drawing, and forming operations with intermediate annealing cycles as required.
Quality Standards & Testing
MetalZenith maintains comprehensive quality systems compliant with ISO 9001:2015, AS9100D, and NADCAP requirements. Testing protocols include chemical analysis via ICP-OES, mechanical property verification, ultrasonic examination, liquid penetrant inspection, and specialized corrosion testing including ASTM G48 and G28 methods. Full material traceability and certification documentation accompany all shipments.
