Technical Specifications
Product Overview
Metallurgical Characteristics
GB 00Cr22Ni5Mo3N is a lean duplex stainless steel featuring a balanced microstructure of approximately 50% austenite and 50% ferrite phases. This dual-phase structure provides exceptional strength-to-weight ratio and superior corrosion resistance compared to conventional austenitic stainless steels. The nitrogen addition enhances both mechanical properties and pitting resistance.
Heat Treatment Process
MetalZenith employs precise solution annealing at 1020-1100°C followed by rapid cooling to achieve optimal phase balance. The controlled cooling rate prevents harmful intermetallic phase precipitation while maintaining the desired austenite-ferrite ratio. Post-annealing pickling removes heat tint and ensures uniform surface finish.
Manufacturing Process Excellence
Our integrated production process begins with vacuum induction melting using premium raw materials, followed by electroslag remelting for enhanced cleanliness. Hot working operations are carefully controlled within the temperature range of 950-1200°C to prevent phase imbalance. Cold working capabilities include precision rolling, drawing, and machining with specialized tooling designed for duplex steels.
Quality Standards & Testing
MetalZenith maintains compliance with international standards including ASTM A240, EN 10088, and JIS G4305. Comprehensive testing protocols include chemical analysis via optical emission spectroscopy, mechanical testing per ASTM A370, ferrite content measurement using magnetic methods, and corrosion testing including ASTM G48 pitting resistance evaluation. Each batch receives material test certificates with full traceability.
