Technical Specifications
Product Overview
Metallurgical Characteristics
GB 00Cr17Ni14Mo2 exhibits a fully austenitic microstructure at room temperature, characterized by face-centered cubic crystal structure that provides excellent ductility and toughness. The low carbon content (≤ 0.030%) minimizes carbide precipitation, while molybdenum addition enhances pitting and crevice corrosion resistance, particularly in chloride environments.
Heat Treatment Process
MetalZenith employs precise solution annealing at 1040-1100°C followed by rapid cooling to achieve optimal properties. This process dissolves carbides, homogenizes the microstructure, and maximizes corrosion resistance. Post-annealing pickling removes heat tint and surface oxidation, ensuring superior surface quality.
Manufacturing Excellence
Our manufacturing process begins with carefully selected raw materials melted in electric arc furnaces with argon-oxygen decarburization (AOD) refining. Secondary metallurgy ensures precise chemistry control, while continuous casting produces high-quality billets. Subsequent hot rolling, cold working, and finishing operations are performed under strict quality control to achieve specified mechanical properties and surface finish.
Quality Standards and Certification
All GB 00Cr17Ni14Mo2 products undergo comprehensive testing including chemical analysis by optical emission spectroscopy, mechanical testing per ASTM standards, ultrasonic inspection for internal soundness, and dimensional verification. MetalZenith maintains ISO 9001:2015, ISO 14001:2015, and OHSAS 18001 certifications, ensuring consistent quality and environmental responsibility. Material test certificates (MTC) per EN 10204 3.1 are provided with every shipment, guaranteeing full traceability and compliance with international standards.
