Technical Specifications
Product Overview
Metallurgical Characteristics
UNS N10665 is a solid-solution strengthened nickel-molybdenum alloy with exceptional corrosion resistance in reducing environments. The high molybdenum content (26-30%) provides outstanding resistance to hydrochloric acid, sulfuric acid, and other reducing media. The alloy maintains its corrosion resistance at temperatures up to 650°C and exhibits excellent thermal stability.
Heat Treatment and Processing
MetalZenith employs solution annealing at 1065-1120°C followed by rapid cooling to achieve optimal properties. The alloy cannot be hardened by precipitation hardening but gains strength through cold working. Our controlled atmosphere heat treatment prevents oxidation and maintains surface quality. Hot working is performed between 1010-1175°C with careful temperature control to prevent cracking.
Manufacturing Process Excellence
Our manufacturing process begins with vacuum induction melting using high-purity raw materials, followed by vacuum arc remelting for enhanced cleanliness. The ingots undergo homogenization heat treatment before hot working operations. MetalZenith's advanced rolling and forging capabilities ensure uniform microstructure and mechanical properties throughout the product cross-section.
Quality Standards and Testing
All UNS N10665 products undergo comprehensive testing including chemical analysis by optical emission spectroscopy, mechanical testing per ASTM standards, ultrasonic examination, and specialized corrosion testing. MetalZenith maintains full traceability from raw materials to finished products, with detailed documentation including mill test certificates, heat treatment records, and dimensional inspection reports. Our quality system complies with ASTM B333, NACE MR0175, and other relevant international standards.
