Crafted from Hastelloy B-2 (UNS N10665) by a specialty alloy manufacturer with decades of expertise, this corrosion-resistant hex nut is made using precision forging and finish machining to ensure purity and exact thread geometry. Its nickel-molybdenum chemistry provides outstanding resistance to hydrochloric acid and other reducing environments, delivering long-term dimensional stability and reliable engagement even at elevated temperatures. Ideal for chemical processing, oil and gas, and marine applications, the nut combines exceptional corrosion resistance, mechanical strength, and tight tolerances to minimize maintenance and extend service life.
Our experienced metallurgical and manufacturing team brings deep expertise to every Hastelloy B-2 (UNS N10665) hex nut, ensuring core attributes—exceptional corrosion resistance, precise thread tolerances, and robust mechanical strength—are realized in production. Value attributes include rigorous quality control (MTRs, PMI, dimensional inspection), customized machining to spec, and traceable supply-chain management. This collective capability reduces installation risk, minimizes downtime, and extends service life in aggressive, reducing environments. Certified processes and rapid technical support enable reliable selection and faster delivery for critical applications. Trust in our team strength for consistent performance, compliance, and lifecycle cost savings in demanding chemical and petrochemical systems.
Our multidisciplinary team combines metallurgical expertise, precision machining and stringent quality control to deliver Hastelloy B-2 (UNS N10665) corrosion-resistant hex nuts that meet demanding industrial specifications. Core strengths include alloy selection knowledge, certified testing (chemical, mechanical and corrosion), CNC manufacturing, and full traceability from raw material to finished part. Value-driven services include rapid prototyping, customized thread and finish options, technical consultation, on-time delivery and responsive after-sales support. We ensure consistent performance in aggressive environments through robust process controls, ISO-compliant inspection and supply-chain reliability, giving customers confidence in component integrity and long-term operational uptime, backed by documented warranties and industry-recognized certifications worldwide.
Hastelloy B-2 is a nickel-molybdenum alloy with significant resistance to reducing environments, such as hydrogen chloride gas and sulfuric, acetic and phosphoric acids. Hastelloy B2 provides resistance to pure sulfuric acid and a number of non-oxidizing acids. The alloy should not be used in oxidizing media or where oxidizing contaminants are available in reducing media. Premature failure may occur if alloy B2 is used where iron or copper is present in a system containing hydrochloric acid.
Industry users like the resistance to a wide range of organic acids and the resistance to chloride-induced stress-corrosion cracking.
Hastelloy B2 resists the formation of grain boundary carbide precipitates in the weld heat-affected zone, making it suitable for most chemical process applications in the as-welded condition. The heat-affected weld zones have reduced precipitation of carbides and other phases to ensure uniform corrosion resistance.
Alloy B2 also has excellent resistance to pitting and stress corrosion cracking.
