Robust Hastelloy B2 UNS N10665 Strip for Chemical Processing and Vacuum Furnace Systems
At DLX, we're all in on our robust Hastelloy B2 UNS N10665 strip, tailored for the rigors of chemical processing and vacuum furnace systems. If you're scouting for dependable Hastelloy B2 strip suppliers who deliver quality without the hassle, here's why our UNS N10665 strip is a solid pick. This nickel-molybdenum alloy is built tough for reducing environments where corrosion could wreck havoc. Think of it as your go-to material that stands up to hydrochloric acid at any concentration or sulfuric acid blends, all while keeping things stable in high-heat vacuum setups. With nickel clocking in at 68-70% for that strong backbone, 26-30% molybdenum to amp up resistance in reducing acids, and super low iron (under 2%) and chromium (under 1%) to dodge oxidation pitfalls, it's fine-tuned for performance. We cap carbon at 0.01% to skip weld issues, and mix in tiny bits of cobalt, manganese, and silicon for the right balance. At DLX, we follow rigorous ASTM B333 and ASME SB333 specs, rolling out strips from 0.05mm to 3mm thick and up to 600mm wide. Annealed for easy forming or cold-rolled for extra strength, our Hastelloy B2 strip slots perfectly into your projects.

Let's break down why our Hastelloy B2 strip rocks technically. High molybdenum zaps corrosion in hydrochloric acid up to boiling and sulfuric up to 70%, minus ferric ions or oxidants. Low carbon skips precipitates in welds, no sensitization or intergranular hits—key for chemical piping and furnace welds. PREN hits 65-70 thanks to molybdenum, but it shines in non-oxidizing zones. We've smoothed surfaces to cut attacks, upping life spans. Trends like AI in manufacturing? We're using it for predictive checks on UNS N10665 production, nailing flaws early. The Ni-based superalloy market's eyeing $8.2 billion by 2032 from $5 billion in 2023, underscoring needs for high-performers like ours.
