Durable Hastelloy B-2 UNS N10665 Wire for Chemical Processing and Pollution Control Systems
At DLX, we're constantly innovating to meet the demands of tough industrial settings, and our Durable Hastelloy B-2 UNS N10665 Wire for Chemical Processing and Pollution Control Systems exemplifies that commitment. This wire is designed to withstand the rigors of corrosive environments, ensuring your operations run smoothly without unexpected failures. We've crafted it with precision, drawing on our expertise to provide a product that's reliable, versatile, and built to last in chemical processing and pollution control applications.
Let's kick things off with a closer look at the product itself. Our Durable Hastelloy B-2 UNS N10665 Wire is a premium nickel-molybdenum alloy, featuring a balanced composition that includes nickel at around 65-68% as the base, 28% molybdenum for that core corrosion resistance, and strict limits on impurities like iron at 2% max, chromium at 1% max, and carbon at just 0.01% max. This setup makes it incredibly resistant to reducing acids and environments where oxidants are absent, preventing issues like pitting, crevice corrosion, and stress-corrosion cracking. Mechanically, it's a powerhouse with tensile strength reaching 110 ksi, yield strength at 51 ksi, and elongation up to 60%, all while maintaining a density of 9.22 g/cm³. It performs well up to 1500°F in non-oxidizing conditions, making it perfect for heated processes. At DLX, we offer this wire in a variety of diameters and forms, from fine gauges for detailed components to heavier strands for structural elements. Its durability shines in chemical processing, where it handles harsh acids without degrading, and in pollution control systems, where it stands up to acidic gases and condensates. We've optimized it for weldability too, though we recommend controlled heat inputs to avoid any heat-affected zone sensitivities—resulting in joints that are as tough as the wire itself.

Applications for our Durable Hastelloy B-2 UNS N10665 Wire are diverse and critical in high-stakes environments. In chemical processing, it's a staple for reactors and piping dealing with hydrochloric, sulfuric, or phosphoric acids—corrosion rates stay below 0.1 mm/year even in boiling solutions, keeping production lines efficient. Pollution control systems benefit hugely; think flue gas desulfurization units or scrubbers where acidic condensates could corrode standard materials—our wire resists those attacks, extending system lifespan and reducing downtime. We've deployed it in pharmaceutical manufacturing for pure acid handling, ensuring no contamination in sensitive processes. Vacuum furnaces use it for components exposed to reducing atmospheres at high temps, while fertilizer plants rely on it for phosphoric acid environments. At DLX, we tailor the wire for specific setups, like welding fillers in tank linings or meshes in filtration systems. It's also finding traction in marine pollution control, handling saltwater-mixed acids, and even in renewable energy for biofuel processors facing organic reducers. The wire's ability to maintain integrity in non-oxidizing conditions makes it indispensable, offering peace of mind in operations where failure isn't an option.
When we stack our product against offerings from other companies, the advantages of choosing DLX become crystal clear. While many alternatives struggle with consistency in reducing environments, our Hastelloy B-2 UNS N10665 wire delivers superior resistance without the pitfalls of higher-chromium alloys that falter in pure reducers. Some competitors' wires are prone to quicker sensitization during welding, but ours, with its low carbon control, holds up better, requiring careful but straightforward fabrication techniques. In chemical processing and pollution control, this means fewer field repairs and longer intervals between inspections. Mechanically, our wire's high elongation and strength provide better performance under stress, outlasting generic options in cyclic operations.
