Diving into applications, our reducing acid-resistant Hastelloy B-2 strip is a go-to for sulfuric and hydrochloric acid handling. In chemical plants, it's ideal for reactors and piping where these acids are processed or stored, resisting corrosion even in pure reducing conditions. We've provided it for heat exchangers in acetic acid production and pumps in phosphoric acid systems, where it prevents stress-corrosion cracking under load. Pharmaceuticals love it for equipment handling hydrogen chloride gas without contamination risks. Beyond that, it's used in pollution control for scrubbers dealing with acidic gases and in waste treatment for vessels exposed to mixed reducing agents. At DLX, we customize our strip for these scenarios, ensuring it performs from -200°C to 450°C and in low-pH setups. This makes it a favorite for engineers tackling projects involving aggressive chemicals, reducing the chance of leaks or breakdowns.
What gives DLX the upper hand in this space? While there are various suppliers out there for acid-resistant alloys, our commitment to excellence really shines through. We don't just roll out Hastelloy B-2 strip; we refine it with cutting-edge vacuum melting and strict quality checks to eliminate defects, ensuring uniform resistance across every inch. This translates to equipment that holds up longer, slashing your repair bills. Unlike options that might overlook rigorous testing, we subject each batch to ultrasonic inspections, acid immersion simulations, and mechanical stress tests. Sustainability matters to us—we incorporate recycled nickel to lessen environmental impact without compromising on strength, appealing to green-focused clients in chemical sectors. Our delivery is speedy and reliable, handling everything from prototype quantities to large-scale orders. And our support team is on call for advice on integration, welding, or custom specs. When dealing with sulfuric or hydrochloric acids, where corrosion can spell disaster, partnering with DLX means opting for proven reliability.
Let's get technical on why our Hastelloy B-2 strip excels in reducing acids. Its high molybdenum content provides unmatched protection against hydrochloric acid at all strengths and temps up to boiling, and it handles sulfuric acid concentrations up to 70% without issue. The low carbon design avoids grain-boundary precipitates during welding, so no sensitization or intergranular corrosion. This is crucial in acid-handling systems with frequent welds. Though PREN is high at 65-70 due to molybdenum, its real strength is in non-oxidizing media—avoid ferric ions or oxidants. We've optimized the strip's finish to minimize surface attacks, enhancing longevity. Industry trends like automation in chemical processing favor materials like ours that integrate with robotic fabrication. With the market eyeing $13 billion by 2034 for corrosion-resistant alloys, DLX is innovating to meet demands for scalable, safe solutions in acid environments.
Expanding on applications, our strip is essential in petrochemical refineries for hydrochloric acid stripping columns and in fertilizer production for sulfuric acid tanks. In pharmaceuticals, it safeguards reactors during API synthesis involving reducing acids. We've supplied it for vacuum distillation units and even aerospace chemical systems where purity is non-negotiable. The unifying factor? Superior resistance that keeps operations humming without unexpected halts. As trends shift toward strategic market growth in chemicals, our Hastelloy B-2 strip supports that by enabling efficient, low-maintenance setups.
Stacking DLX against typical alternatives, our edges are obvious. We emphasize tailoring—while some offer generic strips, we adjust thicknesses, tempers, and even minor compositions to match your acid-handling needs, cutting waste and boosting efficiency. Pricing is transparent, valuing the extended life our product provides in harsh conditions. Our global network ensures steady supply amid fluctuations. We provide full mill test reports compliant with ISO 9001, giving you an advantage in audits. R&D at DLX continually improves properties, like enhancing ductility for tighter bends in piping.
