If you're tackling pollution control projects with harsh acids and gases, our Incoloy 825 bar provides the durability and resilience you need to keep systems running efficiently.
Let's begin with the product introduction. Our Incoloy 825 bar is formulated from a nickel-iron-chromium alloy, featuring 38-46% nickel, 19.5-23.5% chromium, and iron as the base, enhanced with 2.5-3.5% molybdenum, 1.5-3% copper, and 0.6-1.2% titanium. This blend delivers exceptional acid resistance, making it ideal for pollution control system acid-resistant structures. With tensile strength up to 145 ksi in cold-worked form and yield at 129 ksi, it stands strong under stress. Density is 0.294 lb/in³, and the melting range hits 2500-2550°F, allowing it to handle elevated temperatures without losing integrity. We offer bars in various diameters, annealed or cold-worked, tailored for fabrication into beams, supports, and frames in pollution control setups. In acid-laden atmospheres, it keeps corrosion rates low, like under 2.3 mpy in boiling sulfuric acid, ensuring long-term performance for your acid-resistant structures.

Applications for our Incoloy 825 bar are extensive, particularly in pollution control system acid-resistant structures. In scrubbers and absorbers, it forms robust frames and supports that resist sulfuric and hydrochloric acids without pitting or cracking. Chemical processing plants use it for tanks and ducts handling phosphoric acid, where its copper addition enhances resistance to reducing environments. Oil and gas operations benefit from its use in manifolds exposed to sour gases, but in pollution control, it excels in evaporators and stacks for waste incineration. We've supplied it for nuclear waste processing structures, enduring radioactive acids, and in pickling lines for steel mills facing nitric mixes. Marine pollution control systems leverage its seawater resistance too. With thermal conductivity at 678 Btu-in/ft²•h•°F, it manages heat in high-temp scrubbers, preventing thermal fatigue. Our bars adapt to welded or machined forms, fitting custom acid-resistant structures seamlessly.
In comparing our company to the broader market, our advantages in providing Incoloy 825 bar for pollution control shine through dedication to quality and customization. We engineer bars with precise annealing at 1725-1775°F to maximize acid resistance, achieving elongation up to 30% for flexible designs. Our testing simulates pollution control conditions, like exposure to boiling acids, ensuring corrosion rates stay minimal. Lead times are swift—often within weeks—thanks to our stocked inventory, unlike slower options. Technical support guides fabrication, recommending hot-forging at 1600-2150°F to avoid issues, and we offer welding tips for GTAW that maintain integrity. While some providers overlook specs, we strictly follow UNS N08825, with optimal molybdenum for pitting resistance at 85°F CPT, leading to 25-30% longer lifespan in acid-resistant structures per client insights. This cuts maintenance costs significantly in pollution control systems.
Delving further into the product, our Incoloy 825 bar boasts excellent machinability and weldability, no preheat required, making it user-friendly for complex pollution control builds.
