On the application side, our stable thermal-resistant Hastelloy C-4 strip excels in high-temperature welded chemical scenarios. In chemical plants, it's perfect for reactors and heat exchangers where welding is constant, and temps soar—resisting stress corrosion cracking like a champ. We've supplied it for systems handling sulfuric acid, phosphoric acid, and even nitric acid mixtures without a hitch. Its ability to stay microstructure-stable during welding means no weak spots post-fabrication, which is crucial in high-pressure pipes for oil and gas. Pollution control apps love it too, like in scrubbers dealing with hot chlorine or sulfur compounds. For pharmaceuticals, it keeps things sterile in welded vessels exposed to aggressive cleaners and heat cycles. Beyond that, it's a staple in waste incinerators and aerospace-related chemical handling where thermal shocks are common. At DLX, we tailor our Hastelloy C-4 strip for these uses, ensuring it thrives from -200°C to 1038°C and in pH extremes. This versatility helps engineers tackle projects that demand reliability under fire—literally.
