At DLX, we’re proud to offer our stress-corrosion cracking resistant Hastelloy C4 UNS N06455 strip, designed to tackle the toughest acidic environments in chemical processing. If you’re searching for top-quality Hastelloy C4 strip suppliers, you’ve landed in the right spot. Our UNS N06455 strip is a nickel-chromium-molybdenum alloy built to withstand aggressive acids and high-stress conditions without cracking under pressure. Picture a material that holds strong against sulfuric or hydrochloric acid while keeping your equipment running smoothly—that’s what we deliver. With roughly 65-70% nickel for a solid core, 14-18% chromium to fend off oxidation, 14-17% molybdenum to combat pitting, and a dash of titanium (up to 0.7%) for extra stability, this alloy is a beast. We keep iron low at 3% max to avoid weak points, and toss in trace manganese, silicon, and carbon for balance. This isn’t just any strip; it’s a precision-engineered solution for acidic, high-stress applications. At DLX, we stick to strict ASTM B575 and ASME SB575 standards, offering strips in thicknesses from 0.05mm to 3mm and widths up to 600mm. Whether you need it annealed for flexibility or cold-rolled for strength, we’ve got you covered for seamless fabrication.

When it comes to applications, our stress-corrosion cracking resistant Hastelloy C4 strip is a versatile workhorse. In chemical processing, it’s perfect for reactors and piping exposed to acids like sulfuric, nitric, or phosphoric. Its resistance to stress-corrosion cracking makes it ideal for high-pressure systems in oil refineries, where welds face constant stress. We’ve supplied it for pollution control systems, like wet scrubbers tackling acidic sulfur compounds, and it holds up without pitting or cracking. In pharmaceuticals, it’s a go-to for welded vessels that handle aggressive cleaners during sterilization, ensuring no contamination. Beyond these, it’s used in waste incineration for handling acidic byproducts and in petrochemical plants for heat exchangers facing mixed acids. At DLX, we customize our Hastelloy C4 strip to thrive in temperatures from -200°C to 1038°C and in extreme pH levels, making it a favorite for engineers dealing with acidic, high-stress projects.
So, what makes DLX stand out in a crowded market? While there are other suppliers offering corrosion-resistant alloys, our focus on quality and innovation sets us apart. We don’t just produce Hastelloy C4 strip; we craft it with advanced vacuum melting and precision rolling to ensure a flawless microstructure—no inclusions that could lead to cracks. This means your equipment lasts longer, saving you on maintenance costs. Unlike some who skimp on testing, we run every batch through ultrasonic, eddy current, and acid exposure tests to guarantee performance. Sustainability is a big deal for us—we use recycled materials where possible without sacrificing strength, which resonates with clients aiming for greener operations.
