We love how workable this strip is, even with its complex alloy makeup. You can stamp, form, or weld it into whatever your gasket design needs—think precision seals or robust linings. Need a specific width, thickness, or finish? We can tailor it to fit your specs, ensuring smooth fabrication and keeping your project on track.
The petrochemical industry’s all about materials that are tough, efficient, and sustainable, and Hastelloy C276 strip checks every box. It’s recyclable, which is great for eco-friendly projects, and its long lifespan means less waste from replacements. With global demand for petrochemicals, green fuels, and specialty chemicals soaring—think cleaner energy and sustainable refining—Hastelloy C276’s corrosion resistance is more critical than ever. Its low maintenance aligns with the trend toward cost-effective, green operations.

Our Hastelloy C276 strip sets the standard because we’re all about quality, customization, and customer success. We offer a wide range of widths, thicknesses, and finishes, with fast delivery for both small and large orders. Our team dives into your project, optimizing the strip for your petrochemical gaskets to ensure maximum corrosion resistance and performance. We keep pricing competitive, especially for bulk orders, without skimping on quality. Our sustainable production process uses recyclable materials, aligning with green industry trends. Plus, our hands-on support means you’re always covered—whether it’s technical guidance or a custom solution, we make it happen.
Compared to other materials, our Hastelloy C276 strip is a clear standout. Hastelloy C22 is great for oxidizing acids but slightly less effective in reducing acids and pitting scenarios. Stainless steel 316 is tough but struggles with strong acids and chlorides, unlike C276. Monel 400 is corrosion-resistant but lacks C276’s high-temperature stability and acid resistance. Our strip is the go-to for petrochemical processing gaskets.
We craft our Hastelloy C276 strip to meet strict standards like ISO 9001, ensuring quality you can trust every time. Whether you’re building gaskets for refineries or seals for chemical reactors, this strip’s ready to perform. Got a unique spec in mind? Let us know, and we’ll make it happen.
