This bar’s versatility is a huge win. It’s stable up to 1093°C, which is awesome for pump shafts in high-heat settings, like those in petrochemical plants or acid production facilities. Its low thermal conductivity (~10 W/m·K) helps with thermal management, and its high strength ensures it can handle mechanical stress without cracking. From fertilizer manufacturing to pharmaceutical processing, Hastelloy C-276 delivers.
We love how workable this bar is, even with its complex alloy makeup. You can machine, forge, or weld it into whatever your pump shaft design needs—think precision shafts or sturdy supports. Need a specific diameter, length, or finish? We can tailor it to fit your specs, ensuring smooth fabrication and keeping your project on track.
The chemical processing industry’s all about materials that are tough, efficient, and sustainable, and Hastelloy C-276 bar 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 acids, fertilizers, and specialty chemicals growing—think green chemistry and battery production—Hastelloy C-276’s acid resistance is more critical than ever. Its low maintenance aligns with the trend toward cost-effective, sustainable operations.

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 C-276 bar is a clear winner. Hastelloy C-22 is great for oxidizing acids but slightly less effective in reducing acids like hydrochloric. Stainless steel 316 is tough but struggles with strong acids and chlorides, unlike C-276. Monel 400 is corrosion-resistant but doesn’t match C-276’s performance in high-temperature acid environments. Our bar is the go-to for hydrochloric acid-resistant pump shafts.
We craft our Hastelloy C-276 bar to meet strict standards like ISO 9001, ensuring quality you can trust every time. Whether you’re building pump shafts for acid reactors or supports for chemical systems, this bar’s ready to perform. Got a unique spec in mind? Let us know, and we’ll make it happen.
