This bar’s versatility is a huge win. It’s stable up to 1093°C, which is more than enough for scrubber systems operating in high-heat conditions, like those in coal-fired power plants or petrochemical facilities. Its low thermal conductivity (~10 W/m·K) helps with thermal management, and its high strength ensures it holds up under mechanical stress. From industrial smokestacks to cleaner energy systems, 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 scrubber support design needs—think heavy-duty rods or sturdy fasteners. 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 flue gas desulfurization 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 regulations pushing for cleaner air and lower sulfur emissions—think decarbonization and green energy initiatives—demand for reliable materials like Hastelloy C-276 is soaring. Its low maintenance aligns with the trend toward cost-effective, sustainable solutions.

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 standout. Hastelloy C-22 is great for oxidizing acids but slightly less effective in reducing acid and sulfur environments. Stainless steel 316 is tough but struggles with chlorides and sulfur compounds, unlike C-276. Monel 400 is corrosion-resistant but lacks C-276’s high-temperature stability and sulfur resistance. Our bar is the go-to for flue gas desulfurization scrubber supports.

We craft our Hastelloy C-276 bar to meet strict standards like ISO 9001, ensuring quality you can trust every time.
