What makes Hastelloy B-3 bar stand out is its incredible ability to resist corrosion from hydrochloric, sulfuric, and other reducing acids. It’s perfect for structural rods in acid production units, fighting off pitting, crevice corrosion, and stress corrosion cracking to keep your equipment standing strong with minimal maintenance. This bar ensures your production stays safe and efficient, no matter how brutal the conditions get.
This bar’s versatility is a huge win. It’s stable up to 760°C, which is plenty for acid production units operating in moderate-heat environments, like those in chemical plants or fertilizer facilities. Its low thermal conductivity (~10 W/m·K) helps with thermal management, and its high strength means it can take on mechanical stress without cracking. From sulfuric acid plants to pharmaceutical processing, Hastelloy B-3 delivers.
We love how workable this bar is, especially compared to other high-performance alloys. Its improved fabrication stability makes it easier to machine, forge, or weld into whatever your structural rod design needs—think robust rods 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.

Compared to other materials, our Hastelloy B-3 bar is a clear winner. Hastelloy B-2 is great for acid resistance but less stable during fabrication and more prone to pitting. Stainless steel 316 is tough but struggles with strong acids like hydrochloric, unlike B-3. Monel 400 is corrosion-resistant but doesn’t match B-3’s performance in reducing acid environments. Our bar is the go-to for acid production unit structural rods.
We craft our Hastelloy B-3 bar to meet strict standards like ISO 9001, ensuring quality you can trust every time. Whether you’re building rods for acid reactors or supports for chemical equipment, this bar’s ready to perform. Got a unique spec in mind? Let us know, and we’ll make it happen.
