Hastelloy C-22 Bar for Corrosion-Resistant Marine Structural Components
Our Hastelloy C-22 bar is a total beast for corrosion-resistant marine structural components, built to take on the brutal saltwater environment without flinching. This nickel-chromium-molybdenum alloy, with about 56% nickel, 22% chromium, 13% molybdenum, plus a dash of tungsten and iron, is our go-to for applications where corrosion resistance and strength are critical. Whether it’s bolts, supports, or structural components for marine vessels and offshore platforms, this bar keeps your systems tough and reliable.
What makes Hastelloy C-22 bar stand out is its incredible ability to resist pitting, crevice corrosion, and stress corrosion cracking in seawater. It’s perfect for marine structural components, ensuring your vessel or platform stays strong and corrosion-free, whether it’s battling high-flow ocean waves or stagnant coastal waters. This bar keeps maintenance low and performance high, saving you time and money in harsh marine conditions.

This bar’s versatility is a huge win. It’s stable up to 1038°C, which is plenty for marine applications near engine compartments or in coastal processing plants with moderate heat. 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 commercial ships to offshore wind farms, Hastelloy C-22 delivers.
We love how workable this bar is, even with its complex alloy makeup. You can machine, forge, or weld it into whatever your structural design needs—think heavy-duty bolts or robust 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 marine industry’s all about materials that are durable, efficient, and sustainable, and Hastelloy C-22 bar checks every box. It’s recyclable, which is awesome for eco-friendly projects, and its long lifespan means less waste from replacements. With global demand for shipping, offshore energy, and desalination projects soaring—think green maritime solutions and sustainable ocean infrastructure—Hastelloy C-22’s seawater resistance is more critical than ever. Its low maintenance aligns with the trend toward cost-effective, eco-conscious operations.

Compared to other materials, our Hastelloy C-22 bar is a standout. Hastelloy C-276 is great for reducing acids but slightly less effective in oxidizing seawater environments. Stainless steel 316 is tough but struggles with chloride corrosion in saltwater, unlike C-22. Monel 400 is corrosion-resistant but lacks C-22’s high-temperature stability and strength in marine settings. Our bar is the go-to for corrosion-resistant marine structural components.
We craft our Hastelloy C-22 bar to meet strict standards like ISO 9001, ensuring quality you can trust every time. Whether you’re building bolts for ship hulls or supports for offshore platforms, this bar’s ready to perform. Got a unique spec in mind? Let us know, and we’ll make it happen.
