From sea water to strong acids
Corrosion is one of the most common causes of fastener failure. From salt water applications to hot concentrated acids, Extreme Bolt & Fastener offers the most corrosion resistant fasteners to protect against even the harshest applications. Below are guides showing the performance of a variety of corrosion resistant fasteners in various corrosive media, as well as a general comparison of specialty metal and engineered polymer fasteners. We also have resources to better help your understanding of the types of corrosion you may face. In-depth, information can also be found on the material specific sections of this site. For additional assistance, contact our experienced engineering staff to help guide you to the best material.
- Salt water / Sea water
- Hydrobromic Acid (HBr)
- Hydrochloric Acid (HCl)
- Hydrofluoric Acid (HF)
- Nitric Acid (HNO3)
- Phosphoric Acid (H3PO4)
- Sulfuric Acid (H2SO4)
Specialty metal fasteners provide corrosion solutions to even the harshest chemical environments, as well as marine and salt water applications. Though their performance varies greatly by material and corrosive environment, the chart below will give you a general guide on the most verses least resistant materials (though actual corrosion resistance could be very different based on the exact environment). For more in-depth information, visit our material specific pages or contact one of our engineers.

- Hastelloy, zirconium and tantalum hydrochloric acid corrosion comparison
- Hastelloy, zirconium and tantalum corrosion sulfuric acid comparison
Though polymer fasteners can’t handle the high temperatures of metals, they do have the ability to provide excellent corrosion resistance acidic conditions. This chart gives you a basic perspective of their corrosion capabilities. For more information on each polymer, visit our material specific pages or contact one of our engineers.
