Special Alloys
Special alloys are nickel-based and high-performance alloys, such as Inconel® 625 and 718, built for extreme heat, pressure and corrosion. We source them for oil and gas, power, chemical and aerospace applications.
When to Choose Special Alloys
- Service temperatures exceed what stainless steel can handle
- The environment is highly corrosive or sour
- Strength must hold at high temperature
- The part is for oil and gas, power, chemical or aerospace use
