Hastelloy
Hastelloy is a high-performance nickel-molybdenum alloy, ideal for parts that require the highest corrosion resistance. It has outstanding resistance to pitting, stress, oxidation, chemicals, acids, and saltwater. Hastelloy also retains good ductility after prolonged high temperatures.
Hastelloy has a machining cost factor of 10.0 when compared to steel 12L14. It has excellent ductility and therefore can be readily welded and formed by hot and cold working. Hastelloy is typically heat treated and can be annealed.
Industries & Applications
- Oilfield parts
- Pipes
- Valve components
