CNC Machined Hastelloy Components

aluminumHastelloy superalloys are popular for high-temperature, high-stress environments. Superior Joining Technologies, Inc. has the experience and expertise in manufacturing CNC machined Hastelloy components. We also offer Hastelloy welding services and Hastelloy NDT inspection services.

Hastelloy can withstand a corrosive environment where iron-based alloys would fail. Hastelloy is known for its outstanding resistance to pitting, stress, oxidation, chemicals, acids, and saltwater. Additionally, they retain good ductility after prolonged temperatures and function well under high mechanical stress.
