About SUH660
SUH660
SUH660 is austenitic heat resistant steel. It provides a high strength under high temperature environments and is also used for materials for rotors, bolts, blades, and shafts of gas turbines and steam turbines with operating temperatures of 700°C . It may be used as an A286 equivalent product that is mainly used under high temperature environment.
Characteristics
- Retains high strength under high temperature environments.
- Performing age hardening after solution heat treatment provides tensile strength of 900 MPa or higher.
