Haynes* 230(UNSN06230)


Haynes 230 is a Ni-Cr-W-Mo alloy that  combines excellent high-temperature strength and oxidation resistance with  superior long term stability and good fabricability.

It boasts excellent oxidation  resistance to 2100°F and superior strength at temperature. This allows Haynes  230 to excel in creep and fatigue resistance at high temperatures. It also  exhibits excellent nitriding and carburization resistance comparable to that  of alloy 600.
