CEWELD 16.8.2-17

Product category
Type
A specially designed hybrid alloy between 308H and 316H for high temperature applications.
Applications
Used mainly in power generation and chemical process industries on applications such as, steam turbines, catalytic crackers, transfer piping and furnace accessories.
Properties

A specially designed composition where Molybdenum % is reduced to form a hybrid alloy between 308H and 316H, operates in temperatures up to 800 °C. CEWELD® 16.8.2-17 gives a very high resistance to thermal embrittlement. Creep ductility is enhanced at temperatures above 650 °C.
