Greek Ascoloy
Technical Data Sheet
Greek Ascoloy is a hardenable chromium-nickel-tungsten martensitic alloy. Greek Ascoloy is designed for use in highly stressed parts at temperature up to 1200ºF (649ºC). It obtains deep hardening and has superior creep strength, resistance to tempering and stress-corrosion cracking together with the properties of the standard 12% chromium grades of stainless steel.
