Greek Ascoloy 418 stainless bar is a higher strength modification of the 12% chromium family of martensitic stainless steels. Greek Ascoloy retains corrosion and oxidation resistance and has usable strength and creep resistance to 1050ºF (566˚C). This grade is used for jet engine compressor blades and vanes due to resistance to stress corrosion cracking. Also used for discs in lower temperature turbine stages and for turbine diffuser components.
