OFFICIAL TEST CERTIFICATE: issued by TUV - SGS - BV
TECHNICAL SPECIFICATION - Steel Grade Jethete M152
Jethete M152 is a creep and corrosion resistant, hardened and tempered steel with a usual upper temperature limit of 560°C. It combines very good toughness and creep rupture properties making it an excellent alloy for use in highly stressed turbine blades, discs, screws, bolts and rings. Jethete M152 is supplied by Aircraft Materials in both bar form, to British Standards BS S151 and BS S159 and in sheet form to Rolls Royce specifications MSRR 6504 and MSRR 6514. It can also be supplied in mill productions to the US Aerospace specification AMS 5719.
