One of the original purposes of this compilation was to preserve "for the record" a listing of alloys that are no longer in production, and also to include the promising new alloys that have reached the experimental application stage of development Therefore, this compilation includes, in addition to production superalloys, some non-current and developmental alloys These alloys are identified whenever possible However, many of the older alloys listed are undoubtedly non-current, but they have not been so designated because the positive knowledge of such designation is not available to the author The data tabulated in this compilation have been gathered from all possible sources, but primarily from a direct solicitation of the producers The chemical compositions given are, for the most part, based on the mid-point of the specification range However, the compositions should be considered as approximate and are indicated in the table as "nominal chemical composition" Usually, the rupture properties listed are the average values for the normal form (bar, sheet, forging, etc.) and condition of processing and heat treatment When available, rupture strengths for other than the "normal condition" also have been included in this revision Because creep and rupture strengths of superalloys are as dependent upon processing and heat treatment as they are upon chemical composition, it is recommended that data in this compilation not be used for design purposes The data are intended to give only a rough idea of the relative strengths of the various alloys The alloy producers will be glad to supply the latest processing and heat-treatment information as well as physical properties and other technical data for their alloys Most of the alloys listed are proprietary, and many are manufactured by several alloy producers, under license agreements The producers of these alloys are not listed in the present document, but they may be found in ASTM Data Series Publication DS-45, "Compilation of Trade Names, Specifications, and Producers of Stainless Alloys and Superalloys", November, 1969 The age-hardenable stainless steels have been listed under a subheading in Group This was done primarily because their rupture strengths fall within the same temperature range as those for the Group alloys Another reason for placing the agehardenable stainless steels in Group is that they are ferritic (martensitic) in the aged condition, although they may be martensitic or austenitic as annealed The 1000-hour rupture strengths for selected iron-, nickel-, and cobalt-base superalloys are given in Figures 1, 2, and to display the range of strengths that can be expected from these alloys Some data from non-current alloys have been included in these figures For instance, in Figure 1, the strongest alloy (Unitemp 212 to 1400 F and CRM 6D from 1400 to 1600 F) demonstrate the strengths that are possible in iron-base alloys, even though these particular alloys are not being produced Another non-current iron-base alloy, AF -71, is of interest because it does not contain nickel Figure shows a comparison of the 1000-hour rupture strength ranges for the iron-, nickel-, and cobalt-base superalloys and includes data for the nickel-base developmental alloy TRW-VI A and a forecast of the 1000-hour rupture strength to be expected by about 1978 The pertinent ASTM and AMS specifications are given in the first table, which also lists the AlSIJnumbers that have been assigned Also, a listing of trade names and proprietors has been included
