    Abstract

    The Subcommittee on the Properties of Weldments of the Data and Publications Panel of the ASTM-ASME Joint Committee on Effect of Temperature on the Properties of Metals accumulated data from laboratories conducting tests at elevated temperatures on welds. The original data were in the form of reports, technical papers and a questionnaire circulated by the subcommittee. These data have been reduced to a common type of data sheet and the key properties presented graphically as a function of temperature. The approximate ranges in properties for the unwelded forms of the alloys, as presented in prior Special Technical Publications of the ASTM, are shown to indicate the relative properties of welds and base metals. Data are presented for carbon, low-alloyed and austenitic steels and for a number of the complex alloys developed for high strength at high temperatures. Tensile, rupture and creep properties are covered by the data. The data sheets provided space for information on the welding methods and conditions, chemical composition of both base metal and weld deposit, heat treatments, hardness, and microstructural characteristics. Both original test data and derived creep and rupture strengths are shown on the data sheets. The source of data is acknowledged on each data sheet. In most cases only part of the data for which provision was made in the data sheets was available. Properties were reported for specimens taken entirely from weld-deposited metal as well as for cross-weld specimens which included both base metal and weld deposit in the gage section. In cross-weld specimens the weld deposit frequently differed in composition from the base metal; and in some cases two different base metals were present in the same weldment. Some data covered sheet specimens welded without filler metal.
