Abstract
The results of some 5000 elevated temperature yield or proof stress tests on steels conforming to the new series of B.S. 1501 carbon steel plate specifications are reported. The data are discussed in relation to the levels of yield and proof stress specified in B.S. 1501: 1964 and the various factors causing variations in the elevated temperature properties are outlined.
The effect of differences in testing technique and in methods of deriving ‘guaranteed’ properties (i.e. minimum values which the steel in question will always meet) are considered in relation to the draft International Boiler Code and it is suggested that discrepancies in design thicknesses of approximately 10 per cent can arise owing to these differences.
