METRIC EQUIVALENTSX1.1 The SI unit for strength properties now shown is inaccordance with the International System of Units (SI). Thederi
48、ved SI unit for force is the newton (N), which is defined asthat force which when applied to a body having a mass of onekilogram gives it an acceleration of one metre per secondsquared (N = kgm s2). The derived SI unit for pressure orstress is the newton per square metre (N/m2), which has beennamed
49、the pascal (Pa) by the General Conference on Weightsand Measures. Since 1 ksi = 6 894 757 Pa the metric equiva-lents are expressed as megapascal (MPa), which is the same asMN/m2and N/mm2.SUMMARY OF CHANGESCommittee B05 has identified the principal changes to this specification that have been incorporated since the2011 issue as follows:(1) Made editorial corrections to the standard to ensure itconforms to proper form and style.(2) Corrected the H04 max Tensile strength from 630 MPa to625 MPa as it was incorrect.B592
