23、 METRIC EQUIVALENTSX1.1 The SI unit for strength properties now shown is inaccordance with the International System of Units (SI). Thederived 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 m

24、etre per secondsquared (N = kgm/s2). The derived SI unit for pressure orstress is the newton per square metre (N/m2), which has beennamed 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 t

25、he same asMN/m2and N/mm2.TABLE 1 Chemical Requirements Copper Alloy UNS No. C83600Major ElementsComposition, % max(Except as Indicated)Copper 84.086.0Tin 4.06.0Lead 4.06.0Zinc 4.06.0Nickel incl Cobalt 1.0AResidual ElementsComposition, % max(Except as Indicated)Iron 0.30Antimony 0.25Sulfur 0.08Phosph
