METRIC EQUIVALENTSX1.1 The SI unit for strength prop
44、erties 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 metre per secondsquared (N = kgm/s2). The derived SI u
45、nit 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 metricequivalents are expressed as megapascal (MPa), which is thesame as MN/m2and N/mm2.SUMMARY OF CHANGESCommittee B0
46、5 has identified the location of selected changes to this standard since the last issue(B 936 041) that may impact the use of this standard. (Approved Oct. 1, 2008.)(1) Corrected typographical errors throughout the standard.(2) A definition that is now in B 846 was removed fromSection 4.(3) The TR T
47、emper designation was added in paragraph 8.1.2.(4) Mechanical Properties (paragraphs 10.1.1 and 10.1.2) wererevised to show that product furnished under this specificationwill conform to 0.2 % offset yield strength and not tensilestrength.(5) The Cr range was revised from 0.20 0.70 to 0.20 0.7 tobe
48、consistent with CDA.(6) Table 2 was revised to show it is for Yield StrengthRequirements, TR08 temper values were added, 0.2 % offsetyield strength values were added for all tempers, and the tensilestrength ranges were modified for TM04 and TM08 tempers.(7) Table 3 was revised to add TR08 temper, th
49、e electricalresistivity value was modified, and the electrical conductifityvalue was modified.ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentionedin this standard. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the riskof infringement of such rights, are entirely their own responsibility.This standard is subject to revision at any time by the responsible technical committee and must be reviewed every
