4、 06/1 and 06/3. Amendments This standard differs from DIN EN 10302:2002-09 as follows: a) Steel grade 1.4951 has been added. The chemical composition of creep resisting steels 1.4922 (percentage by mass of P and S) and 1.4959 (percentage by mass of Al) has been modified. Within the framework of inte
5、rnational harmonization, the percentage by mass of nitrogen has been adjusted to N 30 longitudinal transverse aIn cases of doubt or dispute the gauge length shall be Lo= 5,65 0S for test pieces from products t 3 mm.
