適用范圍：This part of ISO 9328 specifies the requirements for flat products for pressure equipment, made ofthermomechanically rolled weldable fine grain steels as specified in Tables A.1 and B.1. The steels are notsuitable for hot forming.Until now, no sufficient data for the standardization of the elevated temperature properties of these steels areavailable. If their use at such temperatures is intended, the conditions for this are specially agreed uponbetween the interested parties.The requirements and definitions of ISO 9328-1 also apply to this part of ISO 9328.NOTE 1 Fine grain steels are understood to be steels with a ferritic grain size of 6 or finer when tested in accordancewith ISO 643.NOTE 2 This part of ISO 9328 offers the possibility of specifying products in accordance with European design codesand ASME-type design codes.
