标准范围

ISO 9328-5:2018规定了表A.1和B.1中规定的由热机轧制可焊接细晶粒钢制成的压力设备扁平产品的要求。这些钢不适合热成型。到目前为止，还没有足够的数据来标准化这些钢的高温性能。如果打算在这样的温度下使用，相关方应特别约定使用条件。ISO 9328-1的要求和定义也适用于本文件。注1:根据ISO 643进行试验时，细晶粒钢被理解为铁素体晶粒尺寸为6或更细的钢。注2:本文件提供了根据欧洲设计规范和ASME型式设计规范指定产品的可能性。

ISO 9328-5:2018 specifies the requirements for flat products for pressure equipment, made of thermomechanically rolled weldable fine grain steels as specified in Tables A.1 and B.1. The steels are not suitable for hot forming.Until now, no sufficient data for the standardization of the elevated temperature properties of these steels are available. If their use at such temperatures is intended, the conditions for this are specially agreed upon between the interested parties.The requirements and definitions of ISO 9328？1 also apply to this document.NOTE 1 Fine grain steels are understood to be steels with a ferritic grain size of 6 or finer when tested in accordance with ISO 643.NOTE 2 This document offers the possibility of specifying products in accordance with European design codes and ASME-type design codes.
