1 Scope This Part of GB 150 specifies the designation and the standard of steels that may be used for the pressure components of pressure vessels, the additional technical requirements of steels, and the application scope (temperature and pressure) and allowable stress of steels. This Part is applicable to the pressure vessels with design temperature during -253℃~800℃ and design pressure no larger than 35MPa. Inapplicable scope of this Part: inapplicable scope specified in GB 150.1; vessels in refrigeration industry and papermaking industry; enamelled vessels and simple pressure vessels; scope specified in Article 1.4 of TSG R0004. 2 Normative References The following documents are absolutely essential to the application of this Standard. For dated reference documents, only the dated versions apply to this Standard; for undated reference documents, the latest versions (including all amendments) apply to this Standard.
