Anotácia textu normy ASTM A451/A451M-20 :
This specification covers the standard for centrifugally cast austenitic alloy steel pipe for use in high-temperature, corrosive, or nuclear pressure service. The pipe shall receive a heat treatment at the required temperature and holding time followed by quenching in water or rapid cool by other means. The pipe shall be machined on the inner and outer surfaces and shall conform to specified roughness value. Heat and product analysis shall be done to determine the chemical composition and shall conform to the required carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, columbium, tantalum, and nitrogen contents. Hydrostatic and tension tests shall be performed and shall conform to the required tensile strength, yield strength, and elongation.

1.1 This specification2 covers austenitic alloy steel pipe for use in high-temperature, corrosive, or nuclear pressure service. 1.2 Several grades of austenitic stainless steel are covered as indicated in Table 1. 1.3 Optional supplementary requirements are provided when additional testing may be required. 1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. 1.4.1 Within the text, the SI units are shown in brackets. Note 1: This specification is not intended to cover
centrifugal pipe made from alloys containing more than 0.20 %
carbon, such as are covered by Specification A297/A297M.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
