    Abstract

    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.

    This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

    1. Scope

    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.

    (A) Where ellipses (...) appear in this table there is no requirement, and the element need not be analyzed or reported.
    (B) Grades CPF10MC and CPF8C may have a columbium plus tantalum content maximum of 1.35 %.
    (C) No designation as yet assigned by ASTM International or Steel Founders' Society of America.
    (D) By agreement between the manufacturer and the purchaser, the carbon content of Grade CPH20 may be restricted to 0.10 % max. When so agreed, the grade designation shall be CPH10.

    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 non-conformance with the standard.

    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.

    1.4.1 Within the text, the SI units are shown in brackets.
