ASTM A451/A451M-14 Standard Specification for Centrifugally Cast Austenitic Steel Pipe for High-Temperature Service
standard by ASTM International, 11/01/2014
Full Description
1.1This specification2 covers austenitic alloy steel pipe for use in high-temperature, corrosive, or nuclear pressure service.
1.2Several 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 CPH10.1.3Optional supplementary requirements are provided when additional testing may be required.
1.4The 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.
1.4.1Within the text, the SI units are shown in brackets.
