1. Scope | ||||||||||||||||||||||
1.1 This specification covers steel castings for valves, flanges, fittings, and other pressure-containing parts intended primarily for low-temperature service. 1.2 Several grades of ferritic steels and
one grade of martensitic steel are covered. Selection of analysis
will depend on design and service conditions (Note). The
temperature shown is the lowest temperature at which the material
ordinarily is required to meet the impact requirements of this
specification (see Supplementary Requirement S22, Impact Test
Temperatures). Users should note that hardenability of some of the
grades mentioned may restrict the maximum size at which the
required mechanical properties are obtainable (see Appendix
X1).
Note 1—This specification covers the low-temperature requirements particularly pertinent for ferritic and martensitic steels. Certain of the grades of austenitic steel castings furnished in accordance with Specification A351/A351M have been found suitable for low-temperature service down to −300°F [−184°C] and others down to −425°F [−254°C]. These grades may be used when impact tested in accordance with Specification A352/A352M with energy levels and temperatures of test mutually agreed upon between the purchaser and the manufacturer. As a guide to the selection of energy levels and testing temperatures, Appendix X1 should be consulted. 1.3 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. Inch-pound units are applicable for material ordered to Specification A352 and SI units for material ordered to Specification A352M. |
