ASME BPVC 2023 Section II part A-1

New product

SA-352/SA-352M ASME BPVC.II.A-2023
Standard Specification for
Steel Castings, Ferritic and Martensitic, for Pressure-
Containing Parts, Suitable for Low-Temperature Service
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 1This 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.
