ASTM Vol.01.02 (2023)
This specification covers alloy steel castings that have been subjected to special heat treatment for valves, flanges, fittings, and other pressure-containing parts (Note 1) intended primarily for high-temperature service.
The high-temperature properties of the materials covered in this specification are dependent upon special heat treatment that is required. Although the high-temperature properties are not specified, they are implied by control of chemistry, heat treatment, and room-temperature properties.
Two grades of ferritic alloy steel are covered (Note 2). Selection will depend on the design and service conditions, mechanical properties, and high-temperature characteristics.
