ASTM A567/A567M-84 PDF

This specification covers alloy castings for high-strength service at elevated temperatures (see Note 1). These iron-, cobalt-, or nickel-base alloys contain chromium and other strengthening elements. Compositions are given in Table 1. Selection will depend upon such considerations as design and service conditions (see Note 2).

Note 1 - Ferritic and austenitic steel castings for high-temperature corrosion-resistance service are covered by: Specification A297/A297M, Specification A351/A351M, Specification A743/A743M and Specification A744/A744M.

Note 2 - The committee formulating these specifications has included 19 grades of materials extensively used for the present purpose. Since these grades possess varying degrees of suitability for high-temperature and corrosion-resistant service, it is the responsibility of the purchaser to determine which grade will be furnished with due consideration having been given by purchaser to the requirements of applicable construction codes, if any.
