Specification for Castings, Iron-Chromium, Iron-Chromium-Nickel, Corrosion-Resistant, for General Application

ANSI/ASTM A743/A 743M-1998 发布历史

This specification covers iron-chromium and iron-chromium-nickel alloy castings for general corrosion-resistant application. The grades covered by this specification represent types of alloy castings suitable for broad ranges of application which are intended for a wide variety of corrosion environments. Note 1-For alloy castings for severe corrosion-resistant service, reference should be made to Specification A744/A744M. For general heat-resistant alloy castings, reference should be made to Specification A297/A297M. For nickel alloy castings for corrosion-resistant service, reference should be made to Specification A494/A494M. 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 A743 and SI units for material ordered to Specification A743M.
