CONTAINED IN VOL 01.02, 2002 Covers austenitic-ferritic (duplex) stainless steel castings for valves, fittings, flanges and other pressure-containing parts. The stainless steels give combined enhanced mechanical properties and corrosion resistance when properly balanced in composition and properly heat treated Ferrite levels which are not specified, These grades will develop a range of approximately 30 to 60 % ferrite with the balance austenite.

1.1 This specification covers austenitic-ferritic (duplex) stainless steel castings for valves, flanges, fittings, and other pressure-containing parts.

1.2 The duplex stainless steels offer a combination of enhanced mechanical properties and corrosion resistance when properly balanced in composition and properly heat treated. Ferrite levels are not specified, but these grades will develop a range of approximately 30 to 60 % ferrite with the balance austenite. It is the responsibility of the purchaser to determine which grade shall be furnished depending on design and service conditions, mechanical properties, and corrosion-resistant characteristics.

Note 1 - Because of the possibility of precipitation of embrittling phases, the grades included in this specification are not recommended for service at temperatures above 600 degrees F. (315 degrees C).

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.
