1. Scope | ||||||||||
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. 1.3 The values stated in either SI
units or inch-pound units are to be regarded separately as
standard. The values stated in each system may not be exact
equivalents; therefore, each system shall be used independently of
the other. Combining values from the two systems may result in
non-conformance with the standard.
