ASTM A890\/A890M-12<\/h3>\n

Historical Standard: Standard Specification for Castings, Iron-Chromium-Nickel-Molybdenum Corrosion-Resistant, Duplex (Austenitic\/Ferritic) for General Application<\/h4>\n
\n

ASTM A890\/A890M<\/h4>\n

Scope<\/strong><\/p>\n

1.1 This specification covers a group of cast duplex stainless steels (austenitic\/ferritic).<\/p>\n

1.2 The duplex stainless steel alloys 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 alloys 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.<\/p>\n

Note<\/span> 1\u2014Because of the possibility of precipitation of embrittling phases, the grades included in this specification are not recommended for service at temperatures above 600\u00ba<\/span>F [315\u00ba<\/span>C].<\/p>\n

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.<\/p>\n

1.3.1 Within the text, the SI units are shown in brackets.<\/p>\n
