Detrimental Intermetallic Phase in Duplex Ferritic Stainless Steels ASTM A923

Detrimental Intermetallic Phase in Duplex Ferritic Stainless Steels ASTM A923

The goal of these test methods, ASTM A923, is to determine the existence of intermetallic phases in duplex stainless steels that have a significant impact on toughness or corrosion resistance. The values given in inch-pound or SI units should be considered the standard.


    ASTM A923 test methods are used to detect a harmful intermetallic phase in duplex austenitic/ferritic stainless steel that significantly impacts toughness and corrosion resistance. Sodium Hydroxide Etch Test is used to classify Etch Structures of Duplex Stainless Steels, Charpy Impact Test for classification of Duplex Stainless Steel Structures, and Ferric Chloride Corrosion Test for classification of Duplex Stainless Steel Structures.

    Based on the recorded corrosion rate in comparison to the established acceptance criteria, the test result is reported as passed or failed.
