1 Jul Designation: G 28 – 02 Standard Test Methods of Detecting Susceptibility to Intergranular Corrosion in Wrought, Nickel-Rich, Chromium-Bearing Alloys1 This standard is issued under the?xed designation G 28; the number immediately following the designation indicates the year of original adoption or. ASTM G 28 Standard - Standard Test Methods for Detecting Susceptibility to Intergranular Corrosion in Wrought, Nickel-Rich, Chromium-Bearing Alloys. The ASTM G28, Method B test (23% H2SO4+ % HCl + 1% FeCl3 + 1% CuCl2 at boiling temperatures for 24 hours) was developed in the 's to detect susceptibility to intergranular attack more accurately than Method A for alloy C- and comparable alloys, as the high general corrosion rates of method A masks the.

The ASTM A method B and ASTM G28 method A tests are the same, except for their duration. ASTM G28 lists alloys and specifies the test exposure for each. It is mostly hours, but some alloys (such as C (UNS N) have a test exposure of 24 hours, because of the high corrosion rates found in this solution.

WELDING MATERIAL: ALLOY TEST PROCEDURE. Three samples were provided for testing. The flat surfaces were then ground to a grit finish and the welds were glass bead blasted to.

Intergranular Attack Susceptibility For Nickel Alloys. A While the ferric sulfate-sulfuric acid test does detect susceptibility to inter- granular corrosion in Alloy N, the boiling 65 % nitric acid test, Practices A , Practice C, for detecting susceptibility to intergranular corrosion in stainless steels is more sensitive and should be used if the intended service is nitric acid. Corrosion resistance. The investigations were concentrated essentially on the intergranular corrosion resistance of alloy B in different annealed and annealed and aged conditions. The specimens were tested using the standard ASTM G 28 A procedure (boiling aqueous solution of 50 % sufuric acid and ferric sulfate).
