These test methods describe laboratory tests for comparing the resistance of stainless steels and related alloys to the initiation of pitting and crevice corrosion. The results may be used for ranking alloys in order of increasing resistance to pitting and crevice corrosion. These test methods cover procedures for the determination of the resistance of stainless steels and related alloys to pitting and crevice corrosion (see Terminology G 15) when exposed to oxidizing chloride environments. Method A—Ferric chloride pitting test. When using stainless and duplex steels, ASTM G48 is widely used to ensure the quality of the material and resistance to pitting and crevice corrosion. ASTM G48 Methods A-F: Which test do I need? Method C—Critical pitting temperature test for nickel-base and chromium-bearing.

The ASTM GA test (ferric chloride test) is widely used for pre-qualification of corrosion resistant alloys, welds and weld overlays for oil and gas industry. Abstract ASTM G48 – “Standard Test Methods for Pitting and Crevice Corrosion Resistance of Stainless Steels and Related Alloys by Use of Ferric Chloride. ASTM G48 - Download as PDF File .pdf), Text File .txt) or read online.

Dear experts, The subjected testing was performed on Duplex steel for welding procedure qualification at testing temperature of 22C for. Fig. 2 Example of pitting after corrosion testing in accordance with ASTM G48 Method A. The test temperature of 22 °C is too aggressive for lean duplex grades . 1 These test methods are under the jurisdiction of ASTM Committee G01 on. Corrosion Results for ASTM G48 Standard Test Method for Pitting and Crevice. My duplex or superduplex stainless steel WPQ has failed ASTM G48 testing FAQ: Do ASME/ASTM standards allow the use of optical enhancement (e.g. 24 Dec "The test temperatures given in the ASTM G48 standard are only recommendations, and the required test temperature will be given in the.

29 Nov Can we use the ASTM G48 test to establish the maximum allowable temperature of a metal or alloy in an oxidizing environment like seawater?. Key variables in the ASTM G48 ferric chloride pitting corrosion test have been studied, with emphasis on ways of making the test more reproducible for weld. 13 Feb ASTM G48 Test Method for Pitting and Crevice Corrosion Resistance of Stainless Steels and Related Alloys by use of Ferric Chloride Solution. The ASTM G48 standard is widely applied for pre-qualification of corrosion resistant alloys, welds and weld overlay within the oil and gas industry ( Mathiesen et.
