The Influence of Sulfur Concentration Below 0.006%

This work was conducted to look at the Charpy V -notch shelf energy achievable in TC128 Grade B steel with reduced sulfur content (0.006% max) and sulfide shape control.Transverse Charpy V -notch data have been c ollected from TC128 Grade B plates with sulfur levels ranging from 0.001% to 0.006% that have been calcium treated for shape control.Some results are removed in response to a notice of local law requirement.For more information,please see here.12345NextImpact testing in tanks for the API 653 exam - ApiexamApr 12,2015 unanchored tanks Minimum Charpy V notch Requirements for Plate Specimens#0183;For a new tank,if required by the Purchaser or if the material falls in an area other than safe for use,a set of Charpy V-notch impact specimens shall be taken from plates after heat treatment (if the plates have been heat treated),and the specimens shall fulfill the stated energy requirements.Three specimens are needed,and the Revisions to App Q and R to Coordinate with New APIQ.2.2.2 Impact testing of plates,including structural members made of plate,shall comply with the following a.Impact test specimens shall be taken transverse to the direction of final plate rolling.b.Charpy V-notch specimens shall be cooled to a temperature of 320 unanchored tanks Minimum Charpy V notch Requirements for Plate Specimens#176;F for A 353,A 553,and A 645 steels for impact testing.b.
