Jul 25, 2013 · Detailed mechanical and microstructural characterization was carried on 24mm thick ArcelorMittal X80 coils in order to identify the microstructure control required to reach high toughness as determined by the shear fracture appearance after DWTT testing. Evenmatched FCAW Process in API 5L X80 Steel The base metal used in this study was API 5L X80 pipeline steel, conformed by the UOE process, with a nominal diameter of 864 mm (34 ), thickness of Microstructural characterization Mechanical properties of tubular wire in the condition as welded (AWS A5.29). Induction bends in material Grade X80:experience In order to achieve and guarantee the specified mechanical-technological properties for high strength material as X80 (L555M), all bends undergo a post bent heat treatment. For large diameter pipes this is usually limited to a full body temper heat treatment. But if necessary, bends can also be full body quenched in a large water basin, as
Jun 08, 2017 · Table 1 shows the chemical composition of the X80 pipeline steel used in this research. The pipeline had an outside diameter of 1218 mm and a thickness of 22 mm. The tensile strength was 705 MPa, the yield strength of the base metal was 595 MPa, and the tensile elongation was 24%. Measurements of the Thermophysical Properties of the API The thermophysical properties of API 5L X80 steel were experimentally measured, in order to use these in computational models to determine the temperature field in welded joints.
