In this work, the chemical composition and mechanical properties of high-Nb X80 grade steel pipes with a diameter of 1,219 mm and a wall thickness of 22 mm, which are coiled by steels API 5L X100 PSL2 Seamless Pipe X100 Grade Steel Pipe The chemical composition is based on 12 types of materials which are C, Si, Mn, P, S, Cu,Ni, Cr, Mo, Nb, Ti and Al. Its yield strength is 769 MPa and tensile strength is 823 MPa. The ratio of yield to the ultimate tensile strength is 0.93.

EN 10208 Steel pipes for pipelines for combustible fluids

EN 10208 Steel pipes for pipelines for combustible fluids are used for transporting gas, oil, combustible fluids with specific pressure in the mining, chemical, and power engineering industry. The pipes are manufactured with the diameters between 21,3 660 mm and with the wall thickness of up to 40 mm in the case of hot rolled seamless pipes First X80 Pipeline Section in Italy002 18.9 1222.1 L555MB 201 14.3 HKM / MRM b) Chemical composition C Si Mn P S Al Cu Cr Ni Mo V Nb Ti CE IIW Max. 0.10 0.35 2.00 0.020 0.003 0.050 0.10 0.10 0.10 0.25 0.01 0.06 0.03 0.45 properties Mechanical Properties The chemical composition (max values) and mean mechanical properties of the pipes are summarised in Table 1.

  • AbstractIntroductionExperimental Materials and ProceduresResultsDiscussionConclusionConflicts of InterestAuthors ContributionsImpact toughness of the weld metal is one of the important factors affecting the quality of hot bends, which is strongly dependent on the microstructure transformation during hot bending and tempering. In this study, three kinds of weld metals with different Ni contents were selected, and then the effects of tempering temperature on the microstructure impact toughness of weld metals for hot bends were investigated by simulation conducted on a Gleeble-3500 thermal simulator.
