Therefore, the aim of this study was to investigate the effect of microstructure and composition on hydrogen permeation in X70 pipeline steels. Permeation studies were performed on two pipeline steels having different compositions, namely standard X70 (1.2 % Mn) and medium X70 (0.5% Mn). Effects of Microstructure on Corrosion of X70 Pipe Steel Aug 25, 2008 · The test coupons were fabricated from a sheet of X70 pipe steel, supplied by Bao-Steel Co., China, with a chemical composition (wt.%):C 0.045, Mn 1.48, Si 0.26, S 0.001, P 0.017, Ni 0.16, Cr 0.031, Mo 0.23, Nb 0.033, Cu 0.21, and Fe balance.
chemical compositions of the X-grade steels are fairly simple, with maximum limits on C, Mn, S, P and other elements such as niobium and vanadium . The variations in strength (e.g., between X70 and X80) do not result primarily from variations in alloy composition, but from variations in the processing route of the steel . Prediction of mechanical properties of welded steel X70 Sep 01, 2020 · The developed model is designed to incorporate the chemical composition of API X70 steel as key input data and to predict multiple tensile and impact properties such as, YS, UTS, UTSw, EL, YTR, and CVN (BM, FZ, HAZ) as outputs. Thus, it offers a perception of the functional behavior of neural networks in the case of multiple output predictions.
The objective of this work was to study the influence of titanium variations on the API 5L-X70 steel weld metal properties. The relationship between microstructure and toughness of the weld deposit was studied by means of full metallographic, longitudinal tensile and Charpy-V notch tests on the specimens cut transversely to the weld beads.
