Effect of Acicular Ferrite and Bainite in API X70 Steel Jul 18, 2020 · The mechanical properties obtained by the HT are higher than X100 steel. HT-30 min improve the corrosion resistance of X70 steel exposed to both solutions, which are related to coarse and homogeneous microstructure of AF and B. Localized corrosion was observed in the steel
Effect of manganese content and microstructure on the susceptibility of X70 pipeline steel to hydrogen cracking . Abstract . The influence of composition and microstructure on susceptibility to hydrogen induced cracking (HIC) was investigated in high strength pipeline steels, with Mn contents of 1.2% (standard, X70), and 0.5% (medium, MX70).
Effect of microstructure and composition on hydrogen pipeline steels having different compositions, namely standard X70 (1.2 % Mn) and medium X70 (0.5% Mn). Samples were investigated from the transfer bar and hot rolled strip stages of

Abstract:Considering the mechanical properties of X70 pipeline steel after repeated welding heat cycles, preheating and interpass temperature controlling are often adopted in the welding technology, which widely increase the welding construction time and lower the construction efficiency, thus improve the construction cost of pipelines.Grade X70 - an overview ScienceDirect TopicsAt the time, X70 grade steel pipes with diameters as large as 48" with 0.461" wall thickness were being used. The industry chose to wrap the steel pipes with isopolyester resinglass fiber composite. The selected GFRP offers high mechanical and corrosion resistance properties and
