H = Hot rolled strip Mechanical Properties of Intercritically Annealed X80 Line Feb 17, 2021 · Feb 17, 2021 · Microalloyed low-carbon steels are used for line pipe applications as they combine high strength and acceptable fracture toughness with good weldability. During multi-pass welding, the strength and impact toughness of the material in the heat-affected zone (HAZ) is potentially degraded, in particular the regions where the thermal fields from multi-pass welds overlap (for Microstructure and Mechanical Properties of Two Api Steels Systematic investigation was carried out to understand the effect of plate-to-pipe forming (U-bending) strain on the microstructure and mechanical properties of X80 linepipe steel and to establish

What is Alloy Steel? Properties, Grades, Types of Carbon Steel

May 02, 2019 · Carbon Steel Pipes & Stainless Steel Seamless Pipes, Fittings, The mechanical properties achievable are dependent on the addition of elements such as nickel, chromium, molybdenum and vanadium. The following is a range of improved properties in alloy steels (as compared to carbon steels):strength, hardness, toughness, wears resistance Mechanical Properties of High-Nb X80 Steel Weld Pipes for

  • AbstractIntroductionSample Selection and Actual Manufacture Processes of Weld PipesResults of Statistical InvestigationDiscussionConclusionConflicts of InterestAuthors ContributionsAcknowledgmentsThe mechanical properties of steel pipe have great effects on the integrality and operation safety of gas transmission pipeline. In order to reduce the cost of the steel pipe, the high-Nb X80 pipeline steels with the different alloying systems have been used in the Second West-to-East Gas Transmission Pipeline Project. Nevertheless, an investigation into the effects of chemical composition on the mechanical properties of steel pipes is lacking. In this work, the chemical composition and mechaniHAZ Microstructure and Properties of Pipeline Steelsextent of the HAZ, and the corresponding changes in mechanical properties, depend on the plate thickness and the weld heat input, usually in the ranges 8 toaround 45 mm and <~3~ to >~10 kJ/mm respectively, with the lower end of this range being more typical of spiral welded pipe, where pipe wall thicknesses are generally lower, up to ~25 mm.
