BEBON steel is API 5L X70 steel supplier,we have much experience in manufacture API 5L X70 steel, We could give the fastest delivery time on the base of our competitive price directly from our mill. if you need know steel grade feature,we can provide API 5L X70 chemical composition and API 5L X70 mechanical properties. API X80 Grade Electric Resistance Welded Pipe with with the same composition as the base material. This means that the properties of the base material and weld of the pipe must be satisfied simultaneously by the com-position design of the hot coil used as the starting mate-rial. Therefore, in material design, first, the effects of the chemical composition and microstructure on the tough-

Carbon Steel Line Pipe Grades and Chart Specifications

We at Ashapura Steel are manufacturer, exporter and supplier of a qualitative range of Carbon API 5L X70 PSL 1 Line Pipes and API 5L X70 PSL 2 Carbon Steel Line Pipes in Mumbai, India, that is being designed as per the national and international standard quality standards. These Carbon Steel API 5L X70 PSL 1 Seamless Pipes are manufactured with micro-alloyed steel using elements such as Niobium, ium, Vanadium and low Carbon content, giving the steel Corrosion Performance of Carbon Steel in CO2 Aqueous The chemical composition of X70 carbon steel and test solution is shown in Tables 1 and 2. The specimens of 14 mm × 10 mm × 5 mm and 10 mm × 10 mm × 3 mm were used for immersion tests and electrochemical measurements, respectively.

Effect of Acicular Ferrite and Bainite in API X70 Steel

Jul 18, 2020 · Table 1 Chemical composition of API X70 steel (wt%) Full size table. The heat treatment was carried out according to the niobium content in the steel, this element is of special interest because the dissolution and precipitation temperature is the same for both cases (1050 °C) [ 34 ]. Effect of Chemical Composition on Quenching Hardness of In order to find the reasons of that the hardness of 1Cr17Ni2 stainless steel partial components after being quenched is weakened, based on the sampling analysis on the partial components to produces the components to carry on the sampling analysis, and to compare the contrast that the maximum of the hardness of quenched material is lower than (the average value of the hardness the Materials Free Full-Text Strengthening Effect of Nb on The test material is taken from an industrially produced X70 pipeline steel plate coil, and the thickness of the steel plate is 17.5 mm. The chemical composition of the material is (wt.%) 0.065 C, 0.20 Si, 1.55 Mn, 0.065 Nb, 0.016 P, and 0.0012 S.

Microstructure and Mechanical Properties of Two Api

The chemical compositions of the two steels used in the present study are shown in Tables 1 and 2. Comparing these results with the existing specifications for pipelines, it is verified that the steels satisfy the API requirements12. It should be noted the lower carbon content of X70 steel, compensated by the presence of microalloying additions. In PAPER OPEN ACCESS Mechanical Characterization of 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 [4]. 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 [4]. The Change in the Chemical Composition and Toughness of 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. The best combination of microstructure and impact


API 5L X70 steel plate/pipes, API 5L X70 steel plate/pipes, under API 5L standard, we can regard X70 steel plate/pipes as large diameter pipes. X70 steel plate/pipes is one mainly of Steel for large diameter pipes,API-X70 steel with the demands in mechanical properties of the pipes followed the API specification for grade X70 (YS is 485MPa, TS is from 600-750 MPa).It is well known that a low carbon bainitic
