x70 steel properties

steel-plate-sheetAPI 5L X70 - BEBON steel

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 microstructure offers an excellent combination of strength and toughness.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 isX70 Steel Scientific.NetAbstract 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.Specified Minimum Yield Strength - an overview Steel may be grouped according to strength level and welding characteristics as follows Group I designates mild steels with specified minimum yield strengths of 40 ksi (280 MPa) or less.The carbon equivalent is generally 0.40% or less,and these steels may be welded by any of the welding processes as described in AWS D1.1.
