x70 steel properties

Grade X70 an overview ScienceDirect Topics

At 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 API 5L X70 Pipe Specifications OctalsteelAPI 5L X70 steel pipe has a minimum yield strength of 70,300 psi or 485 Mpa. The current X70 steel pipe are all controlled micro alloyed carbon manganese steels. The micro alloys elements are mainly Nb, V and Ti, and the total content of micro alloys does not exceed 0.15%. Therefore, the structure of the pipe is composed of acicular ferrite and bainite, and it generally has good welding performances.API 5L X70 BEBON steelX70 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.

X70 steel plate/ pipes is one mainly of Steel for large diameter pipes ,API X 70 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 .Microstructure and Properties of Low Manganese API X70 The microstructure of thermomechanically processed X70 pipeline steel primarily consisted of acicular ferrite (AF) together with small fraction of polygonal ferrite (PF), degenerated pearlite (DP) and martensite/austenite (M/A) constituent. The AF predominant microstructure is fine, homogeneous and free of band structure of hard phase.Mechanical and Metallurgical Properties of Grade X70 Steel STEEL MANUFACTURING Alloy design concept of API X80 Low grade steel, API X70, has a polygonal ferrite pearlite microstructure.
