Austenite Grain Growth Kinetics in API X65 and X70 Line

The materials used for this experimental work were API steel grades X65 and X70 with the chemical composition shown in Table 1. The steels were supplied by SABIC in the form of hot-rolled plate of 15 mm thickness. Specimens with dimensions of 20 mm × 10 mm × 10 mm were cut from the plate by diamond blade under coolant at low speed of 300 rpm 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.

Microstructural analysis and mechanical behavior of the

Mar 11, 2021 · This study aimed to investigate the heat-affected zone (HAZ) behavior in an API 5L X70 steel welded by the gas metal arc welding process (GMAW). In the steel welding processes, this region is very critical due to microstructural and allotropic transformations that affect the mechanical properties. Three samples were welded using a robotic arm with different welding speeds, thus obtaining three 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].
