API 5L X70 is a steel grade of API 5L which specifies the manufacture of two product levels (PSL1 and PSL2) line pipe. WLD Steel also provides internal & external coating like Black paint, varnished, FBE coating, 3LPE coating and all lined pipe on steel pipes as per the customers requirement. WLD steel supply and manufactured a large inventory of API 5L X70 steel pipe in PSL1 and PSL2. API 5L X70 Pipe Specifications - OctalsteelThe 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.

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. These Carbon Steel API 5L X70 PSL 1 Seamless Pipes are manufactured with micro-alloyed steel using elements such as
Apr 28, 2021 · CCT diagram (figure 12) of CGHAZ for API X70 steel was deduced from the result of dilation analysis, microstructure and hardness. Transformation start temperatures for ferrite, pearlite, bainite and martensite were determined by JMatPro software using chemical composition . In the present study, the major transformation occurred between 431 and 710 °C.

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 . 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 .
