Kalikund Steel & Engineering Company (KSEC) is a prominent manufacturer, supplier, and distributor of AISI 4130 Hollow Bars. A hollow bar is a type of metal bar which is always round in shape and looks like a pipe or tube, but it has thicker walls. Our AISI 4130 Hollow Bar has the strength of a solid round bar, but since there is not center point, the weight per foot is less which makes it a cheaper option without compromising on strength. AISI 4130 steel is a medium carbon, low alloy steel containing molybdenum and chromium as its strengthening agents. With its low carbon content, AISI 4130 offers exceptional welding ability. Due to its excellent high temperature and high pressure resistance property, AISI 4130 Hollow Bars is used in manufacturing of Choke & Kill manifolds including Control Panel, Mud Manifolds, Cement Manifolds and Mud / Gas Separator.



The AISI 4130 Hollow Bars ranges from outside diameter 32 to 272 mm i.e. 1.26 to 10.57 inches. At Kalikund Steel & Engineering Company (KSEC) we also make different sizes as per customer demands. The AISI 4130 Hollow Bar also finds its applications in various commercial and industrial areas like Subsea Wellhead, Well head equipments, Christmas Tree Equipments, Oil & Gas, Oil Exploration, High Pressure Jobs, Drilling Equipments, Onshore offshore drilling and so many more. We offer the best services to our customers and see to it that products offered are of high quality.
