EN8 Round Bar

Wide Size Range of Carbon Steel EN8 hex bar Manufacturer in India

Round bars and rods are made as per international standards and differ in qualities and specifications. Carbon Steel EN8 hex bar is one such bar that is made up of unalloyed low carbon steel. It displays good tensile strength and is available in sizes ranging between 16 mm to130 mm. These bars have moderate wear resistance by flame and induction hardening process. EN8 round bar manufacturers recommend these bars due to their excellent surface hardness and they also can be heat treated. They are said to be ductile and are used for engineering applications.

Alloy EN8 shaft can have a cold surface finish or smooth turned, peeled and turned, bright drawn, cold drawn, hot drawn, polished, and so on. They are heat preserved to provide excellent surface rigidity and moderate blaze resistance. The outer diameter of EN8 hollow bar sizes ranges between 6mm and 800mm. They are widely used in the electrical construction field, ships, military, and mechanical applications. Our team passes these products through various tests to ensure that they maintain desired properties. EN8 flat bars are even customized as per the requirements of our customers.

We use high quality raw material in manufacturing EN8 bright bar that is widely used in pumps, shafts, valves, hinges, and pins. We have evolved with time and our advanced technology helps us in developing economies of scale which in turn helps us in providing these EN8 square bars at affordable and competitive rates. Our customers trust us due to our time and damage free delivery. EN8 steel rods manufactured by us are distributed worldwide.
