Tronixalloy.com is a leading manufacturer, stockist, supplier, and exporter of EN9 Round Bar. Normalised carbon steel grade en9 round and hex bar is well suited to engineering applications. The EN9 Round Bar is typically used in applications that require high tensile strength and superior wear resistance.
Typical applications for the en9 bright flat bars include its use in the production of shafts, axes, woodworking, crankshafts, knives, bushes, screws, springs, sprockets, cams, cylinders, sickles, machine tools, drills as well as small gears, keys and hammers. It is possible to produce welding rods for EN9 either in full lengths or cut to meet customer specifications.
These EN9 Round BarEN9 Round Bar are largely exported to countries like UAE, Australia, South Africa, Iran, Iraq, Qatar, Oman, Sri Lanka, Bahrain, Kuwait, Saudi Arabia, Europe in exact sizes needed by our buyers.
A round bar made of EN9 is also known as a round bar made of 070M55. The carbon content of an en9 bright bar ranges between 0.5 – 0.6%, making it a medium carbon steel alloy. A tensile strength of 500 to 800 MPa can be achieved with the EN9 steel rod.
EN9 Round Bars are commonly supplied as rolled. Because the alloy can be hardened by either a flame or an induction process, it has a high surface hardness value. Thus, en9 black bars have a hardness value of 180 HB to 230 HB. As a carbon steel alloy, en9 square bar exhibits excellent wear resistance properties. Due to its low alloying cost, EN 9 material rates are lower than some stainless steel grades. To view the en9 material price in India, click here.
