EN31 Round Bars, AISI / SAE EN31 Round Bar manufacturer, EN31 Rods Supplier, Dealer, Stockiest
We are EN31 Round Bar manufacturers and we are only manufacturing from prime quality billets and blooms. The range of EN31 Round Bars which we manufacture for our customers are of high quality and these round bars are used for making machineries and OEM Auto components. These products have been made keeping in mind the quality parameters which have been set by the industry in the market. EN31 Round Bars are always supplied with the test certificates and can be supplied in bulk quantity as well as retail quantity as per customer’s requirements. EN31 alloy Steel round bars are supplied by us to various industries.
EN31 is a very high strength steel alloy which is hardened and tempered before supplying and has nickel, chromium, molybdenum making it high tensile steel strength, with good ductility and wear resistance. With relatively good impact properties at low temperatures, EN31 is also suitable for a variety of elevated temperature applications. EN31 round bars have good internal strength and high external strength, which makes it highly wear resistant. EN31 steel round bars offer good combination of ductility, strength and wear resistance. EN31 is a very high strength alloy engineering steel.
