Suppliers and Manufacturer of Alloy 20 Round Bars / Alloy 20 Wires, which can be ultimate until numerous years relying up at the practice. UNS N08020 Round Bars has functions like Corrosion resistance, Suitable for extremely good business sewage discharge, High overall performance to inorganic acid, Corrosion resistant, Rust proof, Durable, Toughness, Easy installation, Abrasion resistant, and more. Apart from, oxyacetylene welding all conventional welding techniques can be used on the Alloy 20 UNS N08020 Rods without the need to pre-heat. The specification requires that the material used to produce the ASTM B473 UNS N08020 Rod is to conform to a certain set of requirements. We offer an extensive collection of qualitative Alloy 20 Round Bars/Rods to our esteemed patrons. We provide this alloy round Bars and rods in various shapes, sizes, types, grades, standards, classes, dimensions, thickness, etc as per the requirement of the client. Alloy 20 Round Bars & Wires has bright annealed or bright annealed and cold rolled grease, where ultra – bright finishes is used for decorative applications.

This alloy is a low carbon containing metal. Furthermore, the alloy has been stabilized by the addition of niobium to the chemistry of the DIN 2.4660 Flat Bar. Alloy 20 Wires is frequently used for Steel Gates & Windows, Structural and fabrication work, Road Side Railings, and more. Nickel-Alloy 20 Bars are made via way of means of the use of top- notch pleasant substances making sure wonderful float of liquefied and gaseous cloth with none leakage. The higher content of nickel in the alloy is what improves the high temperature behavior of the alloy 20 welding rod. While the Alloy 20 has better resistance to pitting as opposed to 304 grade stainless steel, this property is on par with grade 316L. The specification also makes provisions for the performance of both a chemical analysis and a tension test to be subjected to the Alloy 20 Round Bar. These alloy 20 round bars/rods are available in various finishes such as bright polished, black, rough turned, matt finish, etc. We also offer these AS Alloy 20 in customized sizes and thicknesses as per specific demands by our esteemed clients at market leading prices. Having true reasserts in numerous nations enables us take hold of the pleasant cloth in quick span, we deliver & manufacture Wires in numerous sizes and special finishes as consistent with consumer requirement.

ASTM B473 Alloy 20 Round Bar Weight Calculation Formula

  • ROUND – dia.mm2 x 0.004143 = Weight in lbs. per foot
  • ROUND – dia.mm2 x 0.006165 = Weight in kilograms per metre
  • HEXAGON – size mm2 x 0.00457 = Weight in lbs. per foot
  • HEXAGON – size mm2 x 0.006798 = Weight in kilograms per metre
  • SQUARE – Size mm2 x 0.00527 = Weight in lbs. per foot
  • SQUARE – Size mm2 x 0.000785 = Weight in kilograms per metre
  • U.K. tons per sq. inch (tons f/in2) x 15.4443 = Mega Pascals (MPa)
  • Newton per sq. milimeter (N/mm2) x 0.064749 = U.K. tons per sq. inch
  • Metres to feet x 3.2809
  • Feet to metres x 0.3048
  • Mega Pascals (MPa) x 0.64749 = U.K. tons f per square inch
