ASTM A105 Carbon Steel Round Bars
Carbon Steel UNS K03504 Round Bar, ASTM A105 Bars, SA 105 Round Bar, ASTM A105 Carbon Steel Round Bars, Carbon Steel A105 Bar, ASTM A105 Carbon Steel Black Bars Suppliers in Mumbai, India.
Leoscor Alloys is a recognized supplier of ASTM A105 Carbon Steel Round Bars, which have excellent features, such as Rustproof, Longer functional life, Minimum maintenance, etc. These SA 105 round bars cover standards for forged carbon steel piping components, that is, flanges, fittings, valves, and similar parts, for use in pressure systems at ambient and higher-temperature service conditions. Although this specification covers some piping components machined from rolled bars and seamless tubular products, it does not cover raw materials produced in these product forms. Alloy A105 Round Bars is a low carbon, manganese and silicon-containing steel similar to AISI 1330, but with lower manganese content. Typical UNS K03504 Round Bars applications include Petrochemical, Power Generation, Refineries, Combustible liquids and gases, Nuclear station pipelines, Heating system pipelines, General purpose pipelines, Vessels manufacturing, and more. If you're looking to buy ASTM A105 Round Bars or are searching for an SA 105 round bar equivalent, you can find them at an affordable price from Leoscor Alloys.
