AISI 1018 Carbon Steel Round Bar is made up of carbon steel with carbon, chromium, manganese, molybdenum, phosphorus, sulfur and silicon in its composition. Navstar Steel is a leading manufacturer and supplier of the AISI 1018 Carbon Steel Round Bar products in various scales and types. The bars come under the specifications AISI 1018 and ASME SA1018. The dimensions vary according to the EN, DIN, JIS, ASTM, BS, ASME and AISI standards.
They range from 100mm to 1200mm in size with lengths varying up to 12m. The Hot Rolled SAE 1018 Rod can also come in different finishes and forms. The forms can vary as round, square, hex, rectangle, billet, ingot, forging and flat forms whereas the finishes can be bright, polish and black. The 1018 Cold Rolled Steel Flat Bar is drawn under cold or room temperature conditions. The cold drawn bars are smoother and are used in most outdoor and aesthetic application types.
The AISI 1018 Square Bar is used for its strength. The material has 675ksi minimum tensile strength and 400ksi minimum yield strength. The material is also hard with a 229BHN score. The material is tough, durable and hard. Therefore it is used in applications that require high strength, high temperature operation and high hardness. The AISI 1018 Carbon Steel Bright Bar is used mostly in the pulp and paper industry and in the ship building industries for its smooth finish, corrosion resistance, toughness and hardness. The different geometrical shapes also play a major role in determining the strength of the bars. The Carbon Steel Round Bar is used in this manner to provide the maximum benefit of the geometrical shape’s strength. Please contact us for more information on these bars and rods and their prices.
