AISI 1018 Carbon Steel Round Bar is expertly crafted from a blend of carbon steel enriched with carbon,
chromium, manganese, molybdenum, phosphorus, sulfur, and silicon. Amardeep stands out as a premier
manufacturer and supplier of AISI 1018 Carbon Steel Round Bar products, offering a diverse range to meet
various specifications. These bars adhere to the stringent standards of AISI 1018 and ASME SA1018, conforming
to dimensions outlined by EN, DIN, JIS, ASTM, BS, ASME, and AISI.
Spanning sizes from 100mm to 1200mm and lengths up to 12m, our Hot Rolled SAE 1018 Rods are available in
different finishes and forms. Shapes include round, square, hex, rectangle, billet, ingot, forging, and flat,
while finishes encompass bright, polished, and black. The 1018 Cold Rolled Steel Flat Bar undergoes a drawing
process under cold or room temperature conditions, resulting in smoother bars ideal for outdoor and aesthetic
applications.
The strength of the AISI 1018 Square Bar is unmatched, boasting a minimum tensile strength of 675ksi and a
minimum yield strength of 400ksi, with a hardness score of 229BHN. Recognized for its toughness, durability, and
hardness, this material finds application in scenarios demanding high strength, elevated temperature operations,
and exceptional hardness. The AISI 1018 Carbon Steel Bright Bar finds utility in the pulp and paper industry and
shipbuilding due to its smooth finish, corrosion resistance, toughness, and hardness.
The diverse geometrical shapes of these bars significantly contribute to their strength, with the Carbon Steel
Round Bar strategically employed to maximize the benefits of these shapes. For further details on these bars and
rods, including pricing information, we invite you to contact us.
