Our A105 bars are strong, long-lasting, and easy to work with. This makes them perfect for flanges, fittings, valves, and piping parts in oil & gas, construction, and industrial uses. Marzouk Steel focuses on getting it right and making sure our customers are happy. We offer reliable and affordable steel solutions that meet top industry standards for performance and last a long time.
Carbon Steel A105 Bars are mainly made of carbon (0.35% max), manganese (0.60-1.05%), phosphorus (0.035% max), sulfur (0.040% max), and silicon (0.10-0.35%) to exhibit very good strength and durability. They possess mechanical characteristics such as minimum tensile strength of 485 MPa, yield strength of 250 MPa, and elongation of 22%. They benefit from high machinability, good weldability, high toughness, and withstands high pressure and temperature. These make them a perfect match for structural, piping, and industrial uses.
