Carbon Steel A105 Bars are made up of a mix of carbon (up to 0.35%), manganese (0.60–1.05%), phosphorus (max 0.035%), sulfur (max 0.040%), and silicon (0.10–0.35%). This low-alloy steel is known for its excellent machinability, weldability, and strength. When it comes to mechanical properties, it boasts a minimum tensile strength of 485 MPa, a yield strength of 250 MPa, and an elongation of 22% over 2 inches. With a Brinell hardness of around 187 HBW, A105 bars are perfect for moderate to high-temperature applications in pressure systems and piping.
These bars are popular across various industrial sectors thanks to their strength, toughness, and resistance to corrosion in mild environments. You’ll often find them in the fabrication of flanges, valves, fittings, and pressure vessels, especially in the oil & gas, petrochemical, and power generation industries. They’re particularly suited for high-temperature and high-pressure applications, whether in welded or seamless systems. A105 bars also find their place in heat exchangers, refineries, shipbuilding, and mechanical engineering. Their compatibility with forging and machining processes makes them a great choice for structural and mechanical components across a wide array of industries.
