ASTM A36 is a structural quality mild steel. A36 carbon steel’s strength, formability, and excellent welding properties make it suitable for a large variety of applications, including welding, fabricating, and bending. In fact, A36 is the most commonly sold steel for structural steel fabrication applications and it has been in use since it was first issued in 1960. A36 Steel is available from Alro Steel in angles, flats, plates, and sheets. A36 steel is also available as SBQ (Special Bar Quality) and P&O (Pickled and Oiled).
About Hot Rolled Carbon Steel (SBQ)
Hot rolled carbon bars are often referred to as “SBQ” or "special bar quality," and are known for their superior mechanical properties over commodity grades of merchant bar. The products are made to specific chemistry and mechanical properties ranges, allowing them to be used in engineered applications. Resulting shafts, axles, and gears can be used in the automotive industry and agriculture equipment.
Yield strength of A-36 (36,000 psi) is less than that of cold roll C1018, thus enabling it to bend more readily than C1018. A36 carbon steel can also be galvanized to provide increased corrosion resistance.
