Hardening, which takes place in the range 788 ☌ to 816 ☌.Carburising, which takes place in the range 899 ☌ to 927 ☌.Normalizing, which takes place in the range 899 ☌ to 954 ☌.Heat TreatmentĪ36 steel can be hardened using a variety of heat treatment processes including: It is used in forming tanks, bins, bearing plates, fixtures, rings, templates, jigs, sprockets, cams, gears, base plates, forgings, ornamental works, stakes, brackets, automotive and agricultural equipment, frames, machinery parts. It is used in bolted, riveted, or welded construction of bridges, buildings, and oil rigs. It can be found in buildings, bridges, and other large-scale structures. Specification A36 Mechanical PropertyĪSTM A36 Carbon Structural Steel Plate Application fieldsĭue to the relatively good strength, the formability of A36 steel, and the fact that it can be easily welded, it is commonly used as structural steel. Japanese standard SS400, the tensile strength is 400~510 MPa, and the yield strength is 245Mpa. EquivalentĪmerican Standard A36, the tensile strength is 58~80 Ksi (about 400~550MPa), and the yield strength is 36 Ksi (about 250MPa).Įuropean standard S275, the tensile strength is 430~580 MPa, and the yield strength is >=275MPa.Ĭhinese standard Q235, the tensile strength is 370~500 MPa, and the yield strength is 235MPa. This means that when the ingot is at a high temperature, rollers are used to shape it to its final size. Once it reaches the chemical composition of A36 steel, it will solidify into a rectangular ingot. The impurities are removed, and alloying elements are added to the molten steel.
The manufacturing method of A36 is similar to most carbon steel.įirst, the iron ore and coal are mixed in the furnace. This allows A36 steel to be easily machined, welded, and formed, making it extremely useful as a general-purpose steel. Low carbon steel is classified as having less than 0.3% carbon by weight. This specification covers carbon steel shape plates, and bars of structural quality for use in riveted, bolted, or welded construction of bridges and buildings, and for general structural purposes.Ī36 is low carbon steel.
