A36 steel

Structural steel standard

A36 steel is a common structural steel alloy used in the United States. The A36 standard was established by the ASTM International. The standard was published in 1960 and has been updated several times since. Prior to 1960, the dominant standards for structural steel in North America were A7 and A9. Note that SAE/AISI A7 and A9 tool steels are not the same as the obsolete ASTM A7 and A9 structural steels.
