This ASTM specification covers low and intermediate strength carbon steel plates. Used for general purpose structural applications of medium strength  (60 ksi tensile) requirement. Machinability of the steel covered by this specification is good, as for any low carbon steel. Formability is good by conventional means, much the same as for 1030 plain carbon steel. The steel covered by this specification may be welded by conventional methods, Heat treatment consists of normalizing at 1650 F and slow furnace cool. This specification is for plate product form and does not include forging. Hot working of the plate steel may be done at 1650 - 1700 F or lower temperatures. The steel is readily cold worked by conventional methods. Anneal at 1550 to 1800 F and slow furnace cool. Properties of the steel covered by this specification are similar to AISI 1330 steel.  See ASTM A283 for mechanical property requirements.
