Principal Design Features		ASTM A516 specification covers plate of carbon steel for moderate and lower temperature use in pressure vessels. The Grade 60 alloy is basically the same as AISI steel 1330.

Applications		Used for weld fabrication of pressure vessels that require improved notch toughness for lower than ambient temperature service.

Machinability		machinability of Grade 60 steel is good, being the equivalent of AISI 1330 steel.

Forming		Forming capability is good as the steel has good ductility.

Welding		Grade 60 steel is intended for fabricating by welding. Thus its welding characteristics are good by conventional methods.

Heat Treatment		The steel is supplied in the as-rolled condition or as normalized or stress relieved annealed, as specified by the purchaser. Subsequent heat treatment is not covered by this specification. See also "Tempering".

Forging		Material is supplied as plate and not subsequently subjected to forging.

Hot Working		Grade 60 steel may be hot worked if necessary. Contact the steel supplier for information.

Cold Working		Cold works readily by bending an shaping as with the plain carbon steels.

Annealing		Annealing, if necessary, is done at 1600 F and slow furnace cooled.

Aging		Not applicable.

Tempering		Notch toughness can be improved by quenched cooling from hot rolling or normalizing by the supplier. If such a faster cooling rate is agreed upon between purchaser and supplier then the steel is also to be tempered at 1200 F.

Hardening		The steel hardens by cold worked and also can be heat treated and quenched for hardness. However this specification does not deal with heat treated material.

Other Comments		Grade 60 steel has a tensile strength in the 60 to 80 ksi range with 25% elongation. Its physical and mechanical properties are basically similar to AISI 1330 steel.
