Principal Design Features		A 105 is an ASTM specification dealing with forged carbon steel piping components. The steel alloy involved is a low carbon, manganese and silicon containing steel similar to AISI 1330, but with lower manganese content.

Applications		This ASTM specification covers carbon steel forgings for piping applications such as flanges and fittings

Machinability		Machinability is good as for any of the low alloy steels.

Forming		This specification covers forming by forging only.

Welding		The steel covered by this specification is weldable. Weld procedures used must be qualified with Section IX of the ASME Boiler and Pressure Vessel Code.

Heat Treatment		Heat treatment is not required except for flanges or piping components as called out in ASTM A 105/A section 5.1. When heat treatment is required it consists of normalizing at 1550 to 1700 F and air cooled. Quenching direct from the forging heating shall be followed by a temper at 1100 F and air cool.

Forging		This is a forging alloy that would be forged at temperatures in the range of 2200 to 1700 F followed by quenching and tempering or normalizing.

Hot Working		See "Forging".

Cold Working		This specification does not cover cold working other than machining.

Annealing		Annealing may be done by first allowing the forged parts to cool to below 1000 F and then reheat to between 1550 and 1700 F followed by slow furnace cooling.

Aging		Not applicable.

Tempering		Tempering is done at 1100 F followed by air cooling.

Hardening		See "Heat Treatment" and "Tempering".

Other Comments		Physical and mechanical properties are similar to those for AISI 1330 steel. Consult ASTM A105 for requirements as to strength and hardness.
