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.
|
|
|
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.
