ASTM A105 is the standard specification covering forged carbon steel piping components for ambient- and higher-temperature service in pressure systems. It can be readily manufactured to flanges, fittings, valves, and other piping components in accordance with dimensional standards such as MSS, ASME, API, EN/BS, DIN, NOSOK specifications, etc. A105 forgings are limited to a maximum weight of 4540 kg [10000 lb]. As stated in our quality manual, welding repair of defects in ASTM A105 flanges or fittings is absolutely prohibited by yaang(although it is permissible by the standard).
Forging
ASTM A105 carbon steel can be forged at temperatures in the range of 2200 to 1700 Fahrenheit (°F) followed by quenching and tempering or normalizing. The actual hot forging temperatures in closed die forging process will be decided by a number of factors, such as complexity of the forged part.
The proper temperature of forging can only be checked at the beginning of forging, higher temperature will probably cause surface defects, such as mill scales, which will bring uneven surface. And lower temperature will be not conducive to the plastic deformation of C1045 carbon steel forged part.
A105 forgings are limited to a maximum weight of 4540 kg [10000 lb]. As stated in our quality manual, welding repair of defects in ASTM A105 flanges or fittings is absolutely prohibited by yaang(although it is permissible by the standard).
Heat Treatment
Heat treatment is not a mandatory requirement of ASTM A105 piping components. However, there are some exceptions: ASME B16.5 flanges Class 400, 900, 1500, 2500; Flanges of special design where the design pressure at the design temperature exceeds the pressure-temperature ratings of Class 300; Flanges of special design where the design pressure or temperature are not known; Forged fittings or valve parts which are over 4″ and Class 300.
The typical heat treatment conducted for A105 forgings includes annealing(A), normalizing(A), normalizing and tempering(NT), quenching and tempering(QT). Especially, normalizing at approximate 950°C for 2.5 hours is often required by many clients to eliminate possible internal stress in the forgings. These materials are usually marked as “ASTM A105N”.
Machinability
Machinability of A105 carbon steel forging is good as for any of the low alloy steels.
Applications
This ASTM specification covers carbon steel forgings for piping applications such as flanges and fittings (45°eblow, 90° eblow, tee, coulping, etc)
What is Export Package for Flanges
- Apply antirust oil to flanges.
- Wrapping them with plastic foam.
- Packing them into wooden case or pallet.
- Stick shipping mark on the outside of wooden case.
How to Guarantee the Quality of Flanges
- Visual the surface of buttweld flanges body. Such as dents, die marks, porosity, undercuts.
- Check the marking. Such as size, type, grade, thickness, heat No.
- Measure the dimensions. Such as diameter, thickness.
- Test the chemical properties of flanges.
