ASTM A105 Steel Applications


Typical applications for this grade of steel include pipes, valves and flanges.
 

Shapes and Sizes 


E Steel Sdn Bhd supplies A105 steel Round bar in a variety of sizes ranging from 3/4”- 12”.

Heat Treatment


Heat treatment is not required except for ASTM A 105 carbon steel forging. However, there are some exceptions that will require heat treatment to improve its mechanical properties for better application.

The typical heat treatment conducted for A105 carbon steel 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”.



Characteristics

  • A105 and A350-LF2 are standard specifications for forged carbon steel piping components. A105 for ambient and higher-temperature service; A350-LF2 for low-temperature service with Charpy V-Notch impact energy testing. Components include flanges, various fittings and valves.
