These carbon steel ASTM A105 Flanges have improved mechanical properties because forging refines and directs the flow of grain according to the shape of the piece, which in this case is the flange. Forging reduces the weight required to manufacture the ASTM A105n Weld Neck Flanges, therefore, thereby providing significant cost savings. Also, since the flanges have less excess, the CS SORF Flanges A105 would require less machining hours along with much less material which could be used to clean the piece at the end.
ASTM A105 Flanges
SA105 Pipe Flanges
CS SORF Flanges A105
Forged carbon steel components such as flanges produced in accordance with ASTM A105 are designed for use at both ambient as well as elevated temperature settings.
In order to improve its performance at elevated temperatures, the Carbon Steel ASTM A105 Blind Flanges are often heat treated by the performance of procedures such as annealing, normalizing, tempering, or quenching. After undergoing forging operations, the ASTM A105 Carbon Steel Flanges is to be subjected to tension test, hardness test and hydrostatic test, with the latter being applicable when required. Recommendations for retreatment, repair by welding, and product marking for the Carbon Steel SA105 Pipe Flanges are given in the specification.
