Dear Sir
Selection of material is only engineering scohipe NOT others. Selection of material is based on many parameters as service condition, MDMT, pressure required. if your engineering document has a specified material while you have equivalent one in your local market, then you should to raise concession request (CR) to your client for approval.

Hello,
Is there anyone know the material differences from ASTM A105 and A216 Gr.WCB?
because, if i've seen it based on the chemical and mechanical properties, they're all the same..
Anyone can tell, when we should use A105 or A216?
Nb : It is to be used for Plug Valve Material in pipeline engineering
Any help would be apreciated,
Thankyou
Best regard,
Zihni
