[qqquaker]

Can anyones tell me what is the difference between A105 & A216 . I tried to purchase A105 body type ball valve but they only offer A216 GR WCB and said it will be same material. Is this true .
Sincerely,

A-216 is the ASTM Specification for "Steel Castings, Carbon, Suitable for Fusion Welding for high temp seervice."

A-105 is for forged fittings.

These are similar materials. WCB is welded to carbon steel on a regular basis.
