A105 vs. A216 WCB valve material

A105 vs. A216 WCB valve material

A105 vs. A216 WCB valve material

why would a customer not accept A105 valve material in lieu of A216 WCB. I thought they were pretty close to equal as far as material properties and characteristics.

RE: A105 vs. A216 WCB valve material

That's a question for the customer to answer.  I have seen them used interchangably

RE: A105 vs. A216 WCB valve material

Some applications are well suited for forgings and not well suited for castings.

RE: A105 vs. A216 WCB valve material

For larger sizes a forging may be more expensive than a casting. A forging is a superior qualifying material. Will not entail additional heat treatments and examinations as required by castings.

What are those applications where a forging may not be used?

RE: A105 vs. A216 WCB valve material

SVI answered this one pretty well.  The only thing i would add is that, in my experience, A105 is generally used for small bore valves.  A216 is for larger bore valves (> 2").  Service fluid, conditions and customer preferences should all be taken into account, here.
