Incoloy Material Specification for Flanges

Incoloy Material Specification for Flanges

Incoloy Material Specification for Flanges

Hello All,

Good Day..!

I need to order an Incoloy flange. I have a very old piping class given to me and that says it is ASTM A425 (which is in the form of rod and bars).
There is another grade, ASTM A564 (which is forging).
While comparing I found chemical composition and mechanical properties are same but A564 has not been annealed.

Having said that, my doubt is whether this heat treatment has any impact on selecting A564 in place of A425 having same Chemical composition and mechanical properties?

Vendors have quoted for mix of these, but I feel A564 is better suited for manufacture of flanges.

Thanks in advance

RE: Incoloy Material Specification for Flanges

I think you meant to say ASTM B425 and B564

RE: Incoloy Material Specification for Flanges

Shouldn't that be B564 rather than A564?

denlow60 & XL83NL,

Yes, you guys are right. it is ASTM B425 and B564
Typo from me... or rather we are so used to say A105, A106, A182... etc.. :)

RE: Incoloy Material Specification for Flanges

If you look in ASME BPVC SEC II - B - 2013.
Here you will find in SB -163 all you need to know about B425 / N08825 ,
and SB - 366 you can find everything about B564 / N06625 .

I hope you got something here .
