Properties for ASTM A193 B7H??
(OP)
Hi folks,
Anyone know if this material is covered in the standard? I have been searching my reference books and internet and find reference to ASTM A193 B7 & B7M, but not B7H? If this is covered, I would be willing to purchase the standard. Just would like to know if it's in there before spending the money.
Thanks for your help. :)
PS. would appreciate any notes/comments on why it might be recommended over B7.

My application:
The B7H designation is stamped on the end of some studs that we were going to install on a reactor that has H2S in the process. Instead, we are going with B7M studs. We have had these studs here for a while. Will have to back-track and find out where we got them and maybe supplier can provide some information/specs.
Someone elses application:
Smith Valve's "Alloy Steel API trim 8" gate valve. The gland studs (item 11) are B7H supposedly. See Link.... http
With your comments that B7H doesn't exist (and I agree with you) I am pretty confident that B7M is the correct material to use so finding out what B7H is, is just a curiosity thing. I appreciate the help guys. Thanks for the info.

I would reject these studs and replace with B7M noting that B7M does have lower allowables than typical B7 so you would want to verify the flange design with these.

Still a good catch though. B7M is the correct material to use.
Sorry for the head scratching questions guys. He, he.
