SAE J249 Grade 8 compliance

SAE J249 Grade 8 compliance

SAE J249 Grade 8 compliance

(OP)
I am in the situation where our supplier is short on SAE J429 grade 5. Looking to see if SAE J249 grade 8 will comply with ASME B31.3 process piping. Flange connections are 4, 6 & 8".

Any help, reference or link will be appreciated,

Thanks
 

RE: SAE J249 Grade 8 compliance

You should be specifying ASTM A193 B8 stainless steel fasteners for B31 piping.  Preferably B8 class 2.

Is it stated in ASME B31.3 anywhere. I just need to confirm.

Thanks

Have you looked in B31.3?  If you don't have a copy, how can you confirm what I -- or anyone else -- tells you?

I did some searches in B31.3 for SAE J429, then just J429, ... Nope, that material is not found.

I can't necessarily confirm tothepoint's recommendation (B31.3 says ASTM 193 is for High Temperature or High Pressure Service and Other Special Purpose Applications) and I don't know enough about your application to make a recommendation.

But circling back to my first point -- you're the engineer.  If the part fails, what are you going to tell your management, your customer, the judge (if there's a lawsuit) -- somebody on the Internet told me it was ok?
