SA-668 Yield Strength

SA-668 Yield Strength

SA-668 Yield Strength

(OP)
Hi,
I have a forged clevis, Fig 299 from Anvil products. I was wondering if anyone know the yield strength of the material. I looked up the ASME Section II, Part D, with no luck. Answers greatly appreciated.

RE: SA-668 Yield Strength

I wonder if the Anvil Products people might know their own products better than anyone here on E-Tips? Maybe they even have a phone and some knowledgeable engineering people. Give them a try.

I called them couple of times. They only provide with the material specification, which is SA-668. Plus, they are not supposed to know that. It should be in the ASME code. I'm stuck in the calculation.

Thanks Jerehmy.
Yes, the first link is the product. Also, SA-668 is same as ASTM A 668, which you have.

RE: SA-668 Yield Strength

Look at the link showing the clevis, and just for the heck of it, compare the working loads with the area of the tension legs, (2)(W)(T). This should give you some sort of an average working stress, as some basis for your calcs. Also note, the ‘Approvals,’ the fifth item down, maybe those Fed. Specs and Stds. will give you some clues. ASTM A 668 is just a general steel forgings spec., and it includes a whole class of steels and various treatments, to finally get you to a min. yield and ultimate stresses, etc. Someone has to know these values from a part number or some such. The values and the material the clevis is made of is not some darn national security secret. Don’t give up when the first person doesn’t have the answer to your questions, remember they get paid by the hour, not on the basis of working a little harder to get you the right answer. Ask for a contact at their suppliers, someone who does know. Their usual question is what size clevis do I need to carry “X” pounds, so you are stretching their experience.
