I am trying to specify a threaded stainless steel rod to anchor into a wet well (see image).

I am seeking a threaded stainless steel rod with a higher available yield & tensile strength than 30 ksi & 75 ksi, respectively.

What would be the most common high strength (like a Grade 55, 105, or greater) threaded stainless steel rod to specify?

Comments/suggestions are appreciated.

Duplex stainless, 2101 or 2205 are suited for this.
You would be looking at about 65ksi yield 95ksi UTS depending on which grade.

What would be the ASTM designation for a Duplex 2205 threaded anchor rod? My goal is to properly specify it on my plans.

There is actually quite a list of alloys, UNS numbers
S31803
S32205
S32101
These three are the most common.
Others:
S32202
S82011
S32001
S82013
S82122
S32003
S81921
S82031
S82121
And a good ref
