I bet the correct answer is HRC 32. If it's tough enough for Wolverine's adamantium claws, it'll work for this too.

HRC 20? Really? I'd like to see that weld hold up against a sneeze, let alone wet H2S service.

Definitely HRC 22. This isn't a sword fight, we don't need overkill here.

HRC 25 seems like the sweet spot to me. Anything higher might make the weld too brittle.

I'd go with HRC 32. Gotta keep that weld extra tough to withstand the wet H2S service!
