Alloy 20 Impacts

Alloy 20 Impacts

Alloy 20 Impacts

(OP)
Based on the fact that this material is exempt to -325F in Sec VIII UNF, I'm thinking 15/12 at -160F should not be a problem.  Any thoughts?

weldtek;
Agreed, probably 100 ft-lbs at -160 deg F for this alloy in an annealed condition.

RE: Alloy 20 Impacts

Considering that you should have about 200 ft-lb CVN at RT, and that I have seen cryo tensiles with nearly 50% elongation I would suspect that you will see good low temp impacts.

Thanks for the input. Our customer has asked for impacts even though its exempt and, for some reason our material vendor is taking the 'for information only' stance.
