4130/4140 mechanical proporties
(OP)
i am trying to do a failure analysis for the impeller made of AISI4130/4140(forging), but i don't know the proporties in the standard specification ,anyone can help me? thanks.

You should be able to find some standard properties on matweb (http://www.matweb.com). Google searches will also turn up quite a bit of information.
Good luck

Are you sure the impeller is a forging and not a casting? Most pump impellers are typically cast products.
What type of failure did you have, and what is the pump?

Tensile - 100,000 PSI (690 N/mm2),Yield - 80,000 PSI (552 Nmm2),Elongation in 2"L - 18%, Reduction of Area - 35%",if i can consider these date are the Minimum Tensile Properties?
