Intrepting Result from a Charpy Test

Intrepting Result from a Charpy Test

(OP)
Good Afternoon all,

I have a query about results from 2 no. Charpy Tests.  The results were 31 & 30 joules (average) and I wonder if there were reference tables helping me to get a feel for the type of steel I was dealing with.  

Any help would be appreciated.

TestingTom;
Why don't you send one of the Charpy impact test samples (broken piece) to a metallurgy/materials test lab that can perform a chemical analysis or if the Charpy impact test was performed by a metallurgical lab have them do this for you? The cost should be under $100.00 USD and will give you the specific information you need.

metengr has a very good idea.  Charpy value alone isn't going to tell you a thing.  (Okay, it might rule out cast iron.)

RE: Intrepting Result from a Charpy Test

Thats correct. You can't tell what kind of steel only from impact test.
If you have the pieces perform an PMI-Test or a chemical analysis by spectroscopy its quite cheap and you can exactly say what kind of grade you have!
