Great feedback form everyone - thank you.
Moving forward, to avoid these issues, what grade of round bar steel would best perform to hit the 27Joules minimum with just a normalize - is any?
Again the customer clearly specified either:
CAN/CSA G40.21 Grade 300W
or
AISI 1045 in the Normalized...
Double normalizing would be ideal, as it is about 1/4 the cost of a Q&T. I am working with the Q&T and Normalizing facilities now to find out what they can guarantee as far as results are concerned. I am under the gun, obviously under knowledged, and in trouble with costs. Happy New Year to me.
Results for CORYPAD attached.
METENGR - testing was -20 C, I assume that will make a difference?http://files.engineering.com/getfile.aspx?folder=0378235b-f7ac-4f15-8f48-db18216da51b&file=1045_Normalized_Bar_Results.PDF
Sorry for leaving out that critical piece of information. Testing is done at -20 degrees.
They gave us an option to use "either/or" in the case of the grade 300W or 1045. The 1045 was more readily available and after talking with our lab personnel, we believed the 27 Joules would not have...
Hello everyone and thank you for reviewing my post/question and offering your expert opinions.
Here is the trouble: I have a project I am working on that calls out for the following: CAN/CSA G40.21 Grade 300W OR AISI 1045 in the Normalized Condition. Needs to conform to min yield of 350MPa...
