"For a specific value regarding minimum CVN impact energy, I would use 20 ft-lbs (27 J) at the minimum temperature of interest."
How did you arrive at 27J? Is there a reference or standard that reccomends CVT impact energy values for different applications? I've found values ranging from 18J to...
Thanks metengr.
Q235 is similar to A36 with regards to processing and properties. The chemistry is where things vary a little. Grades A and B allow higher P and S content than grade C.
I've been reading more since you replied and have a few more questions:
1) Which value should I be using for...
Here is some background on the material before I get to the question:
From GB/T700-06 Q235
Gr A 21J @ +20C, Carbon .22%
Gr B 21J @ 0C, Carbon .20%
Gr C 21J @ -20C, Carbon .17%
The graph in the link below shows that there can be a fairly wide temperature range between maximum impact energy and...
What is the magnitude of the effect on weld strength of welding a nitrided part? The formation of iron nitrides will have some effect but I have not been able to find values suitable for design calculations.
A little background into my application:
A nitrided 1010 pin is welded all around to...
How does the corrosion resistance of a nitrided 1010 steel part compare to e-coating, dacromet, zinc plating, etc... the same part?
Is there a standard or article out there that compares surface treatments that would include nitriding?
