Hi,
I've been asked to make some replacement power valves for a 2-stroke motorcycle. I had the material analysed, and it's 2024. I forgot to ask for a hardness test to see if the temper could be determined.
I don't know what the max temperature is that the part will see (it's on the edge of...
Thanks metengr,
Is 4320 used in similar applications now?
I'm going to the heat treaters monday morning to get some input using the 4320 in respect to the heat treating process
Hi forum,
I have been given a wheel that has hooked teeth on the periphery that is used to cut up recycled plastic. I have to replicate the part, including if possible the material.
Using emmision spectroscopy the testing lab thinks it appears to be similar to 1552 steel. the constituents are...
Tmoose,
If you were doing Dye pen inspection on a used crankshaft (I assume it was used) maybe the crack(s) were full of oil, which might prevent proper absortion of the dye.
Just wondering
The initial question is from a project I did a few months ago, we had a support bar that we had to widen due to a stress concentration caused by a hole in the support bar. It wasn't until after we had made the part that we realised that we had a problem with the fracture analysis.
I had a...
RON,
We have recommended that our customer use dye penetrant inspection, and the use of a microscope to verify the absence of cracks.
Apparently their technicians are well versed in the use of dye pen. We’ve recommended a vigourous system, where the customer will check the part every xxx...
I did call the local NDI house, their mag particle operator said that ANY crack detectable was cause for rejection, they never had cause to measure the crack length, that wasn't required either by his customers or by MIL-STD 1944.
He did think that they could find crackes less than .030" long...
We have made a part that requires us to analyze the part using AFGROW fracure prediction software.
The customer specifies that we need to conduct the analysis using an initial flaw size of .03" long by .015" deep. With the part we have made we are getting marginal cycles to failure.
Can mag...
Using the classical model of a single edge corner crack (not the one with the user defined beta solution), a crack with the dimensions of A = C = 0.015625” is applied to a specimen with the dimensions of 4” width and 0.120” thickness.
A max stress of 41 ksi and stress ration of R = -1 is...
Hi
I'm looking for 316H bar 6in dia for a project I have. It needs to have a min carbon content of .39%
Does anybody know of any sources?
I appreciate any help anybody can give me.
NTN has developed an FW series bearing which is 1mm thick, but it doesn't appear to be commercially availible.
