I had to have a lab make the tensile strength tests but considering all the tests on the #2 graph look like that graph I can't believe they made a mistake 3 more times.
I'm really at a loss to explain the graph shape. Seems like everyone I talk to can't explain how to get 4130 tubing to look...
Metallographic analysis was done on both samples. Structure description and decarb numbers were almost identical. I've had the samples tested more than once.
Hi everybody!
Looking for some help. I'm trying to compare and ultimately duplicate a 4130 tubing graph after UTS testing of two similar materials.
In graph 1, this is the material I currently have. The graph shows that it is very resilient up to the yield point and very linear (and typical of...
