Keith apparently declined to read the stress-strain report. Middle on right - Yield @ .2%. "Short version of tensile testing" was the topic.
No Preacher, I was commenting on your understanding of the definitions (or lack thereof). I was not commenting on what a trained metallurgist who actually undersands this stuff reported.
The metallurgist didn't provide this incorrect definition to Lloyd... you did:
Yield strength or elastic limit is the stress which gives a permanent deformation of 0.2%.
Copy-and-paste of information, along with impressive pictures and graphs, is not going to hide the fact that you don't really understand this stuff called steel... even many of the basics.
Here's a thought... Why don't you pay a good Metallurgical Engineer at METL to write your posts on this subject for you. Then you can pretend to be an expert, and fool a lot more people.
