6 Questions
How is the yield point determined for steel with a well-defined yield point?
By the drop or halt of the gage of the tensile testing machine
What method is used to determine the yield strength for steel without a well-defined yield point?
0.2% offset method
What additional requirement is imposed when using the offset method to determine yield strength?
Reporting the stress at a tensile strain of 0.0035
What is the minimum stress required at a tensile strain of 0.0035 for Grade 75 steel?
75,000 psi [520 MPa]
What is required in addition to determining yield strength using the offset method?
Performing a second tensile test
How is the yield point determined when steel tested does not have a well-defined yield point?
Applying the 0.2% offset method
