How to use these reference values

These are the same editorial reference ranges used by the material library, not certified product values. Match product form, temper, thickness, temperature and test direction. Do not enter a tensile-strength range directly as an allowable stress. Use an applicable qualified material condition in the calculator and choose a safety factor for the design criteria.
