: What makes a given stainless steel a "spring" stainless steel? I've seen this term used in a few places but I am not sure what this means specifically. I'm guessing it has to do with chemical composition, heat treat, or temper. Am I close?

Stainless steel for springs take advantage of the high work hardening rate of austenitic stainless steel. The steel is cold worked to "tempers", that is increasing degrees of cold work. This increases the yield and tensile strength to various levels. full hard is normal for springs and this implies a yield strength of over 150,000psi...I forget exactly.
