Stainless Steel

Stainless Strip Steel (Cold Rolled) - Temper Classifications -
Note - The various stainless strip tempers are based on specified minimum values for tensile strength or yield strength or both. Here at Precision Steel there is on file a complete record of all such detail including chemical analysis on each item in stock. However, because of custom, both distributors and customers alike rely on approximate Rockwell readings for temper classification. To illustrate:

Temper	Rockwell	Tensile PSI
Soft	Approx. B 87 max	75.000 min.
Quarter hard	Approx. C 25/30	125.000 min.
Half Hard	Approx. C 30/35	150.000 min.
Three Quarter hard	Approx. C 35/40	175.000 Min.
Full Hard	Approx. C 40/45	185.000 Min.
Extra Hard (Tyoe 301)	Approx. C 45 min.	200.000 Min.
Type 430 Soft	Approx. B 75/85	75/85.000
