301 Full Hard Stainless Steel Question
301 Full Hard Stainless Steel Question
(OP)
I've been getting some 301 Full Hard in from my supplier. The data sheet calls out a minimum Rockwell Hardness of C41, however my in-house testing shows a Knoop Hardness of 550, this translates in to a Rockwell of ~51. Quite a bit more than the minimum spec (Tensile strength of ~1790Mpa vs 1276Mpa), I'm wondering if anyone has experience with 301 full hard... would you say it is normal to see hardness that far above the minimum or can I expect to one day get some material in that will have a much lower hardness?
Thanks.
Thanks.

A666 has no hardness listed at all. Tensile strength, yield, elongation, and bend testing are what are used to specify the degree of cold work.
If your stuff meets the elongation and bend test requirements then it is within spec.
