[TheForge] SS alloy advice?

[Grant Marcoux]

Hi James!  Howz life in WA?  Have you taught any classes lately?  Are you
planning to?  Things are fine in the bay area...most of the smiths I know
are busy.

 I'm not too familiar with the austenitic stainless alloys.  There must be
another constituent that makes long-term elasticity possible.  Perhaps these
are of the duplex alloy family where nickel influences them.  I don't have
the specs.  Grant

Hey Grant,

How are things down in the Bay Area?

The 300 series is the standard alloy family for stainless springs
301,302 and 17-4PH(317) are the most common 316 is used where extra
corrosion resistance is needed.
