[TheForge] Stainless hardening question

Thu Apr 1 13:05:01 2004

You have to first answer what type (alloy) you used to make your knife.  If
you used a 300 series, most likely 304 or 316 you are out of luck.  If you
used a 400 series, such as 420 then it can be heat treated.  Is it magnetic
at room temperature?  If so it is not a 300 series but a 400 series.
Commercial stainless steel knifes are 400 series.
