In the spirit of metal information, found this on blade forums:

S7 Impact toughness at Rc of 57 = 125 (ft-lbs)
CPM3V Toughness at Rc of 58 = 85 (ft-lbs)
CPM3v Imp.Toughness Rc of 60 = 50 (ft-lbs)
A2 Impact Toughness at Rc 60 = 40 (ft-lbs)
D2 Impact Toughness at Rc 60 = 21 (ft-lbs)


S7 really stands out!

If SR-77 is anything like AngelSword's S7 with ThermaCycle (and Dan's comments make me think it is), its toughness in the same impact test is 250 ft-lbs.

Whether SR77 is closer to 125 foot pounds or 250 foot pounds of toughness, it's a world away from the fantasy-land bs about stainless steels being tough.

SR-77 - McClaren F1
Stainless steel - civic with wing, decals and oversized muffler.


Hmmm... Actually, the SR-77 should be a hooked up 5 liter fox mustang... Priced cheap but is a crazy performer! <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" />
