[Kevin Evans]

could one of you guys tell me what steel this is?
Carbon .95-1.05
manganese .40-.60
chromium 5.00-5.50
Molybdenum 1.00-1.20
vanadium ..20-.30

Thanks in advance also please tell me where to find imformation

I don't really know. I have a sheet on 52100, which is pretty high in Chromium, as far as forging steels go, and only has 1.3 - 1.6 Chromium, and the one you list has 5%!!
I wonder if what you have is some type of stainless?

[kbaknife]

Nope - I guess it's not stainless. Stainless - to be called "stainless" - requires more chromium than that. Like maybe 10%.

I think its A2 tool steel. Google Carpenter no.484,I think thats what you have.

[kbaknife]

I think you're pretty close on that A2 choice:

   1.0% C, 1.0% Mn, 5.0% Cr, 0.3% Ni, 1.0% Mo, 0.15–0.50% V

Thanks Guys
So  does that mean its good knife material ?

I don't have a clue.I got it cheap ,but won't use it for blades if its junk.
Its a pretty big sheet thats 3/32 thick

for stock removal A2 is good stuff.

Lot of guys use it.

A-2 Tool Steel
     Heat treat temperature    1700-1900 F
     Quench    Air
     Hardness    Rockwell 59c-62c
     Applications    A2 can be used in the same applications as both O1 and W1, but the heat-treated air-hardening steels have deeper hardenability and there is less movement or distortion during heat treatment.
