They are probably made from 300m

Chemistry data for 300m:
Carbon= 0.38 - 0.46
Chromium= 0.7 - 0.95
Iron= Balance
Manganese= 0.6 - 0.9
Molybdenum= 0.3 - 0.65
Nickel= 1.65 - 2
Phosphorus= 0.01 max
Silicon= 1.45 - 1.8
Sulphur= 0.01 max
Vanadium= 0.05 min

I doubt very much it's 300m. My guess is 4140. A simple rockwell test will tell you quick enough.
