Grade 440c is capable of attaining after heat treatment the highest strength hardness and wear resistance of all the stainless alloys.
440c stainless steel knife properties.
Like the 420hc stainless steel the 440c stainless steel has the ability to developing a greater hardness than other grades in the 400 series when heat treated.
Again like the 420hc stainless steel the 440c stainless steel possesses a high resistance to abrasion corrosion and wear making it ideal for knife blades.
It has high strength moderate corrosion resistance and good hardness and wear resistance.

After heat treatment it is capable of attaining the highest strength hardness and wear resistance of all stainless alloys.
Grade 440c stainless steel is a high carbon martensitic stainless steel.
According to the chemical composition and the hrc of the aus 8 stainless steel it offers the following properties.
18 is quite high compared to other steel and this is why it may be the best stainless steel for corrosion resistance.
Stronger than the 440a group of stainless steels as a result of higher carbon content 440c is a high chromium stainless that has excellent hardness properties.
With a 59 hrc and high carbon steel the aus 8 steel provides significant edge retention for your knife which is close to premium steel.
Being low end stainless steel the 420hc is a great steel for the low entry knife it has decent edge retention good corrosion resistance and it s easy to sharpen so the answer is yes its good for knives.
14 of chromium offers the aus 8 a high corrosion resistance but still it s not the best.
Compared to austenitic grades 440c has moderate corrosion resistance comparable to 304.
The 0 75 carbon grants the 440a stainless steel a good wear.
With a maximum hrc of 58 it s a hard knife with decent edge retention.
440a has excellent corrosion resistance due to the high presence of chromium in it.

And in comparison with other low end stainless steel the 420hc comes in a good place so owning a 420hc knife would be a smart decision for the money.
