[TheForge] source for 440A flats - knife stock

[mrscherm at aol.com]

Not a silly question at all. 440C is what most people use now for 
knives because it is much easier to find, and because they dont 
purchase enough to buy a heat of steel. 440A is more easily forged 
(more forgiving of temperature variation) because it has a slightly 
lower carbon content. Back when the US actually manufactured goods here 
in the states, you could purchase at least 5 different analysis of 440 
(A,B,C, F, FMSe or FM) depending on how you were making the part; 
forged, machined, cold headed, etc. No longer the case unfortunately. 
The reason 440C is available today is because of the bearing industry. 
If they start making bearings from something else, "C" will disappear 
also.

Just a silly question. Why do you want 440 A and not
440 C that most people use?
