420HC Stainless Steel vs. 440C Stainless Steel for Knife difference between 440a and 440c

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 440A vs 440C BladeForumsOct 14, 2011 · 440C has much mroe carbon that 440A, so it can take a sharper edge, hold said edge longer, but have lower rust resistance. In progression from 440A-B-C, the edge properties go up, but rust resistance (and I believe toughness too) go down. Same with AUS-4-10. If I am not mistaken, 440A has around .6% carbon while 440C has around 1.0-1.1%.

440A vs 440C vs other choices for knife - Finishing

Jun 12, 2009 · A. John, I'd consider the corrosion resistance of 440A and 440C to be so close as to be equal. The difference between these two grades is in hardness and ductility, due to the higher carbon content of the 440C.440A vs 440C? The High RoadJul 09, 2007 · 440C has a much higher carbon content. Just off the top of my head, I believe A has a carbon content of 0.60% to 0.80%, while C is 1.00% to 1.20%. There's a slight difference in chromium as well, I think. Overall, 440C will generally be harder than 440A, but both steels are good for knife blades.440A vs 440C? The High RoadJul 09, 2007 · 440C has a much higher carbon content.
