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%.
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.

Grades 440A and 440B are identical except for slightly lower carbon contents (0.60 - 0.75% and 0.75 - 0.95% respectively); these have lower attainable hardnesses but slightly higher corrosion resistances. Although all three versions of this grade are standard grades, in practice 440C AISI 440B Stainless Steel vs. Hardened AISI 440C difference between 440a and 440cAISI 440B Stainless Steel vs. Hardened AISI 440C. Both AISI 440B stainless steel and hardened AISI 440C are iron alloys. Their average alloy composition is basically identical.

Slightly less corrosion resistant than 440A, 440C is more widely used and is better regarded because it takes and holds a sharp edge, that is tougher and more stain-resistant than ATS-34.
440 A - 440 B - 440C stainless steel The carbon content (and hardenability) of this stainless steel goes up in order from A (.75%) to B (.9%) to C (1.2%). 440C is an excellent, high-end stainless steel, usually hardened to around 56-58 Rc.
