440B. The 440B grade of stainless steel is ideal for crafting blades in areas when they need higher toughness than 440A and higher stain resistance than 440C, such as wet knives for cooking. 440C. With the greatest amount of carbon out of the 440 variants, this is considered to be the strongest and most desirable steel for knife makingespecially over type 440A (except in aquatic conditions). 440A, 440B, 440C, 440F, 440F Se HARDENABLE CHROMIUM 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
Mar 22, 2019 · AKS 440B & 440C will be more wear resistant but not as tough as AEB-L. Ive never messed with 440B. 440C is a very good steel for knives that often gets a bad rap. There was a time when if you talked about stainless in a custom knife it meant 440C, this was before the days of 154cm. 8Cr13mov VS 440C BladeForumsMar 23, 2012 · 8Cr13Mov basically = 440B, so if both are well heat treated, 440C will be a step up in edge holding, I wouldn't think either should have any problems chipping since neither should be especially high on the RC scale, I'm not sure about toughness, I would say 440C would also be better there, but I would say its going to depend more on heat treat and blade geometry how tough each AISI SS 440 Stainless Steel 440C 440A 440B Material Tempering & Hardness. For 440A and 440B stainless steel, 150 °C 370 °C, and can get the HRC hardness 49-57 for 440A, 53-59 for 440B steel. For 440C stainless steel, tempering temperature and corresponding HRC hardness, as follows. Max 160 °C, 60 HRC.
Jul 30, 2019 · 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. 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.

Is 440 Stainless Steel A High-Quality Knife Metal?Specifically, the 440C stainless steel has higher carbon content compared to 440A and 440B stainless steel. Besides being one of the regularly used steels as knife blades , 440 stainless steel has a proportionate amount of hardness and carbon. 440A and 440B stainless steel lack hardness, whereas 440C stainless steel has high strength and corrosion resistance.
To know the differences between steels, its essential to have a look at their properties. When you know what makes up steel, youll get a better idea of why it is the way it is. For 440 steel, things can get confusing. This is because there is more than one way to get 440 steel.

440A and 440B for better homogeneity than 440C but still suffer from primary carbides 17-7PH for more of the same as compared to 17-4PH The growing family of fully densified powder metals gives great opportunities for combining all the properties except affordability. Stainless Steel - 440 Stainless Steel - BEARTECH ALLOYSIf annealed for maximum softness, Types 440A, 440B, and 440C Stainless Steels can be moderately cold formed with only slightly more difficulty than the lower carbon, lower chromium grades of stainless steel. They can also be hot headed.

Possible alternative grades to 440 stainless steels Grade Reasons for choosing 440C 440A/B Slightly softer and more corrosion resistant grade needed
Grade 440A and 440B stainless steels, on the other hand, have similar properties - except for a slightly lower percentage of carbon in grade 440A. All three forms of grade 440 steels are commonly used. However, grade 440C is more readily available than the other standard grades. All About 440 Steel (Properties, Strength, and Uses)
