440B vs 440C | BladeForums.com AKS’ 440B & 440C will be more wear resistant but not as tough as AEB-L. I’ve 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.

440C is the superior steel, and it does indeed have more carbon the 440A. Generally the progression runs from 420 series to the 440 series (440A, 440B and 440C). If it just says "440 Stainless" it's probably only 440A (or a lower grade, many offshore 420 equivalents are marketed as "440 Stainless"). Related searches 440b vs 440c stainless steel

List of blade materials - Wikipedia 440 series has three types: 440A, 440B, and 440C. 440A is a relatively low-cost, highly corrosion-resistant stainless steel. In China, Ahonest ChangJiang Stainless Steel developed 7Cr17MoV, a modified 440A, by adding more vanadium. 440B is almost identical to 440A, but has a higher carbon content range compared to 440A.
440C is a mid-range Stainless Steel from the 440 Series (440 A, 440B and 440C) high in carbon (Has more than 1%, which makes the highest carbon steel of the 440 series), it offers excellent wear resistance and corrosion resistance, used for budget and mid-range knives. How to Heat Treat 440 Stainless | eHow 440 stainless is a common, modern knife steel. The 440A, 440B and 440C steels are too difficult to form in their hardened state, so you will need to anneal the blank before you can form the blade. Fortunately, you do not have to quench 440 stainless when you heat treat it; it reaches full hardness of 55 to 57 on the Rockwell C scale with simple 440b vs 440c stainless steel High Speed Steel | 440C Tool Steel | 440C Steel 440C is a hardenable chromium steel. It has one of the highest attainable hardnesses of the corrosion and heat resisting grades. This grade is magnetic at all times. For those applications where superior machinability is desired and where slightly lower corrosion resistance is satisfactory 440C can be supplied.
The 4xx class of stainless steels are alloyed with chromium and are ferritic or martensitic in structure. 440 steel actually refers to four types of steel: 440A, 440B, 440C and 440F steel, which only differ based on the level of carbon in their composition. comparison AUS8-A versus 440C | BladeForums 440b vs 440c stainless steel From my very limited experience with both steels 440c has a higher corrosion resistance and will take about the same edge as AUS-8. AUS-8 has a higher abrasion resistance and is a bit tougher. I have also found the only knife I've done from AUS-8 to hold a better edge than 440c but thats probably because I do mostly kitchen knives from 440c, so 440b vs 440c stainless steel Stainless Steel Alloy 440 - Continental Steel & Tube Company Type 440 Stainless Steel, as known as razor blade steel, is a hardenable high-carbon chromium steel. When put under heat treatment it attains the highest hardness levels of any grade of stainless steel. Type 440 Stainless Steel, which comes in four different grades, 440A, 440B, 440C, 440F, offers good corrosion resistance along with abrasion resistance. 
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. Stainless Steel - 440 Stainless Steel - BEARTECH ALLOYS 440 Stainless Steel: Type 440A, 440B, and 440C . Hardenable high-carbon chromium steels designed to provide stainless properties with maximum hardness ; Have maximum hardness together with high strength and corrosion resistance in the hardened and stress relieved condition Stainless Steel Grade 440B (UNS S44003) Grade 440B stainless steel is annealed at 843-871C (1550-1600F) and then cooled very slowly in a furnace. Cold Working. Grade 440B stainless steel can be slightly cold worked by common cold working methods. Welding. Welding is not generally recommended for grade 440B stainless steel as it tends to harden in air.
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. AISI 440B Stainless Steel vs. Hardened AISI 440C 440b vs 440c stainless steel Both AISI 440B stainless steel and hardened AISI 440C are iron alloys. Their average alloy composition is basically identical. For each property being compared, the top bar is AISI 440B stainless steel and the bottom bar is hardened AISI 440C. AISI 440B (S44003) Stainless Steel :: MakeItFrom 440b vs 440c stainless steel AISI 440B stainless steel is a martensitic stainless steel formulated for primary forming into wrought products. 440B is the AISI designation for this material. S44003 is the UNS number. It has a moderately low thermal conductivity among the wrought martensitic stainless steels in the database.
440C holds sort of a unique distinction in my mind. It was the steel with which I first noticed the sizeable drawbacks of sharpening with natural stones (Arkansas). When I first tried it (on an older Buck '2-dot' 112 in 440C), it seemed the natural stones barely scratched the stuff. 440C- A Love Hate Affair by Jay Fisher 440C: this is also a hardenable stainless steel alloy, hardenable to a higher hardness than 440B. It has good corrosion resistance, and is used in ball bearing balls and races, high pressure nozzles, valve seats and high wear components. 440C vs D2 | BladeForums 440b vs 440c stainless steel 440C vs D2 Discussion in ' 440b vs 440c stainless steel D2 not to bad for vintage tool steel and unlike 440c you can get it to take a forced patina.

Grade 440C stainless steel is a high carbon martensitic stainless steel. It has high strength, moderate corrosion resistance, and good hardness and wear resistance. Grade 440C is capable of attaining, after heat treatment, the highest strength, hardness and wear resistance of all the stainless alloys. 440C Stainless Steel - Carter Crafts There is 440A, 440B, and 440C. 440A and 440B are "softer" grades of 440 stainless steel. While they are VERY rust resistant and will take a great looking mirror polished finish, they will not hold an edge nearly as well as 400C. Factories use the milder steels because the blades are stamped out of sheet of steel using dies. 440C is too hard and 440b vs 440c stainless steel 440C Stainless Steel - BladeOps Advantages of 440C stainless steel for knife blades The Machinery's Handbook states this about 440C stainless steel: "This steel has the greatest quenched hardness and wear resistance upon heat treatment of any corrosion-resistant or heat-resistant steel." 440C is a highly corrosion-resistant tool steel. It has a long and proven history of 440b vs 440c stainless steel

As far as I know all common stainless steel has iron in it, 304/316 does. Its the nickel that does the major part of the rust protection, and the molybdenum in 316 for the harsher applications where 304 can't quite hold up. 420 Vs. 440 Stainless Steel | eHow 420 grade stainless steel has a composition of 12 to 14 percent chromium, 0.15 percent carbon, 1 percent manganese, 1 percent silicon, and tiny amounts of phosphorus and sulfur. 440 grade stainless steel has higher amounts of chromium -- 16 to 18 percent -- and carbon at 0.6 to 0.75 percent. 316l Vs. 440 Vs 904l Steel - The Rolex Area - RWG 440 (mostly 440c) is used in lots of low to medium end knives. generally even the very good stainless steels like hitachi ats-34 and 154cm and d2 (a 'near' stainless) and bg-42 have been superseded by the cpm (crucible particle materials) 'super steels'; s30v, s60v and s90v in higher quality knives.
