But in practice it tends to be used on cheap knives and gets low end heat treatment and thus the performance is often very low. 440C High-end Stainless Knife Steel - Buy OnlineBuy 440C High-end Stainless Knife Steel Online - 440C High-end Stainless Knife Steel 440C Stainless Knife Steel is the high-end of the 440 stainless steels. Being harder than the others, keeping a sharper edge much longer than standard 440A or 440B stainless steels.
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- A Love Hate Affair by Jay Fisher440A:this is a hardenable stainless steel alloy, hardenable to a higher hardness than 420 series stainless steels (which are only hardenable to 52 HRC). 440A has good corrosion resistance, and is used in less expensive bearings and in harder surgical tools (rare). It has 0.6 to 0.75 percent carbon, about the same carbon content as most steel 7Cr17 7Cr17MoV 440A stainless steel - News - Ahonest High carbon chrome martensitic stainless steel 7Cr17 7Cr17MoV equals to ASTM 440A, SUS440A. Based on 7Cr17, little molybdenum and vanadium has been added into 7Cr17MoV in order to improve hardness and wearing resistance of the steel.
Both AISI 440C stainless steel and EN 1.4116 stainless steel are iron alloys. They have a very high 97% of their average alloy composition in common. There are 31 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown. Compare 20 Grades of Knife Steel - ThoughtCoJul 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. Compare 20 Grades of Knife Steel - ThoughtCoJul 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.

Actually 440A Stainless Steel is at caliber with AUS-8,Sandvik 12C27,425 Modified,and N680 in edge retentionmiddle class stainless steels.It was a commonly used stainless up until the mid 1990s by Imperial Knives USA,Schrade USA,and Camillus for the knife models they offered in stainless steel.The steel was discontinued in use because of How to Heat Treat 440 Stainless eHowThe 440 series of stainless steels are a good choice for knife-making because they have reasonable resistance to stains and corrosion while retaining the hardness and toughness of carbon steels. 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.

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 440 (UNS S44000)Nov 07, 2001 · 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 Alloy 440 - Continental Steel & Tube CompanyType 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. 
Jun 12, 2009 · I have heard some disparaging remarks concerning 440A stainless steel, as compared to 440C,with regard to knifemaking. The SOG Navy Seal knife was tested against most major manufactures of this type of all-around "combat" and/or "survival" knife and chosen above all others. This knife is, of course, made from 440A.
