If you see ' 440 steel' then assume it's 440A .As there's been lots of 440A blades that gave a bad reputation. 440B is good for choppers as in my stainless kukri. Well HT'd 440C makes a good blade for a hunting knife. In more recent times better steels have been developed such a 154CM. 440C STAINLESS In Stock Castle Metals SiteStainless Steel 440C is a high carbon chromium stainless steel. It has great corrosion resistance when hardened. It shows great resistance to wear and abrasion.
One of the hardest types of stainless steel after heat treating, 440C offers excellent wear and abrasion resistance. It's often used for bearings, valves, and knife blades. Oversized Bearing-Quality 440C Stainless Steel The width and thickness are oversized for finishing to your exact requirements. 440C Stainless Steel Plate - UNS S44004Type 440C (UNS S44004) is a martensitic stainless steel with high carbon and chromium content. After heat treatment, it is capable of attaining the highest strength, hardness and wear resistance of all stainless alloys. 440C stainless steel derives its corrosion resistance from the inclusion of chromium, and is comparable to grade 304. AISI SS 440 Stainless Steel 440C 440A 440B Material Dec 14, 2019 · SS 440A, 440B and 440C stainless steel are AISI and ASTM standard high carbon high chromium martensitic stainless steel, SS440 has high strength, good hardness, corrosion resistance, wear resistance and high temperature dimensional stability. For AISI 440 stainless steel datasheet, heat treatment and equivalent chart, please see the tables below.
- IntroductionKey PropertiesCompositionMechanical PropertiesPhysical PropertiesGrade Specification ComparisonPossible Alternative GradesCorrosion ResistanceHeat ResistanceHeat TreatmentGrade 440C stainless steels are high carbon steels, which attain the highest hardness, wear resistance and strength of all stainless steel grades after heat treatment. These properties make this grade suitable for applications such as valve components and ball bearings. 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 iChina 440-A Stainless Steel Plate Available Inventory We're well-known as one of the leading 440-a stainless steel plate available inventory manufacturers and suppliers in China.

Stainless Steel Alloy 440 - Continental Steel & Tube CompanyJul 09, 2014 · Type 440 Stainless Steel, which comes in four different grades, 440A, 440B, 440C, 440F, offers good corrosion resistance along with abrasion resistance. All grades can be easily machined in their annealed state, they also offer resistance to mild acids, alkalis, foods, fresh water, and air. Type 440 can be hardened to Rockwell 58 harness.
Harder than our other 304 stainless steel, these thin sheets offer better wear resistance for use as a wrap, liner, or cover. Easy-to-Machine Multipurpose 304 Stainless Steel When compared to standard 304 stainless steel, this material can be machined faster with less wear on cutting tools.Stainless Steel Alloy 440 - stainless-sheetsType 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,
