What is 440C Stainless Steel?. ASTM A276 standard grade 440c stainless steel is a high carbon martensitic stainless steel, which is generally supplied in the annealed condition with a maximum Brinell hardness of 269 (Rc29) or annealed and cold drawn with a maximum Brinell hardness of 285 (Rc31).. AISI 440C steel is characterized by good corrosion resistance in mild domestic and industrial

ASTM 440A , 440A stainless steel ,ASTM 440A steel ASTM Grade 440A is capable of attaining, after heat treatment, the highest strength, hardness and wear resistance of all the stainless alloys. Its very high carbon content is responsible for these characteristics, which make 440a particularly suited to such applications as ball bearings and

Tempering in the range 425 565°C is to be avoided because of reduced impact resistance and corrosion resistance. Tempering in the range 590 675°C results in lower hardness (the product become machinable) and high impact resistance. Welding. If welding is necessary pre heat at 250°C and follow welding with a full anneal.

Elevated Temperature Properties 440C is not generally recommended for elevated temperature applications due to a reduction in corrosion resistance when tempered

440Athis 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

Physical Properties Table 3.

440, 440A, 440B, and 440C . Toughness testing usually includes impact in testing apparatus, either in the Charpy test or Izod test. Both tests only measure the relative toughness of materials in a very specific application that is not a knife blade! This is important to understand, because knife blades are very specific use items, and are

May 13, 2008 · 17 4 stainless steel is an age hardening martensitic alloy combining high strength with the corrosion resistance of stainless steel. Hardening is achieved by a short time, simple low temperature treatment. A detailed set of properties, chemical composition range and applications are provided.

440 Series ( 440A, 440B, 440C ) stainless steel sheets ( plates ) for knives manufacturing. Introduction. Grade 440C stainless steels are high carbon steels, which attain the highest hardness, wear resistance and strength of all stainless steel grades after heat treatment.
