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.
Mechanical Properties Type 440C 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. Compared to austenitic grades, 440C has moderate corrosion resistance, comparable to 304.

AISI 440C stainless steel is a martensitic stainless steel formulated for primary forming into wrought products. 440C is the AISI designation for this material. S44004 is the UNS number. It can have the highest tensile strength among wrought martensitic stainless steels.
440C Stainless steel is a type of modern steel and famous for its high corrosion resistant, wear resistance, strength and hardness qualities, among all the stainless alloys, capable of attaining (after heat treatment) the highest hardness (60 HRC). It has good resistance to the
Apr 19, 2017 · Basic Properties of 440 Stainless Steel Corrosion resistance All types of grade 440 stainless steel have a high corrosion resistance. Therefore, grade 440 is ideal for use in tempered, passivated, and hardened conditions.
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 expensive for this process. Some manufactures are intentionally vague about the type of steel
440C is a hardenable chromium steel. It has one of the highest attainable hardnesses of the corrosion and heat resisting grades. It has one of the highest attainable
Abstract 440C steel is a high carbon martensitic stainless steel with excellent mechanical properties. This paper describes the effect of heat treatments on microstructures and mechanical
AISI 440C is a high carbon chromium steel designed to provide stainless properties with maximum hardness. It has been used primarily as a bearing steel, and is used in the hardened plus tempered condition. When heat treated, Type 440C attains the highest hardness of
440C should be welded with Type 440C filler weld metal if the mechanical properties of the weld metal must be similar to those of the parent metal. In welding annealed material, the steel should be preheated to 600°F and annealed following welding by heating uniformly and
Welding Use type 440C or 420 filler material. Annealed MaterialPreheat to 600/800F. Maintain above 600F during welding. Reanneal or temper 1300F 4 hours. Hardened MaterialPreheat to 25F below original tempering temperature (400F minimum). Maintain above
440C steel is a high carbon martensitic stainless steel with excellent mechanical properties. This paper describes the effect of heat treatments on microstructures and mechanical properties of 440C steel. Solution treatment was carried out at 1150oC
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.
