18 Οκτ 2024 · 440C Stainless Steel. 440C stainless steel is known for its high hardness and excellent wear resistance due to its elevated carbon content (0.95-1.20%). After heat treatment, 440C can reach very high levels of hardness, which makes it suitable for applications that require wear resistance.
Alloy 440C is a high carbon, hardenable, martensitic grade of stainless steel, which offers high wear resistance, combined with a moderate resistance to corrosion. A successful PM (powder metallurgy) version of the alloy should exhibit a high sintered density, at least greater than 7.60 g/cm3, i.e., above 98% of full theoretical density.
Dive into our comprehensive guide on 440 Stainless Steel. Learn about its history, properties, uses, and where you can find this versatile alloy in everyday items.
440C (UNS designation S44004) is a martensitic 400 series stainless steel, [1] and has the highest carbon content of the 400 stainless steel series. It can be heat treated to reach hardness of 58 to 60 HRC. It can be used to make rolling contact stainless bearings, e.g. ball bearings and roller bearings. It is also used to make knife blades.
8 Οκτ 2024 · 440 stainless steel is a high-carbon-chromium 400 series martensitic stainless steel, which comes in four variants: 440A, 440B, 440C, and 440F. It is primarily composed of 0.60-1.20% carbon and 16-18% chromium. 440 conforms to standards like ASTM A276 and AISI 440, with equivalent grades such as SUS440.
7 Φεβ 2023 · The mechanical properties of 440C stainless steel are very impressive due to its unique composition and heat treatment process. This alloy can achieve a tensile strength of up to 980 MPa (144 ksi) and an ultimate yield strength of 885 MPa (129 ksi).
440C is a high-carbon chromium stainless steel designed to provide moderate stainless properties with maximum hardness. 440C can be found in a diverse range of applications owing to the excellent wear resistance coupled with corrosion resistance. This alloy is magnetic and is used in the hardened and tempered condition.
