18 paź 2024 · 440 stainless steel is a high-carbon martensitic steel. Its high carbon content makes it heat-treatable to high levels of hardness and wear resistance, making it one of the most robust stainless steel variants for tools requiring a durable edge.
AISI SS 440 (440A, 440B, 440C stainless steel) is high carbon martensitic, SS440 material composition, properties, HRC hardness equivalent to European EN.
8 paź 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.
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.
