Best Use Cases. While 440 stainless steel can be used in a wide range of applications, it’s particularly well-suited for knife blades. Its high hardness and wear resistance make it ideal for maintaining a sharp edge, while its reasonable corrosion resistance makes it suitable for everyday use.
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.
440C is a mid-range Stainless Steel from the 440 Series (440 A, 440B and 440C) high in carbon (Has more than 1%, which makes the highest carbon steel of the 440 series), it offers excellent wear resistance and corrosion resistance, used for budget and mid-range knives.
18 Οκτ 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. 440 stainless steel generally contains between 16 and 18% chromium.
7 Φεβ 2023 · Due to its superior combination of physical and mechanical properties, 440c stainless steel is used in a variety of applications, including cutlery (knives), surgical instruments, aerospace components (shafts & valves), bearings & roller components, pump components & valves, ball screws & lead screws, petrochemical industry parts (valves), etc.
In terms of applications, 304 stainless steel is widely used in food production equipment, chemical equipment, medical equipment and other fields with high hygiene requirements; while 440 stainless steel is used to manufacture high-hardness tools and knives, such as razor blades and scalpels.
24 Μαρ 2023 · 440c stainless steel is known for its exceptional hardness due to its high carbon content and martensitic microstructure. The hardness typically ranges from 56-60 HRC. This makes it suitable for applications where wear resistance and durability are crucial, such as ball bearings and surgical instruments. Corrosion Resistance.
