Stainless Steel Alloy 410 | Product Properties, Composition & Machinability
Stainless steel alloy 410 is a general-purpose martensitic stainless steel. It contains 11.5-13.5% chromium, making it corrosion resistant in mild environments. Alloy 410 exhibits high strength and hardness, making it suitable for applications in the automotive, aerospace, and manufacturing industries. It is also commonly used in cutlery and kitchen utensils due to its good combination of hardness and corrosion resistance. However, compared to austenitic stainless steels, it has limited corrosion resistance in highly corrosive environments. Alloy 410 can be heat-treated for further hardness and improved mechanical properties, making it a cost-effective choice for various industrial applications where moderate corrosion resistance and high strength are required.

Alloying Elements
Chromium: Most important element of stainless steel. An addition of 10% chromium will form an oxide film (passive surface film) which renders the steel corrosion resistant. Chromium also increases resistance to scaling.
Nickel: Second most important element. It increases ductility, corrosion resistance, scaling resistance, and high-temperature strength.
Silicon: Primarily increases resistance to scaling.
Manganese: Improves hot-working properties.
Molybdenum: Increases corrosion and high-temperature strength.
Sulfur-Phosphorus-Selenium: Increases machinability.
Titanium or Columbium-Tantalum: Stabilizes carbon and prevents chromium-carbide precipitation and subsequent intergranular corrosion.

Fabrication
Machinability ratings must be recognized as approximate values. They are a reasonable guide to relative tool life and power required for cutting. Variables of speed, cutting oil, feed, and depth of cut will significantly affect these ratios.

Machinability ratings must be recognized as approximate values. They are a reasonable guide to relative tool life and power required for cutting. Variables of speed, cutting oil, feed, and depth of cut will significantly affect these ratios.
Disclaimer: The data listed here are recommended starting points. Higher speeds and feeds may be obtainable based on the working environment. Keep in mind that speeds and feeds should always be adjusted in small steps. When using carbide tools; surface speed can be increased 2 to 3 times over the suggested values; feeds can be increased between 50 and 100%.
Characteristics
Basic martensitic type. General purpose, heat-treatable type used where corrosion is not severe.
Typical Uses
Medical and gas applications, bearings, bushings, and fasteners.
