416 STAINLESS STEEL

  • [print version]

  • Description

    416 stainless steel is a martensitic stainless steel known for its high machinability, making it the most machinable of all stainless steels, with about 85% of the machinability of free-machining carbon steel. It is primarily composed of chromium, manganese, and sulfur, which contribute to its excellent machinability and wear resistance. Machinability: Highest of any stainless steel, making it easy to cut and shape. Corrosion Resistance is moderate, suitable for dry atmospheres, fresh water, and mild alkalis, but less resistant than austenitic grades. This grade can be heat- treated to increase hardness and strength, but this may reduce its formability and weldability. Commonly used in components like screws, bolts, and pump shafts, where ease of machining and moderate corrosion resistance are required. Overall, 416 stainless steel is valued for its machinability and wear resistance, making it a popular choice in various industries.
