416 Stainless Steel Supply

416 Stainless Steel Properties

Corrosion Resistance: 416 stainless steel is known for its excellent corrosion resistance in mildly corrosive environments, including acidic and alkaline environments. It is resistant to corrosion from chemicals, solvents, and salts.

Machinability: 416 stainless steel is known for its excellent machinability due to the presence of sulfur, which acts as a lubricant during machining. It can be easily machined using automatic screw machines, lathes, and milling machines.

Weldability: 416 stainless steel is known for its poor weldability, due to its high sulfur content, which can cause cracking during welding. It is not recommended for welding, brazing, or soldering.

Ductility: 416 stainless steel has fair ductility, which means that it can be formed and shaped but is not as malleable as other stainless steel grades.

Magnetic Properties: 416 stainless steel is magnetic in all conditions.

Heat Resistance: 416 stainless steel has good heat resistance up to 760°C (1400°F). It can be used in high-temperature applications such as furnace parts and valves.

416 Stainless Steel Applications

416 stainless steel is a martensitic free-machining stainless steel with excellent machinability and good corrosion resistance. It contains sulfur, which enhances its machinability but may reduce its corrosion resistance compared to other stainless steel grades. Here are some common applications of 416 stainless steel:

  1. Machined Components: 416 stainless steel is widely used for the manufacturing of machined components such as bolts, screws, nuts, and studs. Its excellent machinability allows for efficient production of precision parts.
  2. Fasteners: Bolts, nuts, and screws used in various applications where corrosion resistance and good machinability are essential may be made from 416 stainless steel.
  3. Shafts and Axles: Components requiring good strength and machinability, such as shafts and axles in machinery and equipment, may use 416 stainless steel.
  4. Valve Components: Parts of valves and fittings, especially those requiring machining and corrosion resistance, may be made from 416 stainless steel.
  5. Firearms Components: Certain firearm components, including gun barrels, bolts, and trigger guards, may use 416 stainless steel due to its machinability and corrosion resistance.
  6. Pump and Valve Shafts: Shafts used in pumps and valves, where both corrosion resistance and machinability are important, may be made from 416 stainless steel.
  7. Electronics Manufacturing: Precision components in electronics manufacturing, such as connectors and fasteners, may use 416 stainless steel for its machinability and corrosion resistance.
  8. Food Processing Equipment: Some components of food processing equipment, including screws, bolts, and shafts, may be made from 416 stainless steel due to its machinability and corrosion resistance in mildly corrosive environments.
  9. Aircraft Parts: In certain aerospace applications where machining is critical, 416 stainless steel may be used for components such as fasteners and fittings.
  10. Cutlery and Hand Tools: Certain types of cutlery, knives, and hand tools may use 416 stainless steel for its combination of machinability and corrosion resistance.
