What is 316?

316 Stainless Steel is an austenitic stainless alloy known for its excellent corrosion resistance, toughness, and versatility in demanding environments. With a balanced composition including chromium, nickel, and molybdenum for enhanced resistance to pitting and crevice corrosion, 316 delivers reliable performance across marine, chemical, and industrial applications — making it a preferred choice where durability and environmental resistance are critical. It is widely used for fittings, fasteners, marine hardware, food processing equipment, and precision components that benefit from both structural integrity and corrosion resistance.

Common Questions About 316

Next day shipping is available on in-stock, qualifying orders. Fulfillment times vary for material that requires ordering from a vendor. Reach out to you rep for more information.

The primary difference is molybdenum content. 316 stainless steel offers improved resistance to:

  • Pitting corrosion
  • Crevice corrosion
  • Saltwater exposure
  • Chemical processing environments

For applications exposed to chlorides or marine conditions, 316 is typically preferred over 304.

316 stainless steel is widely used in:

  • Aerospace components
  • Defense and military hardware
  • Medical devices
  • Food processing equipment
  • Chemical processing
  • Marine applications
  • Power generation

Its corrosion resistance makes it ideal for high-performance, mission-critical parts.

In the annealed condition, 316 stainless steel is generally non-magnetic. Cold working may introduce slight magnetism.

316 stainless steel cannot be hardened through heat treatment. Strength increases are achieved through cold working processes.
