SAE 316 Stainless Steel Composition

SAE 316 stainless steel, is among the most popular types of stainless steel used today. This type of steel contains 10 percent nickel and 18 percent chromium, allowing it to retain its tensile strength even at extremely high temperatures. The nickel also provides excellent stress cracking resistance and helps maintain dimensional stability during welding. For these reasons, SAE 316 stainless steel is often used in various underwater and chemical processing applications where resistance to highly corrosive or caustic environments is required.

SAE 316 Stainless Steel Properties

SAE 316 stainless steel offers excellent corrosion resistance, even in chloride-rich environments. It also has good weldability, formability, and toughness when cold-worked or heated. The mechanical properties of SAE 316 stainless steel can vary depending on the heat treatment applied, but at room temperature, it typically has a tensile strength between 520MPa and 800MPa (75 ksi to 116 ksi). Its yield strength is between 275MPa to 550MPa (40 ksi to 80 ksi), and its elongation ranges from 30% to 40%.

  • SAE 316 stainless steel is an austenitic chromium-nickel stainless steel with superior corrosion resistance to other chromium-nickel steels, such as 304 stainless steel.
  • In addition, 316 stainless steel is also resistant to pitting and crevice corrosion in chloride environments.
  • SAE 316 stainless steel has a higher nickel content and molybdenum for even greater corrosion resistance.
  • SAE 316 stainless steel is widely used in the food and medical industries for its high level of sanitation and cleanliness.
  • SAE 316 stainless steel is also commonly used in the marine environment due to its ability to resist saltwater corrosion.
