Properties of Stainless Steel

Stainless steel castings are ideal for a variety of applications thanks to stainless steel's advantageous properties:

  • Minimum of at least 10% chromium
  • Contains a thin passivation layer of chromium (III) oxide, making the metal shiny
  • Extra layer protects the underlying metal from the elements
  • Scales at 1300 degrees F, or 704 degrees C
  • Easily fabricated
  • Can be welded with traditional techniques

Cast Stainless Steel Grades Commonly Used in Industrial and Marine Applications

The level of corrosion resistance, as well as the mechanical properties and cost should be considered when developing stainless steel investment castings to ensure cost-effectiveness, performance and longeivty for a particular application. 

Common grades of stainless steel used in industrial and marine applications include: 

  • 304 Stainless Steel: Also known as 18-8 stainless steel, it contains 18% chromium and 8% nickel. Grade 304 stainless steel is appreciated for its corrosion resistance and formability.
  • 316 Stainless Steel: 316 contains 16-18% chromium, 10-14% nickel, and 2-3% molybdenum. Grade 316 stainless steel is particularly resistant to chemical corrosion & acidic and salty environments. 

Other stainless steel grades, such as 316L, 317, and 2205 (Duplex Stainless Steel), are also used in specific industrial and marine applications based on the project's unique requirements.
