Stainless Steel Alloy 430

Type 430 Stainless Steel is perhaps the most popular non-hardenable ferritic stainless steel available. Type 430 is known for good corrosion, heat, oxidation resistance, and its decorative nature.

It is important to note that when well polished or buffed its corrosion resistance increases. All welding must occur at higher temperatures, but it is easily machined, bent, and formed.  Thanks to this combination it is used in a number of different commercial and industrial applications including:

  • Furnace combustion chambers
  • Automotive trim and molding
  • Gutters and downspouts
  • Nitric acid plant equipment
  • Oil and Gas refinery equipment
  • Restaurant equipment
  • Dishwasher linings
  • Element supports and fasteners

To be considered Type 430 Stainless Steel, a product must have a unique chemical composition that includes:

  • Cr 16-18%
  • Mn 1%
  • Si 1%
  • Ni 0.75%
  • P 0.040%
  • S 0.030%
