430 is a ferritic stainless steel with corrosion, cracking, and oxidation resistance. 430 is formed with stretch forming, bending, and drawing operations. The high carbon of 430 stainless steel gives it poor weldability and it is non-hardenable due to its straight chromium content. 430 is heated and then quickly air-cooled, a process that prevents brittleness in the metal.

430 stainless steel is widely used in a variety of products:

  • Dishwasher lining
  • Automotive trim
  • Chimney liners
  • Machine parts
  • Kitchen grade tables and utensils

Vincent Metals handles 430 in rod, sheet/strip, and foil.
