Cromgard® C21

At 20.5-23.5-percent chromium, it has better corrosion resistance than Type 304L in most applications and performs as well as Type 316L in many environments while at the same time having the higher strength characteristics of duplex stainless steels. The yield strength of Cromgard® C21 is more than double that of austenitic stainless steels such as grades 304L and 316L. This strength advantage often allows downgauging in the design, depending on Young’s Modulus and buckling limitations.

Cromgard® C21’s excellent strength, toughness, corrosion resistance and resistance to stress corrosion cracking (SCC) make it suitable for applications such as:

  • subsea oil & gas
  • top side oil & gas
  • pipes & tubes
  • storage tanks
  • power generation
  • transport tanks
  • heat exchangers
  • cosmetic architectural
  • structural architectural
