Perfect for applications in the Chemical Processing Industry

Alloy 200/201 can be used in a variety of applications, here are just a few examples:

  • Chemical Processing and Storage
  • Synthethic Fiber Production
  • Processes using caustic alkalines
  • Food Processing

About Alloy 200/201

Alloy 200/201 is extremely resistance to caustic alkalies up to and including the molten state. The extra-low carbon content of Alloy 200/201 gives virtual immunity to intergranular attack above about 315°C. The presence of chlorates must be kept to a minimum, as they accelerate the rate of attack.
