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.

FAQs & Resources

Alloy 200/201 are commercially pure Nickel alloy with 99% minimum Nickel content. Nickel is highly resistant to various reducing chemicals and is not matched in resistance to caustic alkalies including sodium hydroxide by other alloys. In addition commercially pure nickel has good magnetic and magnetostrictive properties, high electrical and thermal conductivity compared with other Nickel based alloys.

Alloy 201 is the low carbon version of alloy 200 to prevent embrittlement by intergranular Carbon graphitisation at temperatures above 315°C. Lower Carbon content reduces hardness and improves the ductility of an alloy making it suitable for cold forming and spinning etc.

Alloy 200 is used for the manufacture of processing equipment. It is particularly suitable to maintain product purity in handling foods, synthetic fibres and alkalies.

Due to its improved ductility and resistance to graphitisation the alloy is used for caustic evaporators, combustion boats, plater bars and electrical components.
