A heat exchanger is a device used to transfer heat between two or more fluids. Heat exchangers are used in both cooling and heating processes.[1] The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact.[2] They are widely used in space heating, refrigeration, air conditioning, power stations, chemical plants, petrochemical plants, petroleum refineries, natural-gas processing, and sewage treatment. The classic example of a heat exchanger is found in an internal combustion engine in which a circulating fluid known as engine coolant flows through radiator coils and air flows past the coils, which cools the coolant and heats the incoming air. Another example is the heat sink, which is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium, often air or a liquid coolant.

What is Super Duplex 2507 Stainless Steel?

The term “Super-Duplex” was first used in the 1980’s to denote highly alloyed, high-performance Duplex steel with a pitting resistance equivalent of >40 (based on Cr% + 3.3Mo% + 16N%). Stainless Steel Super Duplex 2507 is designed for applications which demand exceptional strength and corrosion resistance. The high molybdenum, chromium and nitrogen content in Super Duplex 2507 results in excellent resistance to chloride pitting and crevice corrosion attack and the duplex structure provides Super Duplex 2507 with exceptional resistance to chloride stress corrosion cracking.

Duplex family consists of:

  • Lean Duplex SS – lower nickel and no molybdenum – 2101, 2102, 2202, 2304
  • Duplex SS – higher nickel and molybdenum – 2205, 2003, 2404
  • Super Duplex – 25Chromium and higher nickel and molybdenum “plus” – 2507, 255 and Z100
  • Hyper Duplex – More Cr, Ni, Mo and N – 2707
