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 309S/309H Stainless Steel?

Alloy 309 (UNS S30900) is an austenitic stainless steel developed for use in high temperature corrosion resistance applications. The alloy resists oxidation up to 1900°F (1038°C) under non-cyclic conditions. Frequent thermal cycling reduces oxidation resistance to approximately 1850°F (1010°C). A chromium-nickel stainless grade, Alloy 309/309S is suitable for a number of high temperature applications. 23% chromium, approx. 5% more than 304 stainless steel gives Alloy 309/309S an edge over 304 stainless steel when it comes to general corrosion resistance at elevated temperatures.

AISI 309S stainless steel is an austenitic stainless steel formulated for primary forming into wrought products. Cited properties are appropriate for the annealed condition. 309S is the AISI designation for this material. S30908 is the UNS number. It contains less nickel in its composition than Type 310, moderately low tensile strength and  lower amount of carbon in its composition among the wrought austenitic stainless steels thus utilization in areas where high temperature gases may pose a problem. Type 309S is additionally characterized by its resistance to oxidation and creep, along with its ability to withstand high temperatures. Moist environments have no effect on it, due to the higher levels of nickel and chromium in its makeup. Because of this, it is often utilized in marine environments in place of Stainless Steel 304, as it displays a higher resistance. Despite its excellent weldability, Type 309S does have a tendency to work harden.

AISI 309H (S30909) Stainless Steel. AISI 309H stainless steel is an austenitic stainless steel formulated for primary forming into wrought products. Cited properties are appropriate for the annealed condition. 309H is the AISI designation for this material. S30909 is the UNS number. It has a moderately low tensile strength
