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 317/317L Stainless Steel?

317 is a higher chromium, nickel and molybdenum version of 316 stainless designed principally for increased strength and corrosion resistance when compared with 304/304L and 316/316L.

317L is similar to 316 stainless steel but provides improved resistance to atmospheric corrosion, to many organic and inorganic chemicals and to food and beverages and can produce stronger welds due to the low carbon content. 317L’s molybdenum content increases to 3 to 4% from the 2 to 3% found in 316 and 316L. It has the same high strength and corrosion resistance as 317 steel but can produce stronger welds due to the low carbon content.

Alloy 317LMN and 317L are molybdenum-bearing austenitic stainless steel tube with greatly increased resistance to chemical attack as compared to the conventional chromium-nickel austenitic stainless steel pipe such as Alloy 304. In addition, 317LMN and 317L alloys offer higher creep, stress-to-rupture, and tensile strengths at elevated temperatures than conventional stainless steels. All are low carbon or “L” grades to provide resistance to sensitization during welding and other thermal processes. Grade 317L is austenitic stainless steel that provides improved corrosion resistance over 304L and 316L stainless steels. The low carbon provides resistance to sensitization during welding and other thermal processes. 317L is non-magnetic in the annealed condition but may become slightly magnetic as a result of welding.

The “M” and “N” designations indicate that the compositions contain increased levels of molybdenum and nitrogen respectively. The combination of molybdenum and nitrogen is particularly effective in enhancing resistance to pitting and crevice corrosion, especially in process streams containing acids, chlorides, and sulfur compounds at elevated temperatures. Nitrogen also serves to increase the strength of these alloys. Both alloys are intended for severe service conditions such as flue gas desulfurization (FGD) systems.

In addition to excellent corrosion resistance and strength properties, the Alloys 316, 316L, and 317L Cr-Ni-Mo alloys also provide the excellent fabricability and formability which are typical of the austenitic stainless steel tubing .
