Harsh Metalloys, a leading manufacturer and supplier based in Mumbai, India, offers top-quality Stainless Steel Heat Exchanger Tubing for a wide range of industrial and commercial applications. These tubes are engineered for exceptional performance in heat transfer systems, providing superior resistance to corrosion, scaling, and high temperatures. Manufactured using premium stainless steel grades like 304, 316L, 321, and 347, our heat exchanger tubes meet global standards such as ASTM A213, A269, and A249. With precise dimensional tolerances, smooth internal surfaces, and excellent mechanical strength, Harsh Metalloys ensures reliable and efficient tubing solutions for critical thermal exchange operations.
Stainless Steel Heat Exchanger Tubes are primarily made from corrosion-resistant alloys containing chromium (18–20%), nickel (8–14%), and molybdenum (2–3%) depending on the grade. These elements provide excellent mechanical properties, such as high tensile strength (500–750 MPa), yield strength (200–450 MPa), and superior thermal conductivity. The tubing undergoes cold drawing and annealing for enhanced grain structure and surface finish. Harsh Metalloys ensures tight wall thickness control, smooth bore, and consistent mechanical performance to meet the high demands of heat transfer efficiency, pressure handling, and extended service life in aggressive environments.
