The stainless steel heat exchanger tube is composed mainly of iron, chromium (10-30%) and nickel, which is usually supplemented with molybdenum for increased corrosion resistance. Its mechanical properties include high tensile strength (up to 750 MPa) and yield strength (205-310 MPa) to ensure tubing durability under pressure. The smooth surface provides excellent heat transfer and reduces fouling. Benefits include exceptional corrosion and heat resistance, making it ideal for harsh environments. Stainless steel heat exchangers are widely used in the chemical industry, oil and gas, and HVSC for reliable and efficient thermal applications.
