What steel is used in heat exchangers?

Stainless steel is commonly used in heat exchangers due to its corrosion resistance and ability to withstand high temperatures. Some common grades of stainless steel used in heat exchangers include:

Austenitic Stainless Steel: Grades like 304 (S30400) and 316 (S31600) are widely used due to their good corrosion resistance and thermal conductivity.

Duplex Stainless Steel: Grades like 2205 (S32205) offer a combination of high strength and excellent corrosion resistance, making them suitable for more demanding applications.

Ferritic Stainless Steel: Grades like 409 (S40900) are used for specific applications where high-temperature resistance is required.

The choice of steel depends on various factors such as operating conditions, fluid properties, and budget constraints. Other materials like carbon steel, titanium, and nickel alloys are also used in heat exchanger construction based on specific requirements.
