Stainless Steel Heat Exchanger Tube, ASTM A213 TP304 (1.4301, SUS304), Petrochemical Application

Grade 304, also known as 18/8 stainless steel, is the most widely used and versatile austenitic stainless steel. It contains 18% chromium and 8% nickel, which provides excellent corrosion resistance, high formability, and good mechanical properties. Grade 304 is used in a variety of applications across different industries due to its balance of strength, durability, and resistance to oxidation and corrosion.

Chemical Composition:

Mechanical Properties:

Corrosion Resistance:

• General Corrosion Resistance: Excellent resistance to a wide range of atmospheric environments and many corrosive media.
• Pitting and Crevice Corrosion: Good resistance in moderately aggressive environments, though it can be susceptible to chloride-induced pitting and crevice corrosion in chloride-containing environments.

Applications:

1. Chemical and Pharmaceutical Industry

• Chemical Containers: Used in chemical containers, transport tanks, and heat exchangers due to its resistance to various chemicals.
• Pharmaceutical Equipment: Employed in pharmaceutical production equipment and clean rooms for its non-reactive and easy-to-clean properties.

2. Water Treatment:

• Water Tanks and Pipes: Employed in water treatment facilities, storage tanks, and piping systems for its resistance to corrosion and ease of fabrication.

3. Shell and Tube Heat Exchangers:

• Tubes: Grade 304 stainless steel is commonly used for the tubes in shell and tube heat exchangers. The corrosion resistance and high strength of the material ensure durability and efficient heat transfer.
