Duplex steel F51 / 31803 / 1.4462 Pipes and Tubes are becoming increasingly popular due to their outstanding features, like high strength, excellent corrosion, and heat resistance. They are perfect for corrosive and high-pressure environments that require optimal performance and reliability.
Duplex Steel F51 Pipes Features:
Duplex Steel F51 Pipes are known for their incredible strength, making them perfect for high-pressure conditions. They have a high resistance to crevice corrosion, chloride stress corrosion cracking, and erosion corrosion. Their excellent weldability allows them to be readily fabricated into various complex designs without diminishing their mechanical properties.

Duplex Steel 31803 Tubes Corrosion Resistance
Duplex Steel 31803 Tubes are renowned for their high corrosion resistance. They are impervious to rust and highly resist pitting, crevice corrosion, and chloride stress corrosion cracking. The tubes are easy to clean and maintain, making them ideal for high-pressure conditions in boilers, petrochemical facilities, and desalination plants.
Duplex Steel 1.4462 Pipes Chemical Composition
Duplex Steel 1.4462 Pipes contain between 22 to 23 per cent of chromium, 3 to 3.5 per cent of molybdenum, 0.1 to 0.3 per cent of nitrogen, and 1.0 to 1.5 per cent of manganese. These elements work in unison to enhance the pipes' strength, durability, and overall corrosion resistance.
Duplex Steel F51 Tubes Heat Treatment
Duplex Steel F51 Tubes undergo a process known as quenching and tempering heat treatment. The tubes are heated to high temperatures during the heat treatment to enhance their strength, durability, and overall performance. This process involves rapid cooling immediately after heating, which helps to increase the tubes' hardness and strength.
Duplex Steel F51/31803/1.4462 Pipes & Tubes are an excellent choice for environments that require high pressure, temperature, and corrosive conditions. They possess excellent corrosion resistance, heat resistance, and strength, making them the perfect solution for various petrochemical facilities, desalination plants, and marine environments.
