What are Duplex S32205 Bars?

UNS S32205 Round Bar are high-performance stainless steel bars with excellent corrosion resistance and higher strength than conventional austenitic stainless steels.
They offer good weldability and superior stress corrosion cracking resistance in chloride-containing environments, making them suitable for use in various industrial applications.

Duplex S32205 Bars Composition:

ASTM A276 F60 Duplex Round Bar comprise 22% chromium, 5-6% nickel, 3% molybdenum, and 0.22% nitrogen. Chromium and molybdenum give Duplex S32205 Bars high corrosion resistance, while nickel makes the bars ductile and strong. Nitrogen enhances the strength and corrosion resistance of Duplex S32205 Bars.

Duplex S32205 Bars Uses:

F60 round bar are used extensively in the oil and gas industry, where they are used to produce heat exchangers, pipelines, and pressure vessels. They are also used in pumps, valves, and other parts of chemical processing equipment. Duplex S32205 Bars are ideal for use in environments where corrosion, high pressure, and high temperature are a concern.

Duplex S32205 Bars Heat Treatment:

Duplex S32205 Steel Bars can be heat treated using solution annealing or annealing followed by quench and tempering. Solution annealing is conducted at temperatures ranging from 1038°C to 1120°C, followed by rapid cooling in water or air. Annealing, followed by quench and tempering, is carried out at a temperature range of 1050°C to 1150°C, followed by quenching in water or oil and tempering at 450°C to 650°C.

Duplex S32205 Bars Corrosion Resistance:

Duplex Steel S32205 Bars have high corrosion resistance, making them ideal for harsh environments. They resist pitting, crevice corrosion, and chloride-induced stress corrosion cracking. Duplex S32205 Bars are resistant to chemical attack by sulfuric, phosphoric, and acetic acid acids.

 

Conclusion:

In conclusion, F60 round bar are an excellent choice for applications that require high strength, durability, and corrosion resistance. With their unique composition and mechanical properties, these bars are widely used in the oil and gas industry and chemical processing equipment. Heat treatment and proper corrosion prevention measures can further enhance the longevity and performance of Duplex S32205 Bars.
