Stainless Steel Super Duplex Round Bar

Product Details:

Alloy 20 is a type of stainless steel that is commonly used in various industrial applications, particularly in environments where corrosion resistance is critical. It contains nickel, chromium, molybdenum, and copper, which give it excellent resistance to sulfuric acid and other corrosive substances.

A round bar made of Alloy 20 would typically be used in situations where strength and corrosion resistance are required, such as in chemical processing equipment, tanks, valves, pumps, and piping systems.

When purchasing Alloy 20 round bars, it's essential to specify the diameter, length, and any additional specifications required for your particular application. These bars are available in various sizes and can be custom-made to meet specific requirements.

It's always recommended to consult with a materials specialist or supplier to ensure you select the appropriate grade and size of Alloy 20 round bar for your project's needs. Additionally, consider factors such as tolerances, surface finish, and any special heat treatment requirements based on the application.

Stainless Steel 32760, also known as Super Duplex Stainless Steel or UNS S32760, is a highly alloyed duplex stainless steel with exceptional corrosion resistance and mechanical properties. It is characterized by its high strength, superior resistance to corrosion in harsh environments, and excellent weldability. Super Duplex Stainless Steel round bars are commonly used in applications where corrosion resistance, high strength, and durability are essential, such as in offshore oil and gas platforms, chemical processing, and marine engineering. Here's a detailed description of Stainless Steel 32760 Super Duplex round bars:

1. Composition: Stainless Steel 32760 Super Duplex round bars typically contain about 25% chromium, 7% nickel, 3.5% molybdenum, and 0.25% nitrogen, along with varying amounts of other alloying elements such as copper and tungsten. This high alloy content contributes to its exceptional corrosion resistance and mechanical properties.

2. Corrosion Resistance: Stainless Steel 32760 Super Duplex exhibits outstanding corrosion resistance in a wide range of corrosive environments, including seawater, chloride-containing solutions, acids, and alkaline media. It offers superior resistance to pitting, crevice corrosion, and stress corrosion cracking compared to standard austenitic and duplex stainless steels.

3. High Strength: Stainless Steel 32760 Super Duplex round bars offer high strength and toughness, with significantly higher yield strength and tensile strength compared to conventional austenitic and duplex stainless steels. This high strength makes it suitable for structural components and equipment subjected to heavy loads and high-stress conditions.

4. Weldability: Stainless Steel 32760 Super Duplex round bars have good weldability when appropriate welding procedures and filler materials are used. However, care should be taken to control heat input and interpass temperature to minimize the risk of sensitization and preserve the corrosion resistance of the welded joints.

5. Applications: Stainless Steel 32760 Super Duplex round bars find use in various industries and applications, including:

   • Offshore oil and gas: Subsea pipelines, offshore platforms, and equipment exposed to aggressive seawater environments.
   • Chemical processing: Heat exchangers, pressure vessels, and piping systems handling corrosive chemicals.
   • Marine engineering: Shipbuilding, desalination plants, and marine structures requiring high corrosion resistance and strength.
   • Pulp and paper industry: Digesters, evaporators, and bleach plants in pulp and paper processing facilities.

6. Surface Finish: Stainless Steel 32760 Super Duplex round bars are available in various surface finishes, including black finish (as hot rolled), pickled, bright annealed, and polished finishes, depending on the application requirements.

7. Customization: Stainless Steel 32760 Super Duplex round bars can be custom-cut to specific lengths and diameters according to customer requirements. They are available in different sizes and grades to suit various applications.

8. Standards and Specifications: Stainless Steel 32760 Super Duplex round bars are typically manufactured to meet industry standards such as ASTM A276, ASTM A479, and ASTM A182, ensuring quality and consistency.
