Duplex Stainless Steel

Duplex Stainless steel and duplex round bar is a highly sought-after alloy that has earned a lot of recognition from varying industries and manufacturing services due to its sheer strength and aesthetic appeal.


Duplex stainless steels contain two-phase microstructures of ferrite and austenite grains which offer high mechanical strength and exceptionally good resistance to corrosion.

These steels double the strength to of regular ferritic or austenitic stainless steel. Since duplex stainless steel has lower alloying content, they normally cost a lot less compared to most high alloy surcharges.

A cold rolled bar and various steels are formed and shaped from duplex stainless steel grades that will, in turn, allow for lighter constructions, less welding, and will present a more compact system to their mechanical strength.

Duplex stainless steel bars and other stainless steel products such as cold-rolled steel bar and centerless steel bars are supplied by multiple stainless steel mills for various reasons such as:

  • Lower price

  • Higher-strength

  • Price stability

  • Great corrosion resistance

  • Good toughness

  • Stress corrosion cracking resistance

  • Good weldability in thick sections

Duplex Steel Round Bar Applications

The duplex steel round bar is a type of round bar that is made from two layers of steel. It is used in a variety of industries and applications, including structural steel, oil and gas, automotive, marine, aerospace, and construction. Duplex steel round bar is a type of stainless steel bar that is used for a variety of purposes. It is a popular choice for many builders, contractors, and homeowners because it offers excellent corrosion resistance and durability.

Duplex stainless steel bar types can be found in virtually any construction project. It is used in the construction of bridges, buildings, docks, and other infrastructure projects because it has a high strength-to-weight ratio and can be easily cut with a hacksaw or shears.

They have a high strength-to-weight ratio and can be used to build structures like bridges. A duplex round bar is often used in building structures due to its high strength-to-weight ratio and excellent corrosion resistance. Duplex steel round bar is also used in manufacturing because it is strong enough to withstand the forces of friction that occur during processing without fracturing or bending.

Duplex bar supplies are also commonly used to make furniture such as stools, chairs, dining tables, and sofas. Not only that, but the duplex bar is also used for making metal furniture like bed frames, gates, or fencing panels.

The duplex stainless steel bar is also known as the “two-piece” or “double-ended” round bar because it has two ends that are nearly identical to each other, with the exception of a slight taper on one end, which allows for easier handling during fabrication.
