What Are Duplex Steel 2205 Bars?

Duplex Stainless Steel 2205 Bars are an extremely strong yet corrosion resistant stainless steel alloy known for its outstanding combination of strength and corrosion resistance. Composed primarily of chromium, molybdenum, and nitrogen elements, such as pitting corrosion resistance as well as stress corrosion cracking protection, Duplex 2205 bars find widespread application within industries including marine, chemical processing, oil & gas processing due to their excellent mechanical properties as well as resistance against harsh environments.

Duplex Stainless Steel 2205 Bars are widely renowned for their superior corrosion resistance, making them suitable for applications in harsh environments like marine and chemical industries. Composed of chromium, molybdenum and nitrogen elements for maximum resistance against stress corrosion cracking and pitting corrosion issues.

Duplex Steel Bars

Duplex Steel 2205 Bars offer moderate to good machinability. While tougher to machine compared with austenitic stainless steels, proper tooling and machining techniques can still yield satisfactory results. Their machinability is further increased by an annealed condition.

Duplex Stainless Steel 2205 Bars have outstanding weldability properties. They demonstrate great weldability across a range of standard welding processes such as GTAW, GMAW and shielded metal arc welding (SMAW), though preheating and post-weld heat treatment must be carried out correctly to avoid embrittlement or intergranular corrosion issues.

Duplex Steel 2205 Bars find numerous uses across various industries such as oil and gas, chemical processing and pulp and paper production. Common applications for Duplex 2205 bars are pressure vessels, heat exchangers, pipelines and storage tanks where corrosion resistance and mechanical strength are key considerations.

Duplex Stainless Steel 2205 Bars have become indispensable tools due to their exceptional properties, being used across numerous applications from offshore platforms and desalination plants, chemical processing equipment and automotive components to bridges, buildings and infrastructure projects requiring durability and corrosion resistance.

Manufacturing Process Of Duplex Steel Bars

Casting

Melting and Casting

Steel and alloying metals are loaded into an electric arc furnace. Once in the furnace, the metal is heated to a specific temperature above its melting point, usually in excess of 2800°F.

Forming Round Bar

Forming

Most cast steel is formed by hot rolling—the slab, bloom, or billet is heated and passed through large rollers, stretching out the steel into a longer, thinner form.

Heat Treatment

Heat treatment

Heat treatment strengthens rolled Duplex Steel by recrystallizing the deformed microstructure. Most Duplex Steel is heat treated by annealing.

Descaling

Descaling

A rolled piece of Duplex Steel acquires a layer of oxidized “mill scale,” which needs to be washed away to restore a shiny surface finish.

Cutting Round Bar

Cutting or Machining

Duplex Steel is cut to a specified shape and size. The Duplex Steel can be sheared with circular knives, sawed with high-speed blades, or blanked with punches.
