Duplex stainless steel pipe price per ton

On average, duplex stainless steel is about twice as strong as either ferritic or austenitic stainless steels. High toughness and ductility. Duplex stainless steel can be more easily formed under pressure than ferritic grades and also have superior toughness.

Content

Duplex steel pipes have a mixed microstructure with roughly equal proportions of ferrite and austenite. UNS S32205 pipes are a family of grades whose corrosion properties depend on their alloy content.

 

These UNS S32205 pipe provide a balance of properties resulting from their duplex metal structures. The mixed ferritic-martensitic structure of the 409LNi provides better strength and hardness compared to the straight ferritic materials and better sinterability and ductility compared to the martensitic alloys.

 

In addition, UNS S32205 pipes are mainly used in piping systems that transport fluids or gases. We manufacture steel pipes from alloy steels that contain nickel and chromium, which give ASTM A790 UNS S32205 Duplex Stainless Steel Pipe the corrosion-resistant properties. Stainless steel tubing resists oxidation, making it a low-maintenance solution for high temperature and chemical applications. Due to its ease of cleaning and sterilization, 2205 tubing is also suitable for applications involving food, beverage and pharmaceutical applications.

 

ASTM A790 Seamless Pipes have improved strength over austenitic stainless steels and also improved resistance to localised corrosion, particularly pitting, crevice corrosion and stress corrosion cracking. They are characterised by high chromium (19–28%) and molybdenum (up to 5%) and lower nickel contents than austenitic stainless steels. The chemical composition based on high contents of Cr and Mo, improves intergranular and pitting corrosion resistance, respectively. Additions of nitrogen can promote structural hardening by interstitial solid solution mechanism, which raises the yield strength and ultimate strength values without impairing toughness.

 

When welding duplex alloys, the heat input and interpass temperature must be controlled to maintain the ferrite-austenite balance. Otherwise, the advantages of using the duplex material will be lost. The time spent at 1,300 °F to 1,800 °F must be controlled. The heat-affected zone (HAZ) time-at-temperature is critical in controlling the intermetallic phases.
