Core performance advantages:

1. Excellent corrosion resistance

In chloride ion environments (such as seawater and chemical solutions), the pitting resistance equivalent (PREN≥35) of 2205 far exceeds that of 316L stainless steel, effectively extending the service life of equipment and reducing maintenance costs.

2. High strength and light weight

Its yield strength can reach more than twice that of ordinary austenitic stainless steel (≥450 MPa), allowing the design of thinner sections, achieving a 20%-30% weight reduction in the structure, and significantly optimizing the economic efficiency of the project.

3. Upgraded weldability and processing performance

Modern smelting technology has greatly improved the thermal processing stability of 2205 plates. With special welding materials, efficient welding can be achieved, meeting international pressure vessel standards such as ASME and PED.

Industry application expansion:

1. Energy field

Offshore platform pipelines, LNG tank linings, flue gas desulfurization systems

2. Chemical processing

Reaction vessels, heat exchanger plates, acid delivery pipelines

3. Environmental protection infrastructure

High-pressure pipelines in seawater desalination plants, aeration systems for sewage treatment

4. Transportation

Cargo holds of chemical tankers, bridge structures in high-salt environments

Market dynamics and supply:

According to the latest report of the International Metal Research Institute (MMI), the global duplex stainless steel market size is expected to exceed US$5.2 billion in 2024, with a compound annual growth rate of 6.8%. In response to market demand, leading suppliers such as Outokumpu, Sandvik, and China Taigang and Baosteel have expanded their 2205 plate production capacity, covering thicknesses from 0.5mm to 100mm, and provide customized surface treatment (2B/No.1/polishing).

Procurement advice:

Users need to pay attention to the solution treatment status of the plate and the UNS S32205/S31803 dual-standard certification to ensure that the material meets the ASTM A240/A789 standard. For extremely corrosive environments, 2507 super duplex steel can be upgraded.
