The most popular duplex (ferritic/austenitic) stainless steel grade is duplex steel 2205 plates, commonly known as UNS S32205 plates. Due to their excellent corrosion resistance and high strength, the Duplex 2205 plates, sheets, and coils that we offer to find use in a variety of industries. They are produced using high-quality standard raw materials and are designed in accordance with regional, national, and international regulations. Forging temperatures for these duplex 2205 plates should range from 1100°C to 1250°C, with the same temperature being raised and cooled as needed. Duplex Steel UNS S32205 Perforated Sheets are a two-phase, ferritic, and austenitic steel with 22% chromium, 3% molybdenum, and 5%–6% nickel alloy content.
Although the corrosion resistance of duplex steel 2205 plates is better assured, the majority of currently produced duplex steel S31803 also conforms to duplex steel S31803. In the interim, we manufacture premium Duplex Steel 2205 Sheets with a mixed austenite and ferrite microstructure, with the goal of achieving a 50/50 blend, despite the fact that in commercial composites, the blend may be 40/60 separately.

Duplex Stainless Steel Plate General Properties
Alloy 2205 duplex stainless steel plate is a nitrogen alloyed duplex stainless steel plate with 22% chromium, 3% molybdenum, and 5-6% nickel. It has strong generalized, localized, and stress corrosion resistance qualities in addition to high strength and outstanding impact toughness.
In practically all corrosive conditions, alloy 2205 duplex stainless steel plate offers superior pitting and crevice corrosion resistance than 316L or 317L austenitic stainless steels. Additionally, it possesses higher thermal conductivity and lowers thermal expansion than austenitic, as well as high corrosion and erosion fatigue properties.
When compared to austenitic stainless steels, the yield strength is roughly twice as high. As a result, the alloy is lighter and more cost-effective when compared to 316L or 317L.
A duplex stainless steel plate made from alloy 2205 is best suited for applications requiring a temperature range of -50°F to +600°F. Temperatures outside of this range might be taken into consideration, but they need to be limited, especially for welded constructions.
Advantages Of Duplex Stainless Steel Plates
Duplex One of the most sought-after commodities in the sector is stainless steel. This duplex 2205 plate's key benefit is that it performs more cost-effectively than other types of alloys. At its price point, there are no substitutes for its strength and corrosion resistance. These plates combine the advantageous qualities of ferritic and austenitic grades. They can be successfully welded using conventional welding techniques. This grade's main drawback is its poor impact toughness at low temperatures. In addition, they are not advised to labor in temperatures between -50 and 250 degrees Celsius.
