2205 duplex stainless steel is a duplex stainless steel composed of 21% chromium, 2.5% molybdenum and 4.5% nickel-nitrogen alloy. The ferrite and austenite structures each account for approximately 50%. It has high strength, good impact toughness and good overall and local stress corrosion resistance. The yield strength of 2205 duplex stainless steel is twice that of austenitic stainless steel. This feature enables designers to reduce weight when designing products, making this alloy more cost-effective than 316 and 317L. This alloy is particularly suitable for the temperature range of -50°F/+600°F. For applications beyond this temperature range, this alloy can also be considered, but there are some limitations, especially when applied to welded structures.

Compared with 316L and 317L austenitic stainless steel, 2205 duplex stainless steel has superior performance in resistance to pitting corrosion and crevice corrosion. It has high corrosion resistance. Compared with austenitic, its The coefficient of thermal expansion is lower and the thermal conductivity is higher. Compared with austenitic stainless steel, duplex stainless steel 2205 alloy has twice its compressive strength. Compared with 316L and 317L, the designer can reduce its weight. Alloy 2205 is especially suitable for the temperature range of -50°F/+600°F. Under strict restrictions (especially for welded structures), it can also be used at lower temperatures.

Duplex stainless steel casting means the castings made of duplex stainless steel. Duplex Stainless Steel (DSS) refers to stainless steel with ferrite and austenite each accounting for about 50%. Generally, the content of less phases needs to be at least 30%. In the case of low C content, the Cr content is 18% to 28%, and the Ni content is 3% to 10%. Some duplex stainless steels also contain alloying elements such as Mo, Cu, Nb, Ti, and N.

The DSS has the characteristics of austenitic and ferritic stainless steel. Compared with ferrite, it has higher plasticity and ductility, no room temperature brittleness, and significantly improved intergranular corrosion resistance and welding performance, while still maintaining brittleness, high thermal conductivity, and superplasticity as ferrite stainless steel. Compared with austenitic stainless steel, DSS has high strength and significantly improved resistance to intergranular corrosion and chloride stress corrosion. Duplex stainless steel has excellent pitting corrosion resistance and is also a nickel-saving stainless steel.

In casting production, most of the stainless steel castings are completed by investment casting. The surface of stainless steel castings produced by investment casting is smoother and the dimensional accuracy is easier to control. Of course, the cost of investment casting stainless steel parts is relatively high compared to other processes and materials.
