2205 / 1.4462 / S31803 / S32205 Duplex Stainless Steel Sheet & Plates
What is 2205 Duplex stainless steel?
1. Duplex stainless steel 2205 alloy is composed of 21% chromium, 2.5% molybdenum and 4.5% nickel-nitrogen alloy.
2. 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, giving this alloy a more price advantage than 316 and 317L.
3. This alloy is especially 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.
Duplex Stainless Steel refers to stainless steel with ferrite and austenite each accounting for about 50%. Generally, the content of less phases needs to reach 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 steels also contain alloying elements such as Mo, Cu, Nb, Ti, and N.
This type of steel has the characteristics of austenitic and ferritic stainless steel. Compared with ferrite, it has higher plasticity and toughness, no room temperature brittleness, and significantly improved intergranular corrosion resistance and welding performance, while still maintaining iron The 475℃ brittleness, high thermal conductivity, and superplasticity of element stainless steel. Compared with austenitic stainless steel, it 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.

The corrosion behavior of 2205 duplex stainless steel was compared with that of AISI type 316L stainless steel. 2205 stainless steel is a potential orthodontic bracket material with low nickel content (4 to 6 wt%), while 316L stainless steel (nickel content: 10 to 14 wt%) is the currently used bracket material.
Our research results show that (1) 2205 stainless steel has better corrosion resistance than 316L stainless steel; (2) when 2205 is used in conjunction with a material with poor corrosion resistance (316L stainless steel), 2205 stainless steel shows reduced corrosion; ( 3) When the anode/cathode ratio of the exposed surface area is less than 1 and 2205 is different from 316L and will not suffer from crevice corrosion, this tendency will decrease.
From the perspective of corrosion resistance, when the arch wire material is stainless steel or titanium, it seems reasonable to use 2205 as the orthodontic bracket material. Using this alloy can reduce the amount of corrosion products that patients are exposed to, thereby minimizing nickel allergies that may be associated with orthodontic treatment.
