Product Details of Duplex 2205 Stainless Steel Round Bars:

Medium alloy duplex stainless steel UNS S31803, also known as 2205, is a duplex stainless steel. UNS S31803 is an American standard and is made of duplex stainless steel. It is the most common steel grade used in two-way steel in the world. It is resistant to curing hydrogen, carbon dioxide and chloride environments. It can be formed by hot and cold processing. It has good welding performance. It is suitable for use as a structural material instead of 304 and 316. . The main component of 2205 duplex stainless steel: 22Cr-5Ni-3Mo-0.15N. National standards: NAS 329J3L, UNS S32205/S31803, DIN/EN 1.4462, ASTM A240, ASME SA-240. Mechanical properties: tensile strength: σb≥640Mpa; elongation: δ≥25%. Typical working conditions: 20% dilute sulfuric acid, below 60℃, annual corrosion rate <0.1mm; matching welding wire: ER2209.

The process flow of the 2205 stainless steel bar production line: 

billet acceptance → heating → rolling → double-length cutting → cooling → cutting → inspection → packaging → measurement → storage.

Overview of 2205 Duplex Steel

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, 2205 duplex stainless steel has twice its compressive strength. Compared with 316L and 317L, the designer can reduce its weight. 2205 duplex stainless steel 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.

The yield strength of 2205 duplex stainless steel rods is more than twice that of ordinary austenitic stainless steels. This feature enables designers to reduce weight when designing products, making this alloy more cost-effective than 316 stainless steel rods and 317L stainless steel rods. 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.

Application of 2205 duplex stainless steel

· Pressure vessels, high-pressure storage tanks, high-pressure pipelines, heat exchangers (chemical processing industry).
