Duplex 2304 2205 Stainless Pipe

The chemical composition of stainless steel grade Duplex 2304 is outlined in the following table.

Duplex 2304 2205 stainless pipe

Alloy 2304 (UNS S32304) is a 23% chromium, 4% nickel, molybdenum-free duplex stainless steel. Alloy 2304 has corrosion resistance properties similar to 316L. In addition, its mechanical properties, namely yield strength, are twice those of 304L/316L austenitic grades. This enables designers to reduce weight, especially for properly designed pressure vessel applications. Alloy 2304 is a 23% chromium, 4% nickel, molybdenum-free duplex stainless steel. Alloy 2304 has corrosion resistance properties similar to 316L. Additionally, its mechanical properties, namely yield strength, are twice those of 304/316 austenitic steels. This enables designers to reduce weight, especially for properly designed pressure vessel applications.
2205 duplex stainless steel is a duplex stainless steel composed of 22% chromium, 3% molybdenum and 5-6% nickel nitrogen. It has high strength, good impact toughness and good overall and local resistance to stress corrosion. Compared with 316L and 317L austenitic stainless steel, 2205 alloy has superior performance in resisting pitting corrosion and crevice corrosion. It has high corrosion resistance. Compared with austenite, its thermal expansion coefficient is lower and its thermal conductivity is Sex is higher. The yield strength of 2205 is twice that of austenitic stainless steel. This feature allows designers to reduce weight when designing products, making this alloy more cost-effective than 316 and 317L. This alloy is particularly suitable for use in the -50°F/+600°F temperature range. For applications outside this temperature range, this alloy can also be considered, but there are some limitations, especially when used in welded structures.
