Duplex 2304. also called Alloy 2304. is a molybdenum-free duplex stainless steel. It has a structure that is a balance of ferritic and austenitic and is often used as a replacement for Alloys 304L and 316L. Some of Duplex 2304 stainless steel’s other properties include:
- Outstanding corrosion resistance
- Yield strength (twice that of 304L/316L)
- Suitable for applications covering -50ºC/+300ºC temperature range
- Resistance to pitting and crevice corrosion
- Improved machinability and weldability
- Because of these positive qualities, Duplex 2304 is commonly used in a range of applications for a variety of industries.
These include:
- Pulp and paper industry (pipes, storage tanks)
- Food industry
- Pressure vessels
- Mining
- Exposure to caustic solutions and organic acids
- Water treatment
- Construction and architecture
For stainless steel to be labeled Duplex 2304. it must contain a number of different components including:
- Fe Balanced
- Cr 21.5-24.5%
- Ni 3.0-3.5%
- Mn 2.5% max
- Cu .05%-2.0%
- N .05-2.0%
- Si 1% max
