Alloy 2304 (UNS S32304) is a 23% chromium, 4% nickel, molybdenum-free duplex stainless steel. The Alloy 2304 has corrosion resistance properties similar to 316L. Furthermore, its mechanical properties, i.e., yield strength, are twice those of 304L/316L austenitic grades. Alloy 2304 is a 23% chromium, 4% nickel, molybdenum-free duplex stainless steel. The Alloy 2304 has corrosion resistance properties similar to 316L. Furthermore, its mechanical properties, i.e., yield strength, are twice those of 304/316 austenitic grades. This allows the designer to save weight, particularly for properly designed pressure vessel applications. The alloy is particularly suitable for applications covering the -50°C/+300°C (-58°F/572°F) temperature range. Lower temperatures may also be considered but need some restrictions, particularly for welded structures. With its duplex microstructure and low nickel and high chromium contents, the alloy has improved stress corrosion resistance properties compared to 304 and 316 austenitic grades.
Specification
Alloy 2304 (UNS S32304)
Standards
ASTM/ASME A240 - UNS S32304
EURONORM 1.4362 - X2 Cr Ni 23.4
AFNOR Z3 CN 23.04 Az
DIN W. Nr 1.4362
Processing
Hot Forming
Hot forming must be performed in the 1150/900°C (2100/1650°F) temperature range. After forming, a new solution annealing treatment is recommended in the 950°/1050°C (2100°/1650°F) temperature range to fully restore corrosion resistance properties and mechanical properties. Parts formed with 2304 must be supported carefully during heating to avoid creep deformation.
Cold Forming
Alloy 2304 may be cold formed without any problem. The same equipment as used for the cold forming of 304L and 316L grades can be used. Due to its higher mechanical properties, including the yield strength, higher stresses are required for cold forming. A final solution annealing heat treatment is also recommended after cold forming in order to restore the mechanical and corrosion resistance properties, as described in hot forming.
Descaling
Use the same solutions and pastes as for Alloys 304L/316L. The pickling time will be higher than for austenitic grades due to the corrosion resistance properties of the alloy.
Machinability
Alloy 2304 duplex exhibits improved machinability properties particularly when considering drilling. Its behavior is equivalent to that of 316LEZ. Furthermore, 2304 has better corrosion resistance and cleanliness properties as no sulphur additions are necessary. Localized corrosion resistance behavior is improved.
Applications
Generally where 304 and 316L are used
Pulp and paper industry (chip storage tanks, white and black liquor tanks, digestors)
Caustic solutions, organic acids (SCC resistance)
Food industry
Pressure vessels (weight savings)
Mining (abrasion/corrosion)
