Duplex Steel S32304/2304 stainless steel sheet/plate
Product Description
 
Stainless steel grade Duplex 2304 is a duplex stainless steel type with a structure that is a balance of ferritic and austenitic. It has high strength and toughness, resistance to stress corrosion cracking, high thermal conductivity, low thermal expansion, and easy fabrication. It is recommended that this steel is not used in areas where the steel would be exposes to temperatures over 1058°C (570°F) for prolonged periods.

Manufacturing Process
Machining of stainless steel grade Duplex 2304 is performed at low speeds, and constant feeds help to reduce its tendency to work harden. This material is tougher than grade 304 and 316 stainless steels due to its long stringy chip. Chip breakers are recommended. Unlike the 300 series stainless steel, Duplex 2304 steel requires more pressure while performing forming due to its higher yield strength. Its low ductility characteristic tends to make it difficult to perform forming operations.
 
Welding can be performed using most of the traditional methods such as gas-tungsten arc welding (GTAW), submerged arc welding (SAW), and gas-metal arc welding (GMAW). The filler metal should be a balanced of ferrite/ austenite type like 2205 or 2304.
 
Hot working can be done after heating the material to 954-1093°C (1750-2000°F), which is followed rapid cooling. Annealing after working is recommended. For annealing, the material is heated to 930-1050°C (1710-1920°F) and then rapidly quenched.
 
Applications
Stainless steel grade Duplex 2304 is used by various industries including pulp and paper, coal handling, potash, food and beverage, and waste water.
 
The specific applications are as follows:
Bridges
Storage tanks
Water heaters
Heat exchangers
