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.
