2304 Duplex Steel Pipe & Tube

2340 Duplex Manufacturing Process

Its machining is performed at low speeds, and constant feeds which help to reduce its tendency to work harden. It is tougher than stainless steel 304 and 316 due to its long stringy chip. Chip breakers are recommended. Unlike the 300 series stainless steel it requires more pressure while performing forming due to its higher yield strength. It has low ductility characteristic which tends to make it difficult to perform forming operations.Welding can be performed using most of the conventional methods such as submerged arc welding (SAW),gas–tungsten arc welding (GTAW), and gas–metal arc welding (GMAW). Hot working can be done after heating the material to 954-1093°C, which is followed rapid cooling. Annealing after working is recommended. For annealing, it has to be heated at 930-1050°Cand then rapidly quenched.

Product Details

Duplex 2304 is two-phase, ferritic, austenitic which contain chromium 23%,nickel 4%, molybdenum-free duplex stainless steel. Itscorrosion resistance properties are similar to 316L stainless steel. Furthemore it has mechanical properties twice to 304L stainless steel/316Lstainless steel grades. And this becomes helpful for the manufacturers to save weight especially for properly designed pressure vessel applications. It is particularly suitable for applications covering the -50 °C/+300 °C temperature range.
