Weldability of duplex stainless steel
The weldability of duplex stainless steel combines the advantages of austenitic steel and ferritic steel, and reduces their respective deficiencies.
1) The sensitivity of hot cracks is much smaller than that of austenitic steel;
2) The sensitivity of cold cracking is much smaller than that of general low alloy high strength steel;
3) After the heat-affected zone is cooled, more ferrite is always retained, thereby increasing the corrosion tendency and the sensitivity of hydrogen-induced cracks;
4) Duplex stainless steel welded joints may precipitate δ phase embrittlement. δ phase is an intermetallic compound of Cr and Fe. Its formation temperature range is 600～1000℃. Different steel types have different temperatures to form δ phase;
5) Duplex stainless steel contains 50% ferrite, and also has brittleness at 475℃, but it is not as sensitive as ferritic stainless steel;

Why choose us:
1. All pipe fittings are strictly implemented in accordance with the standards, accept any third-party inspection, and return service.
2. Before leaving the factory, 100% dimensional inspection, 100% spectral test, mechanical and mechanical performance test, pickling, pickling process are mainly aimed at the removal of surface grease and harmful substances, complete surface passivation to prevent oxidation. Some suppliers have not implemented ( Because the surface is not visible to the naked eye after sandblasting) annealing and solid solution (heat treatment), many goods on the market are not heat-treated. When the pipe fittings are in some cold or hot environments, the seam will slowly crack if it is not heat-treated. This process is invisible to the naked eye, surface sanding (many relatively inexpensive processes on the market), bevel ends, etc.
3. Normally, the individual weight of our company's pipe fittings is heavier than that on the market, (Ensure the back arc thickness) to avoid the parts of the same wall thickness that cannot be seen by the naked eye after the processing The pressure is guaranteed, because many suppliers choose the material to the maximum limit in order to minimize the cost.
