1. What is duplex stainless steel?
Ferrite and austenite each account for about 50%, and generally the content of less phases also needs to be at least 30% stainless steel.

Cr content is 18% to 28%, Ni content is 3% to 10%; some steels also contain alloying elements such as Mo, Cu, Nb, Ti, N.
2. What are the performance characteristics of dual-phase steel?
Duplex stainless steel has the advantages of ferritic stainless steel and austenitic stainless steel, both the excellent toughness and weldability of austenitic stainless steel, and the higher strength and chloride stress corrosion resistance of ferritic stainless steel Performance.

Compared with austenitic stainless steel:

1) The yield strength can reach 400Mpa ~ 550MPa, which is twice that of ordinary austenitic stainless steel;

2) Performances such as pitting corrosion resistance, stress corrosion resistance and corrosion fatigue resistance have also been significantly improved.

Compared with ferritic stainless steel:

1) High toughness, low brittle transition temperature, significantly improved intergranular corrosion resistance and welding performance;

2) Some features of ferritic stainless steel are retained, such as brittleness at 475℃, high thermal conductivity, small coefficient of linear expansion, superplasticity and magnetic properties.

Production Range:

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.
