Duplex Stainless Steel Sheet

Duplex stainless steel has developed to the third generation since its birth in the United States in the 1940s. Its main feature is that the yield strength can reach 400-550MPa, which is twice that of ordinary stainless steel, so it can save materials and reduce equipment manufacturing costs. In terms of corrosion resistance, especially under the conditions of harsh media environment (such as sea water, high chloride ion content), the pitting corrosion, crevice corrosion, stress corrosion and corrosion fatigue resistance of duplex stainless steel are significantly better than ordinary austenite Stainless steel is comparable to high-alloy austenitic stainless steel.


Duplex stainless steel has good welding performance. Compared with ferritic stainless steel and austenitic stainless steel, it is not like the welding heat-affected zone of ferritic stainless steel. Due to the severe coarsening of crystal grains, the plastic toughness is greatly reduced. Unlike austenitic stainless steel, it is more sensitive to welding hot cracks.

Processing Service Of Our Duplex Stainless Steel Sheet

  • Cutting+Slitting - Duplex stainless steel narrow strip, special length/width plate

(1) Flame cutting: The cost of flame cutting equipment is low and it is the only economical and effective means to cut thick metal plates, but it has its shortcomings in thin plate cutting.

(2) Laser cutting：Laser cutting equipment can cut stainless steel plates below 30mm. Adding oxygen to the laser beam can cut 40mm thick carbon steel, but after oxygen cutting, a thin oxide film will be formed on the cutting surface.

(3) Wire cutting: It is developed on the basis of EDM perforation and forming. It has not only developed the application of EDM but also replaced EDM perforation and forming in some aspects.

(4) Shearing cutting：Uses a moving upper blade and a fixed lower blade and uses a reasonable blade gap to apply shearing force to metal plates of various thicknesses so that the plates can be broken and separated according to the required size. Shearing machine is a kind of forging machinery, and its main function is the metal processing industry.

(5) Plasma cutting：It is a processing method that uses the heat of a high-temperature plasma arc to partially or partially melt (and evaporate) the metal at the incision of the workpiece and uses the momentum of the high-speed plasma to remove the molten metal to form an incision.

(6) Slitting: Also known as slitting, refers to the process of uncoiling, slitting, leveling, and winding of stainless steel coils into coils of the required width.
