Duplex stainless steel pipe


These pipe compared with ferrite, the plasticity and toughness are higher, the intergranular corrosion resistance and welding performance are significantly increased, while maintaining a ferritic stainless steel of 475 ℃ brittleness and high thermal conductivity, has the characteristics of superplasticity. Compared with austenitic stainless steel, the strength is stonger and intergranular corrosion and chlorinated stress corrosion have been improved obviously. The thermal conductivity is large, the linear expansion coefficient is small, it is suitable for the lining of the equipment and the production composite board. It is also suitable for the pipe core of heat exchanger, which is better than austenitic stainless steel.


Super Duplex stainless steel


Duplex stainless steel seamless tube has good corrosion resistance and wear corrosion. In the condition of some corrosive medium, it is suitable for making pump, valve and other power equipment.
