Product Introduction

1.The chromium content of 18%-22% dual-phase stainless steel has good resistance to neutral chloride stress corrosion under low stress.

2.Containing key two-phase stainless steel pipe has good corrosion resistance.

3.It has good corrosion fatigue and wear corrosion resistance, and is used in pumps, valves and other equipment under certain corrosive medium conditions.

4.Good comprehensive mechanical properties, high strength and fatigue strength, yield strength is 18-8 type austenitic stainless steel 25 times.

5.Good weldability, small hot cracking tendency.

6.Compared with austenitic stainless steel, the thermal conductivity is large and the linear expansion coefficient is small, which is also suitable for the manufacture of the tube core of the heat exchanger.
