Characteristics and Applications of Dual Phase Steel Flanges
Dual phase steel flange, also known as duplex steel flange. A steel composed of martensite or austenite with a ferrite matrix. Generally, steel composed of ferrite and austenite phases is called duplex stainless steel, while steel composed of ferrite and martensite phases is called duplex steel.
How big is the stainless steel flange generally, how to distinguish the pressure level?
Common stainless steel flanges are used in different places, so the pressure level is different to a certain extent. For example, large stainless steel stainless steel flanges are mainly used in high temperature resistant pipelines in chemical engineering, so they have a lot to do with the pressure bearing performance of their materials
