duplex stainless steel pipe price
The Duplex Steel Pipe gets its name from the dual nature present in the microstructure of the alloy. Duplex Stainless Steel Seamless Pipe have good mechanical characteristics and can be used in an as welded condition. Considered to be superior in comparison to austenitic alloys ASTM A312 TP304 or ASTM A312 TP316, the Seamless Duplex Pipe offers much better resistance to corrosion.
Alloy 2205 duplex stainless steel plate has better pitting and crevice corrosion resistance than 316L or 317L austenitic stainless steel in almost all corrosive media. It also has higher corrosion and erosion fatigue properties as well as lower thermal expansion and higher thermal conductivity than austenite. Duplex stainless steels are extremely corrosion-resistant, work-hardenable alloys. Their microstructure consists of a mixture of austenite and ferrite phases. Therefore, duplex stainless steels exhibit the properties of austenitic and ferritic stainless steels. This combination of properties can mean some compromises compared to pure austenitic and pure ferritic grades.
