Duplex 1.4462 round bars also have low thermal expansion and high thermal conductivity as well as high corrosion and erosion fatigue properties compared to austenite. The corrosion resistance of duplex 2205 is almost twice that of other austenitic stainless steels.
It allows manufacturers to reduce weight and make them more cost-competitive compared to duplex square bars that can be machined with high speed steel tools such as stainless steel 316L at the same feed and speed. 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. UNS S31803 and UNS S32205 are commonly referred to as Duplex 2205 materials, the “Duplex” name derived from a mixed microstructure containing approximately equal amounts of ferrite and austenite.
