Machining Duplex Stainless Steel. However research on this matter is rather limited. Duplex steels are somewhat more difficult to machine than the conventional austenitic grades such us type 316. This austenitic-ferritic - Duplex provides excellent corrosion resistance particularly stress corrosion cracking corrosion fatigue and erosion and ensures high strength. Even though the machining distance used in the trials is considered to be relatively short the tested tools suffered extended damage and wear exemplifying how difficult it.
This austenitic-ferritic - Duplex provides excellent corrosion resistance particularly stress corrosion cracking corrosion fatigue and erosion and ensures high strength. Sanmac 2205 is a 22 Cr duplex stainless steel with improved machinability as standard. Its kinda like a combo of inconel and monel. The term Duplex refers to the two-phase. However the lean duplex grade S32101shows excellent machinability 3. Advertentie See our Forta range Stainless Steels for corrosive environments.
Here is some info from macsteel on 2205 duplex.
Duplex Stainless Steels are specified due to the high proof strength and resistance to corrosion particularly Stress Corrosion Cracking due to the lower Nickel content in their makeup they are often cheaper than other grades with similar properties and their price more stable. The difficulties in the machining of duplex stainless steel are well known. The machined surface becomes harder at the same time as tool-life decreases. I machine cylinders that are made out of spun cast super duplex stainless steel its very abrasive. Duplex steels are somewhat more difficult to machine than the conventional austenitic grades such us type 316. However research on this matter is rather limited.
