Duplex steels are made of mixed microstructure of austenite and ferrite, usually made of 50/50 mix, however in commercial alloys steel the ratio may vary to 40/60. Duplex stainless steel has approximately two times greater strength as compared to austenitic stainless steels and also enhanced resistance mainly to pitting corrosion and stress corrosion cracking.
They are consists of high chromium 19 to 32% and molybdenum up to 5%. They have lower nickel content compared austenitic stainless steels.
They are generally cost effective due to lower alloy content than similar performing austenitic steels.
