Features of Duplex Stainless Steel Casting

• Strength: Duplex stainless steel castings are about twice as strong as regular austenitic or ferritic stainless steel castings.
• Toughness and ductility: Duplex stainless steel castings have significantly better toughness and ductility than ferritic stainless steel castings; however, they do not reach the excellent values of austenitic stainless steel castings.
• Corrosion resistance: As with all stainless steels, corrosion resistance depends mostly on the composition of the stainless steel castings. For chloride pitting and crevice corrosion resistance, their chromium, molybdenum and nitrogen content are most important. Duplex stainless steel casting grades have a range of corrosion resistance, similar to the range for austenitic stainless steel castings, i.e from Type 304 or 316 to 6% molybdenum stainless steel castings.
• Stress corrosion cracking resistance: Duplex stainless steels show very good stress corrosion cracking resistance, a property they have “inherited” from the ferritic side. Stress corrosion cracking can be a problem under certain circumstances (chlorides, humidity, elevated temperature) for standard austenitic castings such as Types 304 and 316 stainless steel castings.
