Tube stainless steel Sanmac® 2205

aeronautical

Sanmac® 2205 is a duplex (austenitic-ferritic) stainless steel with improved machinability. The grade is characterized by: Excellent machinability High resistance to stress corrosion cracking (SCC) in chloride-bearing environments High resistance to stress corrosion cracking (SCC) in environments containing hydrogen sulfide High resistance to general corrosion, pitting and crevice corrosion High mechanical strength – roughly twice the proof strength of austenitic stainless steels Good hot-working properties High resistance to erosion corrosion and corrosion fatigue Physical properties that offer design advantages Good weldability Standards UNS: S31803, S32205 EN Number: 1.4462 EN Name: X2CrNiMoN22-5-3 Product standards EN 10216-5, EN 10297-2, EN 10294-2 ASTM A790 Approvals Approved by the American Society of Mechanical Engineers (ASME) for use in accordance with ASME Boiler and Pressure Vessel Code, section VIII, div. 1 and section VIII, div. 2, Case 2067-2 NACE MR 0175 (sulfide stress cracking resistant material for oil field equipment)
