General Corrosion Status | Requires specific corrosion protection |
Stress Corrosion Status | Low Resistance to SCC: Table 3 Data Quality: Design Data |
EMF vs SCE | -0.61 V |
Bimetallic Corrosion | Can be used in a non-controlled environment with: Al+alloys, Cd, Sn-Pb alloys, Sn, Pb Can be used in a clean room environment with: as above and Mg, Ni, Monel,
Inconel, Ni-Mo alloys, 300 series SS, 400 series SS, Ti and Ti alloys, Zn, Be Needs specific measures: All others Test:ECSS-Q-ST-70C Rev.1 table 5.1 Data Quality: Design Data |
Machinability | Machinability is very good for this alloy in the T4 temper. In the annealed condition machinability is less good. Thus it is best to perform machining with the alloy in the T4
condition. Use of oil lubricants is recommended for all machining operations. |
Welding | The alloy may be welded, however welding heat will reduce corrosion resistance. In general welding should be avoided unless heat treatment after welding is possible to
restore corrosion resistance. Inert gas welding and resistance welding are the methods that should be used and the alloy is sensitive to cracking so fixturing needs to be
such as to reduce any strain during welding. |
Aging | This alloy is age hardenable and that occurs naturally at room temperature. |
