2. A 572 Gr. 50
3. AISI 1018 / 1020
4. AISI 1018 / 1026
Pipe Sealing structural materials and bolt ( remain inside the pipe in the corrosive environment and resist different forces)
5. A 513
6. A 514 Gr. B or H
7. A 517 Gr. B or H
8. A / SA 574
9. AISI 4140 / 4142

For most of these materials it will depend on their specific thermo-mechanical condition. There are hardness limits for many materials.
