Table II - Steel Alloys

Alloy	Condition
Carbon steel (1000 series) Low-alloy steel (4130,4340 etc)      Nitronic 32                Nitronic 60   400 series Martensitic stainless steel (403, 410, 416, 431)   PH 13-8 Mo stainless steel  15-5 PH stainless steel    17-4 PH stainless steel	125 to 140 kg/mm2 UTS 125 to 140 kg/mm2 UTS All All (1) All Below H1000 (2) All

1) Tempering between 370 and 600C should be avoided because corrosion and stress-corrosion resistance is lowered.
2) H1000 = hardened above 538C (1000F).

1) Mechanically stress relieved products (TX5X or TX5XX) should be specified where possible.
2) Sheet, unmachined extrusion and unmachined plate are the most resistant forms.
3) Except for controlled tempers listed in footnote 3 of Table I, aluminium alloys. These alloys are not recommended for high-temperature applications. 66C (150F) and above.
