ADVANCED PRESSURE VESSEL MATERIALS.
Data on 5Cr - 3Mo - 12Ni alloy, PH13 - 8Mo and Iconel 718 for pressure vessel application are given. The 5Cr - 3Mo - 12Ni posseses characteristics suited to uniform aging of heavy sections. Tensile and toughness properties are good, and structural stability up to 315 deg C is adequate. Weldability with 12Ni - 3Cr - 3Mo filler material is good but 12Ni - 5Cr - 3Mo filler is more efficient. Aging characteristics of PH13 - 8Mo may not be suited to uniform aging of heavy sections. Excellent tensile properties and good toughness can be developed. The alloy is structurally stable at long time heating at 425 deg C. Good weldability with filler metal of matching composition was exhibited but weld ductility and toughness are only fair. (F.S.)
