PVRC Interpretive Report describes properties and fabrication characteristics of wrought and cast stainless steels used for pressure vessel construction to meet requirements of processing industries. The stainless steels are used in pressure vessel construction to meet the increasingly severe demands of modern processing industries at reasonable cost. Specific advantages are: (a) Increased corrosion resistance.(b) Elimination or reduction of product contamination.(c) Higher strength, especially at elevated temperatures (austenitic type).(d) Improved resistance to scaling.(e) Improved toughness or impact resistance at very low temperatures (austenitic type).(f) Reduced maintenance costs. Sixteen of the thirty-five standard wrought stainless steels and five of the twenty-eight standard cast stainless steels are recognized by the ASME Boiler and Pressure Vessel Code. These grades have varying degrees of heat and corrosion resistance and varying combinations of mechanical properties which make them suitable for the construction of vessels which will serve under varying conditions of corrosiveness and at temperatures from close to absolute zero to above 1500°F. Forming of all the wrought stainless steels is practical and relatively simple for shops familiar with steel construction. The austenitic types are particularly suited to welded construction. Design criteria, including controls on fabrication, are well established. Treatments to establish maximum corrosion resistance and optimum mechanical properties have been developed and standardized.
