4This is the maximum design temperature for water service construction. Several ASME Code Cases govern additional usage:
     a) Per Section I Code Case 2665, 1300°F (704°C) is the maximum design temperature for molten nitrate salt wetted construction.
     b) Per Section I Code Case 2756, autogenous welds can be used in the design range of 1000°F and 1250°F (538-677°C).
     c) Weld strength reduction factors are governed by Section I PG-26 and Code Case 2805.    
5Section VIII Division 1 Code Case 2671 contains an external pressure chart for 1800°F (982°C).  
6For any bolts created from this material, 1650°F is the maximum design temperature. See Section VIII Division 1 Code Case 2775.
7B16 Case 5 allows for higher pressure-temperature ratings for valves made of this material.
