Summary
Experience with the sand casting of modified 9 Cr-1 Mo steel at several foundries is presented. The castings included simple blocks, elbows, valve bodies, and a steam chest. Castings were characterized by tensile and Charpy impact tests, for the effects of thermal aging on Charpy impact properties and hardness, and by creep, fatigue, and microstructure. Properties of the castings were compared with those observed for wrought material. In general, mechanical properties of castings were slightly lower than those of the wrought material.
