Abstract

Interference fits between die case, sleeves, and die inserts are critical in the operating life of a tooling. This paper makes a study of die casings made up of Maraging Steel, which failed in fatigue and die casings made up of H13 Steel which failed explosively after a few hours of assembly. The reason for random failure of these casings were investigated which revealed that H13 material had less toughness as compared to that of Maraging Steel. The other reasons were found to be stress corrosion, hydrogen embrittlement, variation in dimensioned tolerances and lack of surface integrity in the assembled components.
