Effects of heat treatment and tracer element impurities on the impact properties of the 12Cr steels
Description
The addition of sulfur up to 0.05% embrittles HT-9 steels by decreasing the upper shelf energy. Sulfur has little or no effect on the DBTT. The addition of up to 0.05% phosphorous decreases the upper shelf energy but has no effect on the DBTT. The addition of copper up to 0.15% decreases the upper shelf energy but has no effect on the DBTT. Effects of heat treatment on microstructure and ductile-brittle transition temperature of HT-9 were also investigated
