Abstract

The influence of phosphorous, aluminium and boron on the properties of hot-work tool steel X38CrMoV5-1 (material number1.2343) was investigated. Following impact-bending tests and notched bar impact-bending tests, phosphorous was found to be responsible for a decrease in toughness. Its embrittling influence also became clear in the investigation of continuous castability. Phosphorous was also found to cause a slight deterioration of creep rupture strength and resistance to thermal shocks. Increasing amounts of the element boron impaired toughness, and brought about a change in solidification behaviour. This resulted in a distinct deterioration of continuous castability and hot forming properties. Contents of aluminium of up to 0.096% had no influence on the properties of the hot-work tool steel investigated other than a small decrease in toughness.
