Aspects of the formation of sulfide inclusions and their effect on the quality of low-alloy structural steels

  • Published:
Metallurgist Aims and scope

Results are presented from an analysis of the mechanical properties of forgings made of low-alloy structural steels cast in a vacuum. These forgings sometimes have substandard ductility properties, which can be attributed to certain features of the formation of sulfide inclusions in them in relation to the degree of oxidation of the steel. Results are given from laboratory studies of the effect of the degree of oxidation of low-alloy structural steels on the distribution of nonmetallic inclusions in them. Aspects of the formation of oxide, sulfide, and oxysulfide inclusions during the crystallization of vacuum-degassed and non-vacuum-degassed steel are also examined.
