Abstract

The influence of heat treatment and chemical composition on the microstructure and properties of high strength low alloy (HSLA) cast steels has been determined. This new family of cast alloys is similar in composition and properties to the widely used wrought HSLA steels. However, for the HSLA cast steels, heat treatment alone rather than thermomechanical treatment is used to develop a fine grain size and to control precipitation strengthening. Compositions are based on low carbon C-Mn-Mo alloys with V and/or Nb microalloy additions. Both carbon content and microalloy addition levels strongly influence properties and heat treatment response. Desirable properties can be achieved for quench & temper, normalize & temper, and special intercritical heat treatments. Intercritical heat treatment in particular results in excellent low temperature impact toughness.
