Abstract

Seven laboratory experimental casts of 7-9% Cr Ti-bearing martensitic steels were obtained via VIM process. Plates of 25 mm thickness were produced by hot rolling. On each cast CCT diagrams and critical temperatures were determined. Several austenitizing treatments were performed to study the grain size evolution. The effect of micro structure on impact properties were finally investigated. This paper discusses the role of chemical composition on micro structural and physical properties and shows the beneficial effect either of low-temperature austenitizing or double-austenitizing steps on impact properties. © 1998 Elsevier Science B.V.
