Abstract

Abstract: Through a series of heating temperature， holding time tests and detection of precipitated phases， the austenite grain growth of SXQ500/550DZ35 steel for hydropower station is studied. It is determinted that recommended temperature for complete austenitization is 900-950 ℃， and the recommended holding time is 20-60 min. The purpose is to ensure its low temperature impact toughness by refining grain steel， and to provide relevant basis for the improvement of later heat treatment process.
