Heat Treatment in High Chromium White Cast Iron Ti

The influence of heat treatment on microstructure and mechanical properties of high chromium white cast iron alloyed with titanium was investigated. The austenitizing temperatures of 980°C and 1150°C for 1 hour each followed by tempering at 260°C for 2 hours have been performed and the effect of these treatments on wearAnalysis of the High Chromium Cast Iron,different hardening temperatures on the properties of high chromium cast iron were compared. The study led to systemize the literature data of the parameters of heat treatment of high chromium cast iron, and optimal conditions for heat treatment was proposed for casts ofCN104195420A - High-chrome wear-resistant cast iron,,The invention discloses a high-chrome wear-resistant cast iron material and a heat treatment method. The high-chrome wear-resistant cast iron material is prepared from iron as a main raw material, and carbon, silicon, manganese, sulphur, phosphorus, chrome, molybdenum, nickel and copper as auxiliary materials in manners of melting and
