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 casting ...
DetailsThe 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 wear
DetailsJul 18, 2013· Destabilisation (critical heat treatment) of austenite at 970°C for 2·5 h followed by annealing (subcritical heat treatment) at 600°C for 13 h results in massive precipitation of M 23 C 6 carbide particles along with spheroidised M 7 C 3. The reversed order of heat treatments leads to extensive precipitation of M 7 C 3 secondary carbide ...
DetailsHigh Chromium wear-resistant cast iron is widely used because of its excellent wear resistance. High Chromium cast iron grinding balls are widely used in cement, mining, thermal power generation, etc. To improve the production and heat treatment process of grinding balls and actively explore the relevant laws in the production process has a good …
