behaviour of a 15 % chromium white cast iron used for ball mill production. decisive role for the heat-treated high-chromium cast iron properties.

ABSTRACT: High-chromium white cast iron contains chromium carbides that provide excellent wear resistance, but also cause poor fracture properties. Heat 

The treatment consists of heating the castings to 480-540°C for 8-12 hours, but the temperature and the time at the temperature have important bearings on properties. Excess time or temperature may soften the castings with drastic reduction in the abrasion resistance; whereas, insufficient temperature does not eliminate the austenite completely.

As high chromium irons are quite brittle, the castings are heated slowly in a cold furnace to 650°C to avoid thermal cracking (as these are bad conductors of 

The invention discloses a heat-treatment method of high-chromium wear-resistant white cast iron Cr28. According to the invention, high-chromium 

The annealing of high-chromium white cast iron alloys is conducted when it is necessary to machine the pieces before destabilization.

High chromium white cast irons must be heat treated to develop the full hardness and maximum wear resistance. The destabilization (hardening) heat treatment is 

High-chromium white cast irons are used extensively in the mining, age-hardening heat treatment during which secondary carbide precipitation occurs 

Process/ Alloy has been developed for the production of high chrome high carbon cast iron with improved wear resistance. Heat Treatment has been optimized to get better wear resistance. Oil temperature and viscosity of the oil have been optimized to have a faster quenching rate and also to achieve distortion-free grinding media.
