Wear resistance of high chromium white cast iron for coal

2.2. Heat treatment The annealing of highchromium white cast iron alloys is conducted when it is necessary to machine the pieces before destabilization. This treatment is applied to obtain a soft matrix with the maximum amount of ferrite after solidifiion, creating excellent conditions for machining.

Gear Materials and Heat Treatments KHK Gears

For mating worms, iron metals such as S45C/SCM44/SCM415 are used. To prevent galling / seizure by slippage, different materials are used for each of the paired worm and worm wheel. 62 Heat Treatments What is Quenching ? Quenching is a treatment performed on steel, applying rapid cooling after heating at high temperature (Approximate 800C).

Effects of HeatTreatment on the Microstructure and Wear

The variations of microstructure and mechanical properties of a highchromium cast iron for rolls were studied from ascast to the final heat treatments. Results show that the ascast microstructure of the HCCI consists of M7C3 carbide, M23C6 carbide, martensite matrix, and retained austenite. The large dendritic M7C3 carbide surrounds the matrix, and the M23C6 carbide is mainly distributed in
