High-chromium alloy flow components are the core wear-prone parts of equipment such as slurry pumps and mud pumps that transport solid-liquid mixed media. They mainly include the impeller, volute (pump casing), front guard plate, and rear guard plate, which are the components in direct contact with the slurry. These components are typically cast from high-chromium cast iron (such as Cr26, Cr30, etc.). By adjusting the carbon and chromium content or adding other alloy elements, they can meet the requirements for wear resistance and corrosion resistance under different working conditions.

Products features

Combination of high hardness and toughness: Through a reasonable heat treatment process, the high-chromium alloy flow components can maintain high hardness while also having certain toughness, reducing the risk of brittle rupture during use.
Strong impact resistance: Capable of withstanding the continuous scouring of concentrated slurry and material impact during the later stage of pressure filtration under high-pressure conditions.
Long service life: Under the same working conditions, the service life of high-chromium alloy flow components can be 3-5 times longer than that of ordinary materials, reducing the frequency of replacement and downtime.

Application fields

High-chromium alloy flow components are widely used in the following industries:
Main application industries:
Mining and metallurgy: tailings transportation in beneficiation plants, slurry pumping in metallurgical plants, slag treatment systems in metallurgical plants
