    Our innovations have led to a wide range of alloys to suit specific wear part applications, whether it be crusher parts, hammers, blow bars, valves, shell liners, or cast steel alloy parts. Specialty Alloys comprise a broad group of materials that deliver properties for more demanding applications, use more exotic or expensive materials, or require special processes to manufacture. Where standard materials may not offer desired performance, specialty alloys (including those that are modified further) may be a sensible selection. % solids, impact resistant, ceramic reinforced, epoxy/urethane hybrid coating for severe abrasive wear and impact resistance.

From the mine to the plant Coal handling systems are an integral part of a complete material flow and quality management system. Stainless steels are iron-base alloys containing % or more chro-mium. They have been used for many industrial, architectural, chemical, and consumer applications for over a half century.

Currently there are being marketed a number of stainless steels originally recognized by the American Iron and Steel Institute (AISI) as standard alloys. ABSTRACT: High chromium white cast iron alloy used in coal grinding components is a material that may present different wear resistance depending on the thermal treatment used in its manufacturing.

In this context, the properties of this alloy, containing 22% chromium and 3% carbon, were investigated after applying different heat treatments and.

This power plant had dust and spillage escaping from the coal-handling systems. To boost material-handling efficiency and reduce the risk of fire or explosion, Martin installed taller and longer skirtboard walls, new belt support systems, abrasion-resistant wear liners, and a multi-layer, low-pressure sealing system on the outside of the chute walls.

coal-handling equipment, AK Steel Ni is a more cost-effective solution to carbon and Abrasion Resistant (AR) steel due to the corrosion component of the wear process. Potential coal-handling applications include chutes, hoppers, bunkers, flooring, perforated plate for sizing, flight conveyor wear liners, vibrating screen pans.

I am looking for approximate relative wear lives of various wear resistant materials, such as ceramics, AR plate, Ni-Hards, chrome carbides, UHMW's, etc. I want to use the relative wear lives combined with the cost differences and ease of installation to choose the optimum wear liner material for coal handling chutes.
