Carbide Wear Plate Selection Guide: Material Grade & Thickness for Mining & Construction
Table of Contents
Mining and construction equipment faces heavy abrasion, particle impact and continuous friction from ores, gravel, rock and bulk aggregates. Ordinary steel liners wear quickly, requiring frequent replacement and causing production downtime. Tungsten carbide wear plates serve as high-performance wear liners to protect equipment substrates, greatly extending service life and reducing maintenance costs. However, improper selection of carbide grade or plate thickness will lead to premature cracking or fast wear. This guide helps you select the right carbide wear plates according to your site working conditions. Before selecting carbide wear plates, analyze the following on-site parameters to avoid wrong material choices: For pure sliding abrasion, prioritize high hardness carbide. When heavy impact exists, select tougher carbide grades to prevent plate fracture. As cobalt binder content increases, carbide toughness rises but hardness and wear resistance drop. Fine grain grades are not suitable for heavy impact conditions because carbide plates may crack under repeated shock loads. Coarse grain carbide can withstand impact but wears faster under fine particle abrasion. Plate thickness directly determines usable wear volume and material cost. Common thickness ranges for carbide wear plates are 3mm, 5mm, 8mm, 10mm, 15mm and custom sizes. Tip: Do not blindly select thicker plates. If impact load exceeds the carbide grade capacity, thick carbide plates will still crack. When installing solid carbide plates, avoid direct strong welding on the carbide body to prevent thermal cracking. Composite carbide-steel plates are preferred for welded applications. A: Yes, but you need to choose coarse grain high cobalt carbide grades. For extremely heavy impact, composite carbide steel liners are recommended instead of solid carbide plates. A: We supply rectangular plates, tiles, curved plates and custom shapes according to drawings. Bolt holes, chamfers and edge treatments can be machined as requested. A: MOQ depends on plate size and machining complexity. Standard size carbide wear plates support small batch orders, and we can provide samples for performance testing.1.
