Understanding Steel Sheet
A steel sheet is a flat steel material that is cast with steel molten liquid and pressed after cooling. Steel sheets are flat, rectangular, and can be directly rolled or cut from wide steel strips. According to thickness from steel sheet exporter-Steel Searcher, steel sheets are divided into thin steel sheets less than 4mm (thinnest 0.2mm), medium-thick steel sheets from 4 to 60mm, and special-thick steel sheets from 60 to 115mm. Steel sheets are divided into hot rolled steel sheet in coil and cold rolled steel sheet in coil. The width of thin sheets is 500 to 1500mm; the width of thick sheets is 600 to 3000mm. Thin sheets are classified into ordinary steel, high-quality steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, silicon steel, and industrial pure iron sheets according to the steel type. According to professional applications, there are sheets for oil drums, enamel sheets, bulletproof sheets, etc.
Superiority of Steel Sheet
High wear resistance: The wear-resistant layer thickness of steel sheets is 3 to 12mm, and the hardness of the wear-resistant layer can reach HRC58 to 62. The wear resistance is 15 to 20 times higher than that of ordinary steel sheets, 5 to 10 times higher than that of low-alloy steel sheets, and 2 to 5 times higher than that of high-chromium cast iron, far more wear-resistant than spray welding and thermal spraying.
Better impact resistance: Steel sheets are double-layer metal structures, and the wear-resistant layer and the base material are metallurgically combined with high bonding strength. It can absorb energy during impact, and the wear-resistant layer will not fall off. It is suitable for working conditions with strong vibration and impact, which cannot be compared with cast wear-resistant materials and ceramic materials.
Good temperature resistance: The alloy carbide in steel metal sheet has strong high-temperature stability, and can be used for steel sheets within 500℃. Other special requirements can be customized and produced, and can be used within 1200℃. Wear-resistant materials, such as ceramics, polyurethane, and polymer materials, stick together and cannot meet such high temperature requirements.
Good connectivity: The base material of steel sheets is ordinary Q235 steel sheet, which ensures that the steel sheet has toughness and plasticity, providing strength to resist external forces. It can be connected with other structures through welding, plug welding, bolt connection, etc. The connection is firm and not easy to fall off, and the connection method is more diverse than other materials.
Good selectivity: Steel sheets can be selected with different thickness base materials, overlaid with different thickness and different purpose alloy wear-resistant layers, to obtain steel sheets of different thickness and different purposes, with a thickness of up to 30mm.
Good processing performance: Steel metal sheet can be processed into different specifications and sizes according to needs, can be processed, cold-formed, welded, bent, etc., convenient to use. It can be welded in situ, saving time and effort in maintenance and replacement work, greatly reducing work intensity.
Good cost-effectiveness: The price of steel sheet is higher than that of ordinary materials, but considering the service life of the product, maintenance, spare parts, downtime losses and other costs, its cost-effectiveness is much higher than that of ordinary steel sheets and other materials.
