Steel plate is a plate of steel poured with molten steel and pressed after cooling. It is flat, rectangular and can be rolled directly or sheared from a wide strip of steel. According to the thickness of steel plate, thin steel plate <4 mm (the thinest 0.2 mm), medium thickness steel plate 4~60 mm, extra thickness steel plate 60~115 mm steel plate according to the rolling points, hot rolling and cold rolling. The width of the sheet is 500~1500 mm; The thick width is 600~3000 mm. The sheet is divided 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 sheet, etc. According to the professional use, there are oil drums with board, enamel board, bulletproof board, etc.; According to the surface coating, there are galvanized sheet, tin sheet, lead sheet, plastic composite steel plate.
Resistant Steel Plate: Wear Resistant Steel Plate refers to a special Plate product designed for use under large area Wear conditions. The commonly used wear-resistant steel plate is in the toughness, plasticity of ordinary low carbon steel or low alloy steel surface by surfacing method composite a certain thickness of high hardness, good wear resistance of the alloy wear-resistant layer made of plate products. In addition, there are cast wear – resistant steel plate and alloy hardened wear – resistant steel plate.
Structural features of wear-resisting steel plate: Wear-resisting steel plate is composed of two parts: low carbon steel plate and alloy wear-resisting layer. The alloy wear-resisting layer is generally 1/3~1/2 of the total thickness. When working, the matrix provides comprehensive properties such as strength, toughness and plasticity to resist external forces, and the alloy wear layer provides the wear resistance to meet the requirements of specified working conditions.
Wear-resisting steel plate alloy wear-resisting layer and substrate are metallurgical combination. Through special equipment, the use of automatic welding process, the high hardness self-protection alloy welding wire evenly welded on the substrate, the number of composite layers of one layer to two layers or even multiple layers, the composite process due to the alloy shrinkage ratio is different, uniform transverse crack
