Weathering steel plate, as the name implies, has good weather resistance. It is based on ordinary steel plate, by adding a certain proportion of copper, nickel, chromium and other alloy elements, so that a dense oxide film is formed inside the metal, thereby protecting the steel plate. This kind of steel plate not only has high corrosion resistance, but also has good wear resistance, weather resistance and welding performance. The main grades are S235J0WP, S235J2WP, S235J2W, A588grA, CortenA, CortenB, Q355NH, Q235NH, Q345NH, Q355GNH, Q295NH, Q295GNH, Q355GNHL, 09CuPCrNi-A, SPA-H, Corten steel, Cu-P.
A36 is an American standard carbon structural plate, which is subject to ASTM A36/A36M. This standard is applicable to riveting, bolting and welding structures for bridges and buildings, as well as general purpose structural steel quality carbon steel sections, plates and bars.
S235JR is a European standard non alloy structural steel, which is equivalent to the national standard Q235B, that is, carbon structural steel with low carbon content. It is widely used for welding, bolting and riveting structures. It can also be used for building, bridge, ship, vehicle structural parts, manufacturing various tools, cutting tools, molds and measuring tools.
A588 weathering steel plate is a low-alloy high-strength structural steel plate designed to improve atmospheric corrosion resistance. This steel plate can form a dense protective rust layer on the metal surface by adding specific alloy elements such as copper (Cu), chromium (Cr), nickel (Ni), etc. to the steel, thereby significantly improving its atmospheric corrosion resistance. The weather resistance of A588 weathering steel plate is 2 to 8 times that of ordinary carbon steel, with a longer service life and lower maintenance costs.
NM500 steel plate is a high-strength wear-resistant steel plate with high wear resistance.
NM500 wear-resistant steel plate is widely used in engineering machinery, environmental protection machinery, metallurgical machinery, abrasives, bearings and other product parts.
NM360 wear resistance steel plates
GB/T 24186 NM360 abrasion resistant steel plates are high strength steel and allow the weight of structural parts to be significantly reduced. In addition, NM360 steel plates also has advantages of excellent welding performance, good toughness, uniform quality and beautiful appearance, good processing performance, etc.
NM450 wear resistant steel plate
NM450 wear resistant steel plate is a wear-resistant high-end varieties, with good cutting, bending, welding performance. Wear-resistant steel (Abrasion Resistance Steel ) is widely used in engineering, mining, construction and agriculture machinery products under extremely harsh working conditions with the requirement of high strength and high wear resistance, such as bulldozers, loaders, excavators, dump trucks and various mining machinery, etc. Meanwhile, NM450 Wear Resistant Steel Sheets are also used as high strength structural steel with more than 850MPa yield strength.
Mn13 is a high manganese wear-resistant steel plate, high manganese steel Mn13 is the best choice to resist strong impact, high pressure material wear and other wear-resistant materials, with other wear-resistant materials can not be matched by work hardening characteristics, under the action of large impact load or large contact stress, the surface layer of the steel plate produces work hardening, and the surface hardness is rapidly increased from HB200 to more than HB500, thus producing a high wear-resistant surface layer, and the austenite of the inner layer of the steel plate still maintains good impact toughness.
7075 aluminum alloy is an aluminum alloy with zinc as the main alloying element. It has excellent mechanical properties, showing good ductility, high strength, toughness and good fatigue resistance. Due to the presence of microsegregation, it is more brittle than many other aluminum alloys, but has significantly better corrosion resistance than 2000 alloys. It is one of the most commonly used aluminum alloys in high-stress structural applications and has been widely used in aircraft structural components.
