High manganese steel grate plate
production Description
High manganese steel grate plate is a kind of high strength steel, is mainly used to withstand impact, extrusion, material wear and other harsh working conditions.
High manganese steel, also known as Hadfield steel, its chemical composition includes high manganese (10%-15%) and high carbon (0.90%-1.50%) , usually carbon content of more than 1.0%. This kind of steel, because of its strong toughness, in the resistance to severe impact load performance, safety, reliability, can not be compared with other materials. high manganese steel under severe impact or contact stress, the surface will quickly harden, and the core to maintain extremely strong toughness, the external hard internal tough characteristics of both wear and impact resistance, is extremely advantageous. After the surface is worn, the secondary surface is hardened, , so this performance advantage is widely used in mining, metallurgy, military industry, building materials, railway, electric power and other important environment.
High manganese steel grate plate is widely used in , including but not limited to quarrying, mining, mining, coal industry, its unique anti-wear mechanism and excellent physical properties make it an ideal choice in these fields. In addition, with the progress of modern technology, the potential of high manganese steel has been continuously explored. has been applied in such fields as "maglev train", "rock drilling robot", "new main battle tank" and so on, shows its excellent performance and wide application prospects.
Features
The advantages of high manganese steel grate plate are mainly reflected in its wear resistance and work hardening index.
wear resistance: high manganese steel crusher hammer head has good wear resistance, its good toughness, good technology, low price. Under the action of greater impact or contact stress, the surface layer will rapidly produce work hardening, the work hardening index is 5 to 7 times higher than other materials, wear resistance is greatly improved .
work hardening: the main characteristic of the hammer head of high manganese steel crusher is that can not make the surface quickly produce work hardening when the physical impact force is not enough or the contact stress is small, so as to play not its due wear resistance. Therefore, should be selected according to the actual parameters of the equipment before use, if necessary, the equipment can be reformed, to make it play economic benefit.
These advantages make high manganese steel grate plate widely used in quarrying, mining, mining, coal industry and other fields, has become an indispensable wear-resistant steel in heavy industry
