2022-06-10
Fishbolt is a product widely used in heavy industry.It is very convenient to use and the price is relatively low.The Arema Standard Fish Plates is mainly used in the splint connection of the rail joint,which plays a fixed role and can sometimes replace the hexagonal bolt.Fish bolt is mainly used in metallurgical industry,coking industry,iron and steel industry in the track laying,rail and rail joint connection fastening.High strength Fish Plates can be made from low carbon alloy steel or medium carbon steel with heat treatment,and the rest are ordinary Fish Plates. 
Bolts made of high strength steel or requiring a large preload can be called high strength Fish Plates.High strength Fish Plate is used for bridge,rail connection,the fracture of this bolt is brittle fracture.High Strength Bolts used in ultra-high pressure equipment need to be prestressed to ensure the sealing of containers.The high strength Fish Plate is able to bear more load than the ordinary bolt of the same specification. From the material comparison,the high strength Fish Plate is made of high strength material.The screw,nut and washer of high strength bolt are made of high strength steel,commonly used 45 steel,40 boron steel,20 manganese titanium boron steel and so on.Ordinary bolts are usually made of Q235 steel. From the strength grade comparison,high strength Fish Plate is widely used,commonly used 8.8 and 10.9 two strength grade,of which 10.9 is the majority.Ordinary Multi Standard Fish Plate strength grade is much lower,generally 4.8 and 6.8.
