How much do you know about high strength screws?


Bolts made of high-strength steel, or need to exert a greater pre-tightening force, can be referred to as high-strength screws. High-strength screws and more for bridges, rails, high pressure and ultra-high pressure equipment connection. Brittle fracture.High-strength bolts used in ultra-high voltage equipment, in order to ensure the sealing of the container, need to exert greater prestress.


Several high-strength bolts on the concept 1. According to the provisions of the bolt performance level of 8.8 or more, known as high-strength screws. Now national standards are listed to M39, for large size specifications, especially the length is greater than 10 ~ 15 times the high strength screws, domestic production is still short-term.


Titanium screws and general stainless steel, iron, copper screws are the same, but the material is titanium material, the general titanium material is pure titanium TA2 and titanium alloy TC4 material. Titanium screws more expensive raw materials, made too very beautiful, it seems crafts, titanium acid corrosion, so titanium screws are generally higher prices. Titanium is a highly reactive metal used as a starting material for titanium alloy screws. Compared with traditional stainless steels, titanium screws have better flexibility and oxidation resistance. In a wide range of industries more widely used, ordinary stainless steel screws in high pressure environment compared with titanium screws, titanium screws more compressive strength, so aerospace metal, will choose to produce titanium, titanium screws as a One of the connectors.
