Скачать или смотреть High Strength Bolt

Bolts made of high-strength steel, or bolts that require a large preload force, can be called high-strength bolts.
1. High-strength bolts are mostly used for the connection of Bridges, rails, high pressure and ultra-high pressure equipment.
2. The breakage of such bolts is mostly brittle fracture. For high-strength bolts used in ultrahigh pressure equipment, in order to ensure the sealing of the container, a large prestress is required.
3. High-strength bolts are capable of bearing loads larger than ordinary bolts of the same specification.
4. The material of ordinary bolts is made of Q235 (i.e. A3). The material of high-strength bolts is 35# steel or other high-quality materials, which are heat treated after being made to improve the strength.
