U-Bolt is widely used, mainly used: construction and installation, mechanical parts connection, vehicles, ships, Bridges, tunnels and railways.
Always used in truck, it is used to stabilize the chassis and frame of the car. For example, leaf springs are connected by U-bolts.
Details:
1. Material properties, density, bending strength, impact toughness, compressive strength, elastic modulus, tensile strength, temperature resistance and color are determined according to the use environment.
2. The commonly used materials are carbon steel Q235A Q345B alloy steel stainless steel, etc. The stainless steel material has 201 304, 321, 304L, 316, 316L.
3. National standard of U-bolt: JB/ZQ4321-2006.
4. The material
U bolts are divided into carbon steel Q235, Q345 alloy steel, stainless steel 201, 304, 316 and so on.
