1. Carbon (C) Carbon is the most important element affecting the cold plastic deformation of steel. The higher the carbon content, the higher the strength and lower the plasticity of the steel. For ev...

According to the characteristics of the cold heading process, the following requirements are put forward for the mechanical properties of steel:  1) The yield strength Re and deformation resistance sh...

1. Tightening method: Also called the additional tightening method, it is suitable for inspection of important fasteners. The tightening torque of bolt connections in important parts should be inspect...

Bolt performance grades are divided into more than 10 grades, including 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, and 12.9. Bolts of grade 8.8 and above are made of low carbon alloy steel or medium car...
