The basic principles of bolt material selection include:
1, the chemical composition of the material in line with GB / T 3098.1 in the provisions of the fasteners of the performance level of steel chemical composition limit requirements.
2, give full consideration to the processing performance of the material, according to the different processing methods to choose the cold upsetting performance of good materials or easy-to-cut materials.
3, high-strength bolts need to take into account the metallurgical quality of the material, including oxygen content, inclusions and banding organization, to ensure that the fine grain uniformity of the original organization.
4, high-strength bolts also need to ensure the performance of the material heat treatment production process. Including hardenability, hardenability, deformation, decarburization tendency.
5, with production economics, in order to ensure that the performance requirements under the premise of comprehensive consideration of material prices, procurement difficulties, processing costs.
