The selection of DIN 933 bolts is mainly considered from the following five aspects.
1. Requirements for DIN 933 bolt material in terms of mechanical properties, especially strength;
2. The requirements of working conditions on the corrosion resistance of the material;
3. The requirements of the working temperature on heat resistance (high-temperature strength, oxidation resistance) of the material;
4. The requirements of DIN 933 bolt production technology on material processing performance;
5, Other aspects, such as weight, price, procurement factors must be considered.
