Material Selection For DIN 933 Bolts

　　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.
