People who use common metals know that hydrogen embrittlement is a great harm to metal nuts. For example, it is easy to cause brittle fracture. If it is not expected beforehand, it will cause serious accidents. Therefore, the hydrogen embrittlement of the nut is to be removed and removed. The hydrogen embrittlement process of the nut is the drying process. What should be noted during the drying process of the nut?
1, should not be used to temper the temperature of the parts;
2. The drying process should be carried out after electroplating (preferably within 1 h), immediately before chromate passivation;
3, drying temperature is 200-230 °C is reasonable, generally lower drying temperature and longer drying time;
4, the drying duration is selected within 2-24h, generally 8h drying duration.
