Featurers of high strength hot dip galvanized bolts
High strength hot dip galvanized bolt is a typical anodic coating, which is mainly used to improve the corrosion resistance of the substrate. Because of its thin coating thickness, it is mainly used for surface anti-corrosion protection under general environmental conditions.
After chromate passivation treatment, the corrosion resistance of high-strength hot-dip galvanized bolt is greatly improved. The excellent high-strength hot-dip galvanized bolt and hot-dip galvanized screw layer can be used for the outdoor protection of neutral strike, but the corrosion resistance is relatively poor in the harsh industrial atmosphere and coastal climate.
Featurers of high strength hot dip galvanized bolts
The surface treatment method and technology of high-strength hot-dip galvanized bolt and screw have the advantages of low cost, stable and reliable technology and convenient use. However, hydrogen embrittlement is very easy to occur, so the high-strength hot-dip galvanized bolts and screws should be dehydrogenated in time. In addition, it has poor acid and alkali resistance, short anticorrosion time and low environmental protection.
