Delayed fracture is a phenomenon of sudden brittle failure of materials after a certain period of time under the action of static stress. It is a kind of environmental embrittlement caused by the interaction of materials, environment and stress. It is a form of material deterioration caused by hydrogen. Delayed fracture phenomenon is one of the main factors that prevent high strength bolts from increasing their strength.

How to choose the product surface treatment

How to choose the product surface treatment

On the other hand, for threaded fasteners, the coating is also required to be thin enough that the thread can still be spun after plating. Generally, the temperature limit of the coating is lower than that of the fastener material, so it is also necessary to consider the operating temperature requirements of the fastener.
