ANSI B18.2.1 Bolt Corrosion Prevention Method

ANSI B18.2.1 bolts are the most common components in mechanical equipment, and their function is also very important, but ANSI B18.2.1 bolts are the most common type of damage during use, in order to prevent ANSI B18.2.1 Corrosion occurs during the use of bolts. Many manufacturers will finish the surface treatment of ANSI B18.2.1 bolts. Which surface treatment methods can improve the corrosion prevention of ANSI B18.2.1 bolts?

There are four main surface treatments to prevent corrosion of ANSI B18.2.1 bolts:

First, the standard parts are electroplated. This method is to put the standard parts into the metal solution, and then pass the current to cover the surface of the standard parts with a layer of metal. There are many effects on this layer of metal. For example, we can use some different The role of choosing a number of different coating metals, if we want to prevent the standard parts from rusting, then we can plate zinc on the surface of the standard parts.

Second, for the heat treatment of the surface of the standard parts, there are some standard parts. For example, the drill-end screws require a relatively hard surface layer, so the heat treatment can be performed on the self-drilling screws to ensure that the self-drilling screws have sufficient hardness. This is the reason for the heat treatment.

Third, the mechanical plating of the standard parts is to let the metal particles cold-weld the standard parts to ensure some functions of the surface of the standard parts. Mechanical plating and electroplating are basically similar, except that the method we use is different, and the result can be said to be the same.

Fourth, for the surface passivation of standard parts, passivation has two main functions, one function is to strengthen the hardness of the standard parts, and the other is to enable the oxidation of the standard parts to be greatly reduced.

When performing the ANSI B18.2.1 bolt surface treatment process, we can choose the most suitable method based on the specific needs. In this way, ANSI B18.2.1 bolts can only play a better role during use.
