Non-standard Stainless steel hex socket Screws & bolts by CNC lathe for industrial equipment
Anti-corrosion
Stainless steel screw is made by metal and metal corrosion method mainly has four aspects, namely the nature of the material itself, the use of environment, data and environment of the interface, and improve the design of metal structures, if manufactured complete corrosion resistant alloy to stainless steel screws, unless there are special requirements, otherwise the economic perspective is not practical, or will screw the appearance of corrosion environment factor is the complete isolation, also does not work in practice, can be very difficult.The improvement of metal structure design can improve the influence of special circumstances in a certain situation, but most of the stainless steel screw design can not be fully corrected, and its maintenance function is not permanent, so this method can not be basic treatment, as long as the corrosion prevention on the interface, that is, the surface corrosion prevention treatment is the most widely used method.
Stainless steel screw appearance corrosion prevention disposal refers to the use of various methods in the metal appearance of the maintenance layer, its role is to metal and corrosive environment isolation, in order to inhibit the generation of corrosion process, or reduce the corrosive medium and metal appearance contact, and to avoid or reduce the purpose of corrosion.
The maintenance layer shall meet the following requirements:
1, corrosion resistance, wear resistance, high hardness,
2, tightly structured, intact, small pores.
3, Strong separation from the base metal and good adhesion.
4, Average dispersion with a certain thickness.
The maintenance layer is usually divided into metal coating and non-metal coating two categories, metal coating refers to the corrosion resistance of the metal or alloy in the corrosion prone metal surface to form a maintenance layer, this coating is also known as the coating.There are many ways to produce metal coatings, among which electroplating is the most common method, followed by molten metal dip plating (hot dip plating) and chemical surface treatment.Non-metallic coating refers to the use of organic polymer materials such as paint, and inorganic materials such as ceramics, in the appearance of metal equipment or parts to form a maintenance layer, the maintenance layer can be the matrix metal and environmental media complete isolation, avoid the matrix metal due to contact corrosion in the stainless steel standard parts of the medium and the formation of corrosion
