Stainless Steel U Bolt, also known as riding bolt, is a long and short standard part named after its U-shaped shape. It has threads at both ends that can be connected with nuts. It is mainly used to fix tubular objects such as water pipes or sheet objects such as car leaf springs. Because its way of fixing objects is like a person riding on a horse, it is called riding Stainless Steel U Bolt. Stainless Steel U Bolt is divided into carbon steel Q235, Q345 alloy steel, stainless steel 201, 304, 316, etc., that is, carbon steel and stainless steel.

What are the surface treatment effects of Stainless Steel U Bolt?

1. Blackening and blackening are a common means of heat treatment of Stainless Steel U Bolt. The principle is to produce a layer of oxide film on the surface to isolate the air to achieve the purpose of rust prevention. Blackening treatment can be used when the appearance requirements are not high.

2. Electroplating: Plate gold, silver, copper, tin, nickel, chromium and other metals on the surface as needed, and the appearance will show the metal color of the plated metal. The salt spray test takes more than 24 hours. Electrogalvanizing technology is a traditional metal coating treatment technology, which provides basic corrosion resistance for the surface.

3. Painting: Apply paint (colored paint or Dacromet) on the surface of U as needed, and the appearance is silver, black, and color. The salt spray test is more than 240 hours. The purpose is to obtain good heat resistance, corrosion resistance and friction reduction properties.

4. Phosphating: It is a process of forming a phosphate chemical conversion film by chemical and electrochemical reactions. The phosphate conversion film formed is called a phosphate film. Its purpose is to provide a protective film for Stainless Steel U Bolt, to prevent metal corrosion to a certain extent, and to improve adhesion and corrosion resistance.
