Which to Choose for the Treatment of Fastener Surfaces: Galvanizing, Phosphating, Blackening or Chrome Plating?

2021-10-22T14:53:16+08:00

Keywords:fasteners Almost all commercial fasteners are made of carbon steel and alloy steel and are generally corrosion resistant. Therefore, the coating of the surface treatment must be firmly attached and not shed during installation and dismounting. On the other hand, for threaded fasteners, the coating is required to be thin enough so that the threads can still screw together 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.   The main purpose of surface treatment is aesthetics and corrosion [...]

Yijin Hardware Engineer Explains in Detail the Principle of Selecting Stainless Steel Wires for Fasteners and Several Identification Methods

2021-10-22T14:49:32+08:00

Keywords:fasteners,Yijin hardware engineer explained in detail the selection principle of stainless steel wire for fasteners and several methods of identification Most stainless steel materials can be made into steel wire or bar for fastener production, there are Austenitic stainless steel, ferrite stainless steel, martensitic stainless steel, precipitation hardened stainless steel. About the selection of materials for stainless steel wire fasteners, screw master is like this: fasteners are mechanical basic parts, great demand, usually bolts, screws, rivets and other bolts in order to ensure safety or generally do not consider the influence of temperature in bad environment or other dangerous conditions. Common [...]

Several Common Surface Treatments for Steel Structure Bolts

2021-09-23T15:53:32+08:00

Several common surface treatments for steel structure bolts Electroplating, hot dip galvanizing and mechanical equipment plating on the surface of fasteners are widely used. The whole process of creating a soil layer on the surface of fasteners can show a more beautiful and elegant surface after surface treatment, and the corrosion resistance of fasteners themselves will gradually improve.The key goal is to make the fasteners themselves get corrosion resistance, in order to improve the credibility and adaptability of fasteners application, so the quality of the surface treatment of fasteners to distinguish, the key is to check whether the corrosion resistance of fasteners is [...]

The Most Comprehensive of Screws Fastener Surface Treatment Process

2020-11-04T17:04:39+08:00

For fasteners surface treatment, people generally pay attention to beauty and corrosion, but the main function of fasteners is to tighten parts, and surface treatment has a great impact on fasteners fastening performance, so when choosing the surface treatment, should also consider the fastening performance factor, that is, the installation torque - pretightening force consistency. The surface treated coating must be firmly attached and cannot fall off during installation and removal. For threaded fasteners, the coating must be thin enough to allow the thread to spin after plating.Generally, the temperature limit of the coating is lower than that of the [...]
