What are the surface treatments of 316 stainless steel screws


316 stainless steel screw is a high-grade stainless steel material, which means that it has good performance, and its corrosion resistance is strong in stainless steel material. Today, Shenzhen Heat Hardware Co., screw manufacturers will briefly introduce the common surface treatment methods of stainless steel screws.

Oil cleaning is a common surface treatment method for 316 stainless steel screws, also called natural treatment. During the production process of stainless steel screws, oil stains adhere to the surface, which not only affects the appearance of the surface of stainless steel screws, but also makes stainless steel screws unusable due to the oil stains on the surface. Therefore, most stainless steel screws will be degreasing on the surface. The method of degreasing is also very simple. Pour into the stainless steel special cleaning and degreasing agent at room temperature, and clean it for 3-8 minutes and then dry it. Passivation: In addition to making the surface of stainless steel screws brighter, stainless steel screw passivation can also make stainless steel more ductile and enhance its performance, so that stainless steel screws are not easy to break during use. The passivation treatment is also relatively simple. Soak in passivation solution for 15-30 minutes, wash and dry.


Electroplating is often used in the surface treatment of 316 stainless steel screws. There are many types of surface electroplating, which can be galvanized, nickel-plated, etc. according to customer requirements. Galvanizing of stainless steel screws not only has low processing costs, but also makes stainless steel screws more durable and reliable. Aspect of protection.
