Advantages of Stainless Steel Pickling and Passivation Solution
In the vast majority of cases, stainless steel products require welding operations. However, after welding, stains such as weld spots and high-temperature oxidized skin will remain on the surface of stainless steel. Weld spots on the welded mouth, the color difference is large, no stainless steel...Read more -
Common Metal Polishing Methods
1. Mechanical Polishing Mechanical polishing is to rely on cutting, plastic deformation of the surface of the material to remove the convex part of the polished surface and get a smooth surface polishing method, generally using oil stone strips, wool wheels, sandpaper, etc., mainly hand-operated,...Read more -
The essential difference between passivation rust prevention and electroplating
Over time, rust spots are inevitable on metal products. Due to variations in metal properties, the occurrence of rust varies. Stainless steel is a corrosion-resistant metal with excellent performance. However, in special environments, there is a need to enhance its corro...Read more -
Common scenarios for the use of stainless steel surface treatment agents
In metal machining processes, the surface of stainless steel products is often contaminated with dirt, and regular cleaning agents may struggle to thoroughly clean it. In general, contaminants on the surface of stainless steel can be industrial oil, polishing wax, high-t...Read more -
Corrosion classification of metal materials
Corrosion patterns of metals can generally be divided into two categories: comprehensive corrosion and localized corrosion. And localized corrosion can be divided into: pitting corrosion, crevice corrosion, galvanic coupling corrosion, intergranular corrosion, selective ...Read more -
Can stainless steel sheets still be corrosion-resistant after wire drawing?
After the stainless steel sheet undergoes wire drawing, it still retains some corrosion resistance and rust prevention effects. However, compared to stainless steel sheets that have not undergone wire drawing, the performance may slightly decrease. Cur...Read more -
Comparison of 200 series, 300 series and 400 series stainless steel
Currently in the Chinese market sales of stainless steel is mainly 300 series and 200 series, the difference between the two is the amount of chemical element nickel content, which caused them in the performance and price of the huge difference. At the current level of n...Read more -
Surface pretreatment before metal passivation treatment
The surface condition and cleanliness of the substrate before the metal passivation treatment will directly impact the quality of the passivation layer. The surface of the substrate is generally covered with an oxide layer, adsorption layer, and adhering pollutants such ...Read more -
Copper Antioxidation – Exploring the Mysterious Power of Copper Passivation Solution
In the field of metal processing, copper is a common material widely used due to its excellent conductivity, thermal conductivity, and ductility. However, copper is prone to oxidation in the air, forming a thin oxide film that leads to a decrease in performance. To enhan...Read more -

Formation of Metal Passivation and Thickness of Passivation Film
Passivation is defined as the formation of a very thin protective layer on the surface of a metal material under oxidizing conditions, achieved by strong anodic polarization, to inhibit corrosion. Some metals or alloys develop a simple inhibiting layer at the activation ...Read more -
The difference between phosphating and passivation treatments in metals lies in their purposes and mechanisms.
Phosphating is an essential method for corrosion prevention in metal materials. Its objectives include providing corrosion protection to the base metal, serving as a primer before painting, enhancing the adhesion and corrosion resistance of coating layers, and acting as ...Read more
