product description:

        In the process of smelting, processing and use of stainless steel materials, corrosion often occurs. In order to improve the corrosion resistance of stainless steel materials, pickling, passivation and other methods are often used in the production and processing of stainless steel to treat the surface of stainless steel materials. At present, the pickling passivation process used by most manufacturers cannot meet the requirements of pickling and passivation of many grades of stainless steel materials, so it cannot achieve the purpose of metal surface treatment. It is specially used for cleaning stainless steel materials with surface defects to prevent rust. Its unique characteristics are widely applicable, suitable for stainless steel materials of various grades and metallographic structures (300 and above series materials). Economical and practical features.

        Stainless steel welding spot pickling paste is a paste-like acid chemical agent. The use of this agent can replace the traditional pickling soaking and mechanical grinding and polishing processes, and can quickly, easily and accurately remove the black welding spots formed by stainless steel welding. (Oxide film), restore the primary color and luster of stainless steel, greatly reduce labor intensity and improve production efficiency.

The main purpose:

        It can remove the yellow, blue and black welding spots produced by argon arc welding of stainless steel and maintain the true color of stainless steel; other products will easily cause the surface of stainless steel to turn white after removing the welding spots. This product overcomes this shortcoming. (Similar products are all whitish)

Scope of application:

        This product is widely used in stainless steel decoration industry, kitchen utensils, chemical machinery, food machinery, dyeing and finishing machinery and other stainless steel products industries.


        Apply this product on the welding spot with a stainless steel or plastic brush, keep it for 15-20 minutes, wipe it off with a rag, rinse it with clean water, and it will be as smooth as new. After treatment, the stainless steel will keep its natural color.

Use and attention:

        1. After this product is stored for a period of time, clear liquid will be precipitated on the upper part (to protect the colloid in the lower layer), and it should be fully stirred before use.

        2. Apply the agent to the welding spot with a brush, polish it with cotton yarn, etc. later, and then rinse it with clean water.
