After the production of stainless steel (stainless acid-resistant steel) screws is completed, the general treatment method is to remove the oil with a degreasing agent first, and then use a polishing agent for light treatment (chǔ lǐ), after drying, Packed and shipped. Only the screws for oil removal and light treatment can usually be tested for salt spray for 48-72 hours. However, in daily work, customers often consult us for ways to increase the salt spray test time of stainless steel (stainless acid-resistant steel) screws. Because of the large number of foreign customers, due to the environmental impact of shipping on products, to ensure the quality of products delivered, the salt spray test must reach more than 150 hours.
To achieve this goal, we have to passivate the stainless steel (stainless acid-resistant steel) screws (chǔ lǐ). Electrical screws are "quantity products" and are not hand-made artworks. In mass production, they are aimed at achieving high-precision, stable quality and consumer prices. The principle of passivation treatment (chǔ lǐ) is that the surface of stainless steel (stainless acid-resistant steel) undergoes a microchemical reaction on the surface of the stainless steel after it is soaked with a passivating solution, converting the previously chemically active metal surface into a chemically inert metal. Surface, it is difficult to regenerate chemical reactions with external substances. So as to achieve long-term rust effect.
After the passivation of the 304 stainless steel (stainless acid-resistant steel) screw, the minimum concentration of the salt fog (5%-15%) can exceed 150 hours. Non-standard screws utilize the physics and mathematics of the object's bevel circular rotation and friction, and progressively fasten the tool's tools. Screws are a common term for fasteners, spoken daily. The passivation of stainless steel (stainless acid-resistant steel) is essentially a pickling process (chǔ lǐ). Cleaning after passivation is critical and very important. Stainless steel is most susceptible to rust when it encounters acid, so if it is cleaned after passivation (generally With ultrasonic waves (a sound wave with a frequency higher than 20,000 Hz), the salt spray will not erode the stainless steel much, and it is estimated that it can exceed 150 hours.
As a manufacturer specializing in manufacturing stainless steel (stainless acid-resistant steel) screws, screws can be used to perform different surface treatments on stainless steel (stainless acid-resistant steel) screws to meet the customer's assembly requirements. Electrical screw precision is usually 6g (2nd grade, U.S. specification "IFI" is 2A teeth), crude screw used in construction projects is 8g (3rd grade, "IFI" is 1A teeth). The value of screws is very important. There are examples in the world of bankruptcies caused by poor screw quality. There are also examples of aircraft falling down and vehicles being subverted due to poor screws.
