304 stainless steel pipes are still rust-proof after drawing?
Many friends are thinking that can prevent rust after drawing 304 stainless steel pipes? In fact, the anti-rust effect is still there, but compared with the general 304 bright tubes, the performance has indeed decreased. The surface treatment of 304 stainless steel pipes mainly includes bright and matte surfaces. Compared with ordinary shiny stainless steel, the brushed matte wear resistance is more ordinary and looks more upscale, which is very popular among the public. However, after brushing, the corrosion resistance of stainless steel pipe is relatively low. If it is not maintained properly, it is more likely to rust than bright tube .
As corrosion-resistant steel, 304 stainless steel pipes are mainly composed of iron, carbon, nickel, chromium and other elements. Chromium can form a chromium-rich film on the surface of 304 stainless steel pipes. This prevents further oxidation and rust of stainless steel pipes. The chromium-rich protective film on the surface of the stainless steel pipe after drawing is destroyed. The wire drawing process will lose the thickness of stainless steel plate to a certain extent, generally between 0.1 and 0.2mm, and the corrosion resistance of stainless steel pipes will also decrease accordingly, making it easy to cause rust. Since the human body, especially the palms, has relatively strong oil and sweat secretion, stainless steel wire drawing board is often touched with hands and will leave more obvious fingerprints and need to be scrubbed regularly. If you choose a wire-teared stainless steel pipe, you should pay attention to maintenance and clean it well to avoid contact with chemicals. It is best not to use wire-teared stainless steel pipes in coastal areas.
Although 304 stainless steel pipes still have certain anti-corrosion and rust effects after drawing, it is still recommended that friends who have brushed stainless steel pipe products at home remember to take care of them occasionally.
Definition of stainless steel wire drawing and how to purchase stainless steel wire drawing products
1, Stainless steel wire drawing Definition of
Stainless steel wire drawing wire drawing using stainless steel as processing object, and cooperate with wire drawing machine to achieve the artistic effect of wire drawing. According to different drawing processes, the following scribing effect is:
1. Snow pattern, there are many dots on the product appearance, and all dots are arranged according to the rules.
2. Nylon pattern, has different length lines on the appearance of product .
3. Straight silk pattern (straight silk pattern), there are many lines from top to bottom, but it is uninterrupted from top to bottom.
2. How to buy stainless steel wire drawing products
1. Look at the weight of the product
Stainless steel products themselves have Zheng Liang, so when purchasing, they can be compared by weight. Heavier things tend to have better quality. And light stuff may have thin iron sheets welded on the surface, with a short service life.
2. Check the feel
Although the brushed finish stainless steel surface presents different brushed finish lines, it will feel very smooth after touching with your hands, and all the details will be handled well.
3. Observe product performance
brushed finish stainless steel products. Consumers need to determine the parameters based on the use of the product when purchasing. For example, when we choose and buy stainless steel hinges, we must understand the reset of the product and also check the opening angle of the spring. Must be kept right angles for easy opening and closing.
wire drawing process stainless steel is very wonderful in manufacturing process. It is strictly built in accordance with the specifications, and when it is shipped, it also needs to be tested.
