Many people would think that 304 stainless steel pipes used for burglar proof windows stair handrails will rust. This is actually wrong. Although it is said to be 304 stainless steel pipe, it will still rust. Stainless steel products are more difficult to produce. Compared with other metal products, rusty, but due to improper use, how should we deal with stainless steel products.

First of all, we can rinse with water wipe with rags, we can ask someone to process stainless steel ask us to provide rust remover rust remover.

In daily life, pure chloride ion can cause 304 stainless steel pipe to rust. The presence of chloride ions is more common. Common seawater, salt, sea breeze, soil, sweat, etc. all contain chloride ions. Chloride ions will rust intensively, in order to prevent rust, it is necessary to wipe the pipeline frequently to keep it clean dry.

There is also a 304 stainless steel tube. If there is no stainless steel tube integrated into the matrix, the alloy content in the matrix will be reduced the corrosion resistance will be poor. Adding titanium niobium to 304 stainless steel tube stabilizing it will reduce grain boundary corrosion, air corrosion chemical corrosion. The high alloy steel in the medium has beautiful surface good corrosion resistance. Stainless steel contains chromium, which can form chromium film on the surface prevent oxygen corrosion.

304 stainless steel pipe is a general stainless steel material, its corrosion resistance is better than 200 series stainless steel material, its high temperature resistance is also better. Generally, the temperature limit is below 650 ℃. 304 stainless steel has excellent corrosion resistance equivalent intergranular corrosion resistance. For oxidizing acid, it is found that 304 stainless steel has strong corrosion resistance in nitric acid, its concentration is less than equal to 65% lower than boiling temperature. It is resistant to alkali solution, most organic inorganic acids also have good corrosion resistance.

Manufacturing specification of stainless steel pipe.

Stainless steel seamless tube, precision stainless steel tube (capillary 1-6mm), stainless steel welded pipe.

Stainless steel seamless steel pipe plant outer diameter: φ 2mm-1500mm, wall thickness: 0.1-30mm.

Materials: 301, 304, 304L, 316L, 321 (1Cr18Ni9Ti), 310S (0Cr25Ni20), 309S.

Features: high temperature resistance (1150 degrees), chemical pipeline, liquid (gas) transmission pipeline.

Nowadays, many people use stainless steel tubes at home, but there is no difference between Qin Chu's 304 stainless steel tubes other steel plates. Let's talk about four kinds of quality of 304 stainless steel pipe.

First, dry grinding wire drawing.

Filament staple are common in the market. After this surface treatment, 316 stainless steel pipe series stainless steel shows good decorative effect, which can meet the requirements of general decorative materials. In general, 304 series stainless steel can be used. A good result can be obtained by one scrubbing.

Due to the wide range of processing costs, this processing technology has become a low-cost, low-cost process. The center needs equipment, so most processing centers can provide long short wire matte board, of which 304 steel accounts for more than 80%.

2、 Oil mill.

304 series stainless steel shows decorative effect after grinding. Widely used in elevator, home appliances other decorative panels. After one pass grinding, the cold rolling 304 series stainless steel can usually achieve good results. There are still some on the market. The machining center can provide oil-based grinding process of hot-rolled stainless steel, its effect is comparable to that of cold-rolled oil mill.

Oil drawing is also divided into filament staple. The elevator decoration usually uses filament, can use various types of small appliances, Kitchenware other styles.

3、 8 K treatment.

In 8K processing, 304 series stainless steel is obviously better than 200 series stainless steel. 2B cold rolled surface was ground with 8K. Usually, after a round of processing can achieve the mirror effect. At present, the 8K grinding process of nitric acid iron oxide red is cheap, the cost of valuable equipment itself is low. Therefore, the overall grinding cost is low has been widely promoted.

Fourth, titanium.

The choice of decorative materials has gorgeous effect. 304 series stainless steel has been used for titanium decoration for a long time. It is widely used in elevator building decoration materials.
