Stainless steel protective film is a large number of stainless steel consumables used in the field of stainless steel processing, production and circulation. Generally, stainless steel materials that have undergone surface processing basically need to be protected by stainless steel protective film. Let’s take a look at how to paste stainless steel film. Main points of stainless steel production and processing manufacturers using stainless steel protective film 1. Ordinary stainless steel protective film: only used to protect the stainless steel surface Usually on the most commonly used surfaces, stainless steel frosted surface, stainless steel brushed surface, stainless steel mirror BA surface; usually the frosted brushed surface should be pasted with a stainless steel protective film with a slightly higher viscosity, generally above 70 sticks. The stainless steel mirror panel BA board needs to be pasted with a stainless steel protective film with a lower viscosity, generally below 40, and different viscosity protective films should be pasted according to different materials and the surface finish of the stainless steel plate. 2. Stainless steel protective film (laser film) for laser: usually used for laser cutting of stainless steel plate In general, the stainless steel plate used for stainless steel laser cutting cannot...
1) The content of alloying elements, generally speaking, when the content of chromium is 10.5%, steel is not easy to rust. Chrome Nickel The higher the content, the better the corrosion resistance. For example, the content of nickel in 304 material is 8-10%, and the content of chromium is 18-20%. Such stainless steel will not rust under normal circumstances. 2) The smelting process of the manufacturer will also affect the corrosion resistance of stainless steel. A large stainless steel plant with good smelting technology, advanced equipment and advanced technology can ensure the control of alloying elements, the removal of impurities, and the control of the cooling temperature of the billet, so the product quality is stable and reliable, the internal quality is good, and it is not easy to rust. On the contrary, some small steel mills have backward equipment and backward technology. During the smelting process, impurities cannot be removed, and the products produced will inevitably rust. 3) The external environment, the climate is dry and ventilated, and the environment is not easy to rust. The air humidity is high, continuous rainy weather, or environmental areas with high pH in the air are prone to rust. 304 stainless...
With the improvement of people’s living standards, 304 stainless steel is being used more and more widely, and there are more and more manufacturers of 304 stainless steel. Of course, there will inevitably be mixed with bad quality, which is very important to customers. It is said that how to choose has become a big headache. 304 stainless steel has a smooth surface, high plasticity, toughness and mechanical strength, and is resistant to corrosion by acid, alkaline gas, solution and other media. It is an alloy steel that does not rust easily, but not rust-free. 304 stainless steel plate refers to a steel plate that is resistant to corrosion by weak media such as atmosphere, steam and water, while acid-resistant steel plate refers to a steel plate that is resistant to chemical corrosive media such as acid, alkali, and salt. The following 304 stainless steel plate manufacturers will teach you how to distinguish the quality of stainless steel plates? 1. There should be no scratches on the surface of the stainless steel plate. This is a more critical point that directly affects the quality of the stainless steel mirror panel. If there are scratches on the stainless steel raw material...
The maximum carbon content of 316 stainless steel pipe is 0.03, which can be used in applications where annealing after welding cannot be performed and maximum corrosion resistance is required. 316 and 317 stainless steel (see below for the properties of 317 stainless steel) are molybdenum-containing stainless steels. The overall performance of this steel is better than that of 310 and 304 stainless steel. Under high temperature conditions, when the concentration of sulfuric acid is lower than 15% and higher than 85%, 316 stainless steel has a wide range of uses. 316 stainless steel also has good performance against chloride erosion, so it is usually used in marine environments. 316 stainless steel, also known as 00Cr17Ni14Mo2 corrosion resistance: The corrosion resistance is better than 304 stainless steel, and it has good corrosion resistance in the production process of pulp and paper. And 316 stainless steel is also resistant to erosion by marine and aggressive industrial atmospheres. Heat resistance In intermittent use below 1600 degrees and continuous use below 1700 degrees, 316 stainless steel has good oxidation resistance. In the range of 800-1575 degrees, it is best not to use 316 stainless steel continuously, but when 316 stainless steel is used...
