The performance requirements of antibacterial stainless steel plates are different, and several categories are gradually formed in the process of use. It can be divided into martensitic antibacterial stainless steel plate, ferritic antibacterial stainless steel plate, austenitic antibacterial stainless steel plate, duplex antibacterial stainless steel plate, etc. Antibacterial stainless steel plate is a kind of metal material that has beautiful surface and good corrosion resistance, does not need to undergo surface treatment such as color plating, and exerts the inherent surface properties of antibacterial stainless steel, and is often used in life; Among them, 304 antibacterial stainless steel is mainly used for corrosion-resistant containers, tableware, and medical equipment. 316 antibacterial stainless steel is mainly used in the food industry, watch accessories, pharmaceutical industry and surgical equipment. The antibacterial stainless steel plate has a smooth surface, has relatively high plasticity, toughness and mechanical design strength, and is resistant to acid, alkali gas, solution and other media corrosion. It’s an alloy steel that doesn’t rust easily, but it’s also not stainless steel. Antibacterial stainless steel fingerprint-free identification plate refers to coating a layer of transparent colorless to light yellow liquid protective layer on the surface of antibacterial stainless steel. The textured antibacterial...
What are the keywords commonly used in mechanical polishing? Abrasive: The particles in the polishing wax that play a role in cutting and leveling. Grease: stearic acid, fatty acid, paraffin, etc., which play a role in lubricating and cooling in polishing wax. Cutting force: The ability of the polishing wax to grind and level the workpiece being polished. 2. The general mechanical polishing process is divided into several steps? Answer: The general mechanical polishing process is divided into three steps: rough grinding, medium grinding and fine grinding. Coarse grinding: mainly use sand abrasives to grind workpieces with relatively rough surfaces to remove macroscopic uneven surfaces. Intermediate grinding: On the basis of rough grinding, further polishing is performed to remove rough grinding scratches. After this process, the surface of the workpiece is gradually smooth and bright. Fine grinding: fine polishing process to achieve the desired brightness. Shengding reminds: To get the best performance, you must choose a suitable polishing wax. Our polishing wax comes in a square shape and is easy to use. Use different colors to mark different varieties of polishing wax to avoid confusion. A high content of abrasive can speed up the entire polishing process. This process smoothes...
The surface quality of 304 stainless steel plate is mainly determined by the pickling process after heat treatment. If the surface oxide scale formed by the previous heat treatment process is thick or the structure is uneven, pickling cannot improve the surface finish and uniformity. Therefore, full attention should be paid to the heating of heat treatment or the surface cleaning before heat treatment. If the thickness of the oxide scale on the surface of the stainless steel plate is not uniform, the surface finish of the base metal under the thick part and the thin part will also be different. Therefore, the surface of the steel plate is not uniform. Therefore, it is necessary to uniformly form oxide scales during heat treatment. To meet this requirement, the following issues must be noted: If the stainless steel plate has oil attached to the surface of the workpiece during heating, the thickness and composition of the oxide scale at the oil-attached part will be different from the thickness and composition of the oxide scale in other parts, and carburization will occur. The carburized part of the base metal under the oxide scale will be severely attacked by the acid. The oil...
In the category of stainless steel pipes and fittings, there are many types of stainless steel pipes, including 201, 301, 304, 316, 316L, 2205, and 904L… and other stainless steel pipes. Pipes of different materials have different corrosion resistance. What is the difference between 904L duplex stainless steel and austenitic stainless steel? Many people expressed their curiosity. In response to this problem, the editor of Jude has compiled some relevant materials for everyone to improve: Let’s talk about the advantages of 904L duplex stainless steel pipe: 1. The yield strength is more than double that of ordinary austenitic stainless steel, and it has sufficient plasticity and toughness for forming requirements. The wall thickness of storage tanks or pressure vessels made of duplex stainless steel is 30-50% lower than that of commonly used austenite, which is conducive to reducing costs. 2. It has excellent resistance to stress corrosion cracking. Even the duplex stainless steel with the lowest alloy content has a higher resistance to stress corrosion cracking than austenitic stainless steel, especially in an environment containing chloride ions. Stress corrosion is a prominent problem that is difficult for ordinary austenitic stainless steels to deal with. 3. The corrosion resistance of the...
