When choosing food-grade stainless steel, we must first clarify a concept: Food-grade stainless steel refers to stainless steel materials that comply with national standards and certifications. When it comes into contact with food, it can ensure that no substances harmful to human health are produced. Although both 410 and 430 stainless steel materials are widely used in the manufacture of various stainless steel products, whether they are suitable as food-grade stainless steel requires more in-depth discussion. For 410 stainless steel, it belongs to the category of martensitic stainless steel. Its advantage lies in its high chromium content, which makes it highly resistant to corrosion. But at the same time, it also contains a certain amount of iron, which leads to a problem: under certain environmental conditions, it may undergo an oxidation reaction to produce iron ions. These iron ions may dissolve into food, causing potential effects on human health. In addition, 410 stainless steel has relatively poor toughness and is prone to rust, so it is not suitable as food-grade stainless steel in many aspects. ...
BA stainless steel pipe, also known as stainless steel clean pipe, bright annealed pipe or welded pipe (seamless pipe), is a special type of stainless steel pipe. Its inner surface is very smooth, but it is not achieved through polishing technology, but through a specific manufacturing process. This smooth surface has a certain finish, making the inside of the pipe very neat. In addition, BA stainless steel pipes are weldable. BA stainless steel pipes are usually made of high-quality materials such as 304 precision stainless steel pipes or 316L materials, and are mainly used to transport special gases and fluid media. Because its internal surface is smooth, it is not easy for particles in the medium to stay and accumulate. It is especially suitable for use in clean workshops, biopharmaceuticals, clean laboratories, high-purity gases, and liquid crystal displays. In these environments with high purity requirements, BA stainless steel pipes show their unique advantages.

Stainless steel coil plates should be understood. There are many types of cold rolled plates, which can be classified according to shape and size or according to processing technology. For example, the difference between C-shaped roof purlins and Z-shaped roof purlins depends mainly on the focus. Generally, C-type products are 90 degrees, while Z-type products cannot achieve such a focus, only about 60 to 75 degrees. Therefore, steel purlins are used differently with different inclinations. In terms of function, the structural mechanical effects of the strong axis and the weak axis of the cold-drawn C-type roof purlin are quite different, so their structural mechanical effects must also be different. Therefore, during the processing process, there are strict regulations on the standards and material selection of cold-rolled plates. Steel frame structures with different cross-sections have different bearing capacities to support and adapt to different working conditions. Because of this purposeful application advantage, there are different products and great functional advantages in application. At the same time, we must talk about the strength index of cold-rolled steel sheets, which is the ability of the material to withstand the pressure of hard objects on the surface. According to different test methods and application...
Word of mouth is the sense of satisfaction and honor gained by customers in the process, which forms a gradually increasing word-of-mouth publicity effect to the outside world. Customer satisfaction is not only satisfied with the results, but also more picky about the process. Only when customers’ needs are met will they voluntarily spread word of mouth. The above is a brief introduction about “steel strips for stainless steel pipes”. Due to the gaps in the equipment and component structures or the presence of metal or non-metallic deposits on the surface of stainless steel pipes, gaps are formed between the deposits and the surface of the stainless steel pipes, which act as corrosive media. Under this condition, point-like and spherical damage will occur preferentially at the crevices, which is crevice corrosion. In water media containing Cl- and other water media, the partial passivation film is caused by acidification and lack of oxygen in the media solution in the gap. The fundamental way to eliminate gaps is to avoid gaps in structural design. The gaps between the heat exchange equipment tubes and the tube sheets should be cleaned regularly and exposed to seawater and other environments to prevent dirt from accumulating...
