First of all, you can look at the logo, 304 stainless steel usually marks its material on the material or product. Common identifiers are "304", "SUS304", "S30408" and "06Cr19Ni10". These signs are representative of 304 stainless steel. When purchasing, be sure to carefully check the logo on the product to ensure that it matches the real 304 stainless steel.

First of all, from the point of view of corrosion resistance, the difference between 321 stainless steel and 304 stainless steel is not large. Both have excellent corrosion resistance and are able to maintain stable chemical properties in a variety of environments. This makes them ideal for manufacturing a wide range of corrosion-resistant equipment, containers and pipes.

With the development of electric vehicles, higher requirements are put forward for motor performance, and high energy efficiency and high power density are becoming more and more important. The design of the motor core is one of the important factors

Dual-phase stainless steel was smelted by medium frequency induction furnace and cast into round ingot in sand mold. The ingot is forged into a 10mm thick plate, and then hot rolled into a 5mm thickness plate, and the sample of 50mm×50mm is taken on the plate for test. The solution temperature is 1050, 1150 and 1250℃ respectively, and the holding time is 20min.

The implementation standard of S30403 stainless steel is GB/T 24511-2017 "Stainless steel and heat-resistant steel plates and strips for pressure equipment". This standard makes clear the chemical composition of S30403 stainless steel, requiring the phosphorus content to be less than 0.035% and the sulfur content to be less than 0.015%.

Stainless steel surface cleaning, pickling and passivation, in addition to maximizing corrosion resistance, but also to prevent product pollution and obtain aesthetic effects. In the GBl50-1998 "Steel pressure vessel", the surface of the container made of stainless steel and composite steel plate with anti-corrosion requirements should be pickled and passivated.

To address the above problems, researchers such as Takuma Sato of Oita University in Japan developed a thermal measurement based iron loss distribution evaluation system. The system uses a thermal imaging camera to capture the heat distribution of the silicon steel after processing, thus assessing the iron damage contactless.

The main purpose of flatness treatment is to further process and adjust the stainless steel plate through professional leveling equipment. These devices, with their precise control systems and efficient processing mechanisms, enable comprehensive inspection and calibration of the plates. In the flatness treatment process, not only the internal stress can be eliminated, but also the flatness of the plate can be precisely controlled, so that it can achieve higher processing accuracy and quality standards.
