It has good corrosion resistance, heat resistance, low temperature strength and mechanical properties, good hot workability such as stamping and bending, and no heat treatment hardening phenomenon. Usage: tableware, cabinets, boilers, auto parts, medical equipment, building materials, food industry (use temperature -196°C-700°C).

304 stainless steel strip is the brand name in American stainless steel standards (such as ASTM standards). It is a typical brand of 18-8 Cr-Ni Austrian stainless steel. Due to its excellent comprehensive performance and wide range of uses, its production and sales account for To about 80% of Austrian stainless steel. For 304 and its derivative grades, there are clear regulations in the American Society for Testing and Materials stainless steel grade standard ASTMA959-04 and Japanese JIS, my country GB, international ISO, European EN and other stainless steel standards. However, recently, 304 derivatives that are not included in domestic and foreign standards have appeared in my country's domestic market (such as 304J5, containing only 4.3% nickel), or products with the same name as 304J1 and 304J2 in Japan's JIS but with different ingredients.

Stainless steel grade "304" (S30400) is the grade name in American stainless steel standards (such as ASTM standards). In my country's newly formulated stainless steel grade standard GB/T20878-2007, the corresponding grade is 06Cr19Ni10 (the old grade is 0Cr18Ni9). From the perspective of development prospects, both the production and consumption of ferritic stainless steel will see greater growth in the future. In response to these circumstances, industry insiders believe that the limited development of chromium-manganese stainless steel should be a direction for China, but the 200 series promoted by the domestic industry is not a chromium-manganese steel with a nickel content of about 1% and a very low chromium content, as Foreign experts have analyzed that this type of steel has very poor anti-corrosion properties and cannot be used in most fields. Use of this type of stainless steel in large quantities will inevitably cause great harm to downstream users, so the sale and use of this type of steel should be avoided in the Chinese market. Steel, resolutely oppose and crack down on counterfeiting and shoddy steel. Through publicity and case analysis, users should be aware of this steel and understand the problems of this steel. Producers and sellers should be responsible to users and cannot harm them for temporary benefits. The image and reputation of stainless steel. Regarding the standard issue of chromium-manganese stainless steel, according to the survey, the current standards for the circulation of chromium-manganese series in the market are very irregular. For a period of time, the Chinese market was even circulated according to the standards of a certain country, region or enterprise. Industry insiders believe that , Now the development of 200 series is not without standards, but without standards for production, import and circulation. Everyone in the industry knows that there are American standards internationally. In order to promptly standardize production and market behavior in China, our Stainless Steel Branch organized production companies to draft a technical specification for chromium-manganese stainless steel with reference to American standards at the end of last year and sent it to the Stainless Steel Branch. It is used as a reference among member units. The industry association hopes that on the basis of this specification, the relevant national departments can formulate industry standards or national standards as soon as possible and carry out inspections through standards. The scrap management of chromium-manganese stainless steel has become a top priority. Since 200 series steel is non-magnetic, it is difficult to distinguish it from the 304 grade during scrap recycling. Therefore, from the early use to the classification of scrap steel, a scientific systematic management system must be established to solve the regeneration problem of high manganese, high phosphorus, and copper-containing scrap steel, and to avoid many difficulties caused by scrap steel raw materials in the new round of smelting process. solved problem.
