──Jul 22 , 2022What are the differences between 304 stainless steel plates and food-grade stainless steel
Food-grade stainless steel refers to the parts of food machinery that come into contact with food and must meet certain food safety requirements.304304Do you know the difference between stainless steel plates and food-grade stainless steel? Here is an introduction:
Edible stainless steel and304304What is the main difference between stainless steel plates?
Food grade304The production standard of stainless steel is in accordance with that of the United StatesASTMIt is made in accordance with the standards.304304The most important element in stainless steel plates isNiandCrHowever, it is not limited to these two elements. The specific requirements are stipulated by the product standards. The common judgment in the industry is that as long asNiThe content of elements is greater than8%,CrThe content of the element is greater than18%Then it can be determined that the steel is304The output of stainless steel and crude steel has increased8020Ten thousand tons6In the month, the average daily output of crude steel across the country1The output of crude steel continued to rise, increasing by 10,000 tons compared with the previous period. With relatively high profits in the steel industry, the production enthusiasm of steel mills will remain at a high level in the second half of the year. In the first half of this year, China's economy was stable and improving, with the gross domestic product growing year-on-year.
Stainless steel refers to steel that is resistant to weak corrosive media such as air, steam and water, as well as chemical corrosive media such as acids, alkalis and salts. The corrosion resistance of stainless steel depends on the alloying elements contained in the steel.
304The main alloying elements of stainless steel plates areCr(Chromium), so when the chromium element in stainless steel reaches a certain value, the steel will have corrosion resistance. Therefore, the minimum proportion of chromium element in stainless steel is required10.5%Stainless steel also containsNi,TiIn today's society, stainless steel products generally need to undergo polishing treatment during the production process. Only a few products such as water heaters and inner tanks of water dispensers do not require polishing. Therefore, this demands that the raw materials have good polishing performance.
