Stainless steel(stainless steel) is an abbreviation for acid resistant stainless steel. Stainless steel is called stainless steel for weak corrosive media such as air, Steam, and water; Chemical corrosion resistant medium(acid, alkali, alkali, salt and other chemical corrosion) steel corrosion is called acid resistant steel.
Because of their different chemical composition, their corrosion resistance is different. Ordinary stainless steel is generally not resistant to chemical medium corrosion, while acid steel is generally antirust. The word "stainless steel" does not simply refer to a kind of stainless steel, but refers to more than one hundred kinds of industrial stainless steel. Each kind of stainless steel developed has good properties in its specific application field. The key to success is to find out the purpose and then determine the correct type of steel. In architectural applications, only six types of steel are usually used. They all contain 17% to 22% chromium, and better steel also contains nickel. The addition of Mo can further improve the corrosion resistance of the atmosphere, especially the corrosion resistance of chlorine atmosphere.
Stainless steel refers to air, steam, water and other weak corrosion media and acid, alkali, salt and other chemical corrosion media corrosion of steel, also known as stainless steel. In practical application, the steel resistant to weak corrosion medium is called stainless steel, and the steel resistant to chemical medium is called acid resistant steel. Because of the different chemical composition, the former is not necessarily resistant to the corrosion of chemical media, while the latter is generally antirust. The corrosion resistance of stainless steel depends on the alloy elements contained in the steel.
Solbright released a research report on China's stainless steel market monitoring and investment prospects from 2018 to 2023. According to statistics, in the first half of 2018, global stainless steel and crude steel output increased by 9.5% year-on-year to 12.767 million tons, and global production increased by 9.5% year-on-year. According to the National Bureau of Statistics, China's stainless steel production in the first half of the year increased by 6.51% year-on-year to 6.525 million tons. Since electrolytic manganese is an indispensable raw material in the production of stainless steel, the growth of global stainless steel production will directly drive the growth of global demand for electrolytic manganese.
It is estimated that global (excluding China) demand for electrolytic manganese will increase by 4.14 to 11.28 tons in 2018 due to the growth of stainless steel.
