430 stainless steel sheets products

430 stainless steel sheets refers to the resistance of air, steam, water and other corrosive medium and weak acid, alkali, salt and other chemical etching medium corrosion of 430 stainless steel sheets , also known as stainless acid resisting steel. In practical application, often weak corrosion resistant steel known as stainless steel, the corrosion of steel called acid resistant steel. Because of the stainless steel factory  in the chemical composition, the former not resistant to chemical corrosion, while the latter generally has not rust. Alloy elements in stainless steel corrosion resistance depends on the contained in. 430 stainless steel sheets often organized by the state is divided into: martensitic steel, ferritic steel, stainless steel sheets  steel etc.. In addition, according to the component as the chromium stainless steel, chrome nickel stainless steel and chromium manganese nitrogen stainless steel etc.

Low yield stainless steel sheets

12 to 30% chromium , 6 to 12% of nickel and small amounts of other elements. The carbon content of the steel is very low, at room temperature was added austenitic or ferritic organization . It has better corrosion resistance than chromium qiyi 430 stainless steel sheet , weldability and formability . The earliest chrome-nickel stainless steel made ​​in 1912 by the German E. B. Strauss and Mao Demirel . The most commonly used modern 18% chromium , 8% nickel, 18-8 stainless steel. This low yield strength steel , not heat strengthened . But working to strengthen the tendency of large , high-intensity obtained by cold wire and strip . Commonly used steel as 0Cr18Ni9, 0Cr17Ni13Mo2 , etc. , used for the production of chemical containers, equipment lining , pipelines , medical devices and instrumentation. Adding copper and molybdenum qiyi stainless steel 304 sheet , such as 0Cr18Ni18Mo2Cu2Ti better corrosion resistance in sulfuric acid, phosphoric acid, non-oxidizing medium.

Stainless steel sheets industry

After entering the 1990s, China's steel industry has entered a rapid development period, steel demand growth is much higher than the global level. Since 1990, global apparent consumption of qiyi stainless steel sheets with an average annual growth rate of 6%, while the 10-year period in the 1990s, the apparent consumption of stainless steel is 2.9 times the world average annual growth rate. In the 21st century, the rapid growth of China's steel industry.
According to "China's steel industry, Strategic Planning Market Outlook and Investment Analysis Report Preview" statistics, 2000 to 2006, China's steel consumption average annual growth rate of more than 21.17%. Which, in 2001, the apparent consumption of stainless steel reached 2.05 million tons, more than the United States as the world's first stainless steel consumer. In 2008, China's apparent consumption of steel reached 6.24 million tons, down 5.17 percent.
November 2011, China's steel production increased by 11.1% to 12.5 million tons. Production of stainless steel products 336,800 tons, qiyi 430 stainless steel sheet of 65.25%. Guangdong Province, which is the main production base of stainless steel products, the output reached 1.837 million tons, an increase of 41.76%, accounting for 78.62 percent of national output.
