Duplex stainless steel is a kind of steel with prominent characteristics such as stress corrosion resistance, corrosion resistance, crack resistance and corrosion resistance. It is used in oil refining, chemical fertilizer, chemical, paper, salt industry and other industries, such as atmospheric and vacuum equipment, catalytic cracking and hydrocracking unit, tiers and heat exchangers, continuous sulphuric acid cooking or intermittent cooking. The device, the compressor cooler and the decomposing pipe and conveying pipe of the high-pressure decomposing tower are widely used.Bobina de alambre brillante de acero inoxidable 304L
Although duplex stainless steel came out later, it developed very rapidly. Since it has both the advantages of austenitic stainless steel and ferritic stainless steel and can make up for their respective shortcomings, all countries attach great importance to the development and production of this kind of steel. Especially after 70s, the appearance of refining equipment has laid a foundation for the production of nitrogen and ultra-low carbon duplex stainless steel. Therefore, the dual phase stainless steel is obtained. Rapid development.7075 placa de chapa de aluminio
At present, duplex stainless steel has become an independent steel category with austenitic stainless steel, ferritic stainless steel and martensitic stainless steel. In Sweden, Germany, Japan, the United States and other countries, the development is very fast. Our country started developing duplex stainless steel in the middle of 70s. Because the production of duplex stainless steel is very difficult, it develops slowly in our country. With the production of VOD furnaces and AOD furnaces for stainless steel production in China, large vacuum induction furnaces have been put into production in large quantities, thus promoting the production and development of duplex stainless steel in China.Barra redonda de acero inoxidable maciza aisi 304
