The use of stainless steel plate is very extensive. With the use of stainless steel plate materials in construction and other industries, stainless steel plate smelting enterprises have begun to appear in many places. So how to smelt stainless steel plate, here are the non-oxidation method, oxidation method and return oxygen blowing method; three methods to smelt stainless steel plate. Nowadays, most of the methods we use are the return oxygen blowing method. This method uses scrap steel for direct smelting, which is not only low-cost but also highly efficient. At present, some developed countries in foreign countries also use returned materials in smelting stainless steel. Oxygen blowing method; the stainless steel used in this method occupies a large amount of raw materials, so if there is no stainless steel scrap resource, it will become a meal without rice. In response to this problem, some people have developed a one-step method for smelting stainless steel plates and pipes. This one-step method is one-step smelting of stainless steel in an electric furnace. Because the one-step method has very strict requirements on raw materials, the raw materials and energy media in production are consumed at high costs. high, and the smelting cycle...
When brown spots appear on the surface of the stainless steel coil, people are surprised that the stainless steel coil will not rust, and the rust is not the stainless steel coil, it may be a problem with the steel. In fact, this is a one-sided misconception about the lack of understanding of stainless steel coils. Stainless steel coils will also rust under certain conditions. Stainless steel coils have the ability to resist atmospheric oxidation, that is, non-rust, and also have the ability to resist corrosion in media containing acid, alkali, and salt, that is, corrosion resistance. However, the size of its corrosion resistance is changed with the chemical composition of the steel itself, the conditions of mutual use and the type of environmental media. For example, 304 has absolutely excellent corrosion resistance in a dry and clean atmosphere, but if it is moved to a seaside area, it will soon rust in the sea fog containing a lot of salt, while 316316l stainless steel coil is good performance. Therefore, it is not any kind of stainless steel coil that can resist corrosion and rust at any time. The stainless steel coil is a very thin, firm and fine stable...
Compared with austenitic 316L steel, 2205 duplex stainless steel has the following advantages. 1. The yield strength of 2205 dual-phase steel is more than double that of 316L austenitic stainless steel, and it has sufficient plasticity and toughness required for forming. The wall thickness of the pressure vessel manufactured by the 2205 stainless steel manufacturer is 30-50% lower than that of the 316L stainless steel pipe, which is conducive to reducing costs. 2. 2205 dual-phase steel has excellent resistance to stress corrosion cracking, especially in the marine environment containing chloride ions, stress corrosion is a prominent problem that austenitic stainless steel is difficult to solve. 3. The corrosion resistance of the common 2205 duplex steel in many media is due to the common 316L stainless steel, while the super duplex stainless steel has extremely high corrosion resistance, such as acetic acid, formic acid, etc. It can even replace high-alloy austenitic stainless steel pipes, and even corrosion-resistant alloys. 4. 2205 duplex steel has good local corrosion resistance. Compared with austenitic stainless steel with a similar alloy content, in view of the high strength and good corrosion resistance of 2205 duplex stainless steel, its wear resistance and corrosion fatigue resistance The properties...
There are many types of environmentally friendly stainless steel, among which 0Cr18Ni9 (304) has excellent corrosion properties, good resistance to intergranular corrosion, cold forming properties, low temperature properties and welding properties. Widely used in the manufacture of deep-drawn parts, acid-resistant pipes and containers. 00Cr19Ni10 (304l) has low carbon content and has better corrosion resistance and intergranular corrosion performance after welding than 304. It is used in the manufacture of equipment, containers, pipes and various parts and components that are not heat treated after welding in the chemical and power industries. Features and Uses 0Cr18Ni9(304) has excellent corrosion properties, good resistance to intergranular corrosion, cold forming properties, low temperature properties and welding properties.
