Magnetic stainless steel sheets classification and organization structure of the

Magnetic stainless steel sheets atomic magnetic moment offset each other without closed magnetic moment. But when subjected to external magnetic field, the original in the thermal agitation mixed arrangement of the atomic magnetic moment is also subject to a magnetic stainless steel sheets  field to make the magnetic field aligned and hot trend with the anarchy Sao action arrangement, so the effect of magnetic stainless steel sheets is the total magnetic component in certain external magnetic field direction. Thus the magnetic susceptibility (magnetization and the magnetic field strength) become positive, but the value is also very small, magnetic stainlesssteel generally paramagnetic magnetic material rate is about one hundred thousand points, and increases with decreasing temperature. Magnetic stainless steel sheets is commonly used as a most decorative tube plate of stainless steel is Austenitic 304 material, generally speaking is stainless steelp late suppliers  or weakly magnetic, but caused by smelting chemical composition fluctuation or the processing status of different magnetic properties may also appear, but this can not be considered to be counterfeit or substandard.

The physical phenomenon of magnetic stainless steel and organization structure

Magnetic stainless steel is mainly used for high temperature applications, high temperature application magnetic stainless steel  with strong anti sensitization, to prevent corrosion in the low temperature grain. High strength, corrosion resistance and bending performance, excellent toughness of welding heat affected zone of high strength stainless steel plate. Reuse containing Mo, B and so on, can significantly improve the performance of the welding part stamping process. Mechanical yield strength, Magnetic stainless steel sheets tensile strength, elongation and hardness of magnetic stainless steel to meet the requirements of steel plate must be after annealing, solid solution treatment, aging treatment and other heat treatment before delivery. The composition of the alloy magnetic stainless steel corrosion depends primarily on its (chrome, nickel, titanium, silicon and aluminum) and internal organizational structure, played a major role in the CR. Chromium has the very high chemical stability, can form a passivation film on the steel surface, tainless Steel Sheets the metal and isolated, protect the steel by oxidation, enhance the steel corrosion resistance. Passivation membrane destruction, the corrosion resistance will decline.

Magnetic stainless why magnetic

Many customers often think that the magnet adsorption of stainless steel material, verify the authenticity of the advantages and disadvantages, don't smoke non-magnetic, that is good, magnetic stainless steel sheets  goods at a fair price; the suction magnetic, that is fake fake. In fact, this is an extremely one-sided, not practical error method of identification, I hope the following contents will be helpful to you! Many kinds of stainless steel, room temperature according to the organizational structure can be divided into several categories: 1 austenitic: such as 304, 321, 316, 310; 2 martensite or ferrite such as: 430, 420, 410; austenite is non-magnetic or weak magnetic properties, martensite or ferrite is a magnetic. Magnetic stainless is commonly used as a decorative stainless steel  pipe, stainless steel plate is most of austenitic stainless steel 304 material, generally speaking is non-magnetic or weakly magnetic, but caused by smelting chemical composition fluctuation or the processing status of different magnetic stainlesssteel  properties may also appear, but it cannot be considered to take card or unqualified, what reason is this? Austenite is the above-mentioned non-magnetic or weakly magnetic, and martensite or ferrite is a magnetic, because smelting when segregation or improper heat treatment, will cause a small amount of martensite austenite stainless steel in 304 body or ferrite. In this way, will magnetic stainless with a weak magnetic. In addition, magnetic stainless after cold working, organizational structure will be transformed to martensite, the greater the degree of cold deformation, the more the martensite transformation, the greater the magnetic properties of steel. Like a lot of the strip, the production of phi 103 tube, no obvious induction, the production of pipe. Because of cold bending deformation of large stainless steelp late suppliers  is obvious, producing rectangular tube due to deformation than the cylinder, especially the angle of deformation, more intense magnetic more obvious. Magnetic to completely eliminate the causes of 304 steel, can be opened through the high temperature solution treatment to restore the stability of austenite, thereby eliminating magnetic. In particular, magnetic because it causes 304 stainless steel, and other materials such as stainless steel, carbon steel, magnetic 430 is not the same level, that is to say the magnetic steel 304 always showed a weak magnetic.

The design concept of magnetic stainless steel sheets

Magnetic stainless steel sheets, completely changed the traditional impression of the iron and steel enterprises. "The cold rolling plant to gardens, this is not an exaggeration." magnetic stainless steel sheets  of environmental protection way thinking decided "domestic first established the cause of Environmental Protection Industry Development Department of the iron and steel enterprises, according to the foreign advanced experience to integrate all environmental management department. Magnetic stainless steel sheets from the concept of environmental protection work, to improve pollution control from the first to the development of the stainless steel  industry height. Shougang environmental protection industrialization is the idea of comprehensive utilization of Shougang internal environmental resources." The cause of environmental protection industry development department chief engineer Liao Hongqiang introduced to the "Chinese stainless steel net" reporter. The enterprises have to implement circular economy projects energy-saving emission reduction as a necessary condition for the development of enterprises. As development of combination of iron and steel industry in Hebei area of Qian'an, magnetic stainless steel sheets built the first national metallurgical enterprises circular economy industrial park, focused on building a stainless steelp late suppliers  slag treatment, tail slag brick, primary purification, blast furnace slag powder of steel slag, dust and mud concentrated treatment of resource utilization, comprehensive utilization of waste oil such as project 11, caused great concern in the domestic industry, the market promotion of independent R & D technology has played an exemplary role greatly.

The development of magnetic stainless steel

The stainless steel mesh editing was informed that at present, the magnetic stainless steel has reached 76%, the pipeline Water Leakage rate from the original 14.7% to the current 7.5%. Osaka magnetic stainless steel  from the earthquake, stainless steel storage tank intact. Recently, developed a corrugated pipe joint, the stainless steel water pipeline construction cost reduced by 20%, the total cost reduction of 3%, Magnetic stainless steel sheets  the cost of repair 3/4. Magnetic stainless steel industry drives the stainless steel pump under, has a good market prospect, not only is civil stainless steel pump, or the industrial field demand of stainless steel magnetic  industrial pump. Expected stainless steel pump market in China in the past ten years up to 3000000000. By adding green stainless steel materials, stainless steel pump can become China's pump industry leading pioneer, for the development of the stainless steel pump industry in China do what little one can to help the Chinese stainless steel mesh editing was informed.

Magnetic stainless steel technology innovation development

The whole magnetic stainless introduction

The so-called magnetic stainless just referred to, and you say with and without an external magnetic field is not saying, magnetic stainless steel sheet  say is can be a magnet for! If the judge quality stainless steel to this method, you must suffer the! The reason can be magnetic stainless as 201, 430 of the materials are:, high carbon content, the magnetic stainless steel sheets  of easy to rust, advantages of high strength, Magnetic stainless such as 202, 304, 316 and other materials containing nickel, chromium, reason: materials, advantages and disadvantages of high cost, poor strength, corrosion resistance is strong, is: easy to stretch.
