The origin of magnetic stainless steel

According to research materials physics, magnetic magnetic stainless steel metal structures from the electron spin, electron spin quantum mechanical properties belong, either stainless steel 304 can also be "down." Ferromagnetic metals, electronics automatically rotated in the same direction, while the anti-ferromagnetic metal material, some of the electrons in the pattern for the rule, and the electrons moving in the opposite direction or adjacent Stainless steel factory spin, but triangular crystal the electronic grid, because each of the two triangles are electron spin in the same direction must therefore spin structure does not exist.

magnetic stainless steel sheet deep drawing parts

1 large size stainless steel deep drawing stainless steel parts , not very large production volume, in order to save material , should use cast iron HT300, QT600-2 , etc., as convex and concave mold materials, may also be of special cast iron .
2 , small and medium size magnetic stainless steel sheet deep drawing parts , copper based alloys generally used as mold material, such as aluminum bronze, aluminum and iron bronze, phosphor bronze .
3 , for the smaller sized stainless steel deep drawing parts , the choice of carbide YG8, YG15 for the die , W18Cr4V as punch proved when drawing die radius and the inner wall of the aneurysm is not easy to form a bond .
4 , the use of silicon nitride ceramic molds for stainless steel deep drawing get better results , because the magnetism stainless steel is a typical inorganic non-metallic materials , and stainless steel vary widely , but it is very hard , strong wear resistance , not plastic deformation occurs , which can effectively overcome the adhesion of the die and the workpiece significantly improve die life.

magnetic stainless steel furnace safety maintenance

Hydrogen as protective gas furnace . Seals required to achieve 10-6 th grade . Small amounts of air stainless steel sheets into the atmosphere will destroy protection , resulting in oxidation of the strip . Once the hydrogen leak , rising accumulate in the tower building structure will be very dangerous. So to take foolproof measures to ensure safety. To this end, the stove must have the following means :
In the steel import and export side sealing device is equipped with a flame detector ;
Monitoring furnace conditions ( temperature, pressure ) system ;
Devices and automatic emergency measure nitrogen purge ;
Hydrogen pressure monitoring equipment and automatic emergency measures ;
Equipment and automatic fire magnetic stainless steel sheets system emergency measures ;
Fire extinguishing the building , forced ventilation measures ; fire alarm center.

magnetic stainless steel sheet site together

There remind noteworthy point is that , after more than a week of rapid correction, the current construction steel market has been close to cost price, the price will of the next business may be reduced from the previous month . 321 stainless steel plate manufacturers magnetic stainless ex-factory launched a new round of " flat ", after the start of the site together with warmer weather will gradually increase, demand will improve.
China stainless steel mesh editing relevant agencies informed analysts believe that the country in mid- February average daily crude steel production exceeded 200 million tons, this is the first time since last October . On the one hand is the pressure of both steel production and inventory ; hand downstream demand in the steel industry is still not overly magnetic stainless steel. In the steel overcapacity in the background, even if macroeconomic been warmer, it is not enough to improve the operational status of the entire steel industry fundamentally . Steel City is estimated to weak consolidation pattern based.

magnetic stainless steel sheet by the structure

1 , multi- spot welding filter sheet : This product is mainly used by the process of stainless steel filter film . 2 , qiyi magnetic stainless steel sheet edge filter . Stainless steel sheet according to the shape of the filter : rectangular, round, circular , from the shape , waist and shaped .
Stainless steel filter sheet by the structure : single network, multi-layer composite filter sheet , combined filter film .
Stainless steel sheet by layers of filter : single, double, three, four , five, layers.
Stainless steel filter sheet main material : stainless steel sheet metal filter. ( 20 to 800 mesh ) .
Stainless steel filter sheet for the industry: Widely used in " chemical fiber spinning , staple fiber , microfiber , leather, non-woven, plastic granulator (pvc cable jacket material . ) , Sheet extrusion (PEPPABSPS) , masterbatch , rubber "and melt filtration.

Identification of magnetic stainless steel sheets mesh material basics

Today, the market is not stainless steel mesh vane manufacturers untidy mess , there is no unified brand prices. Pricing businesses generally rely on stainless steel mesh material , mesh size , weight, price and other factors . Similarly 80 mesh qiyi magnetic stainless steel mesh specifications, good between 35-45 yuan per square meter , the average 20-25 million, so poor on $ 15. This is such a huge price difference because the stainless steel mesh of different materials, the general absence of nickel , two nickel, nickel- 4 , 304,304 L, 316,316 L and other materials. Nickel nickel content stainless steel mesh different different grades of stainless steel 200 series 201 models will be mixed with manganese and nickel content is low , the price is relatively low , relatively easy to rust ; 304 and 300 series models only chrome and stainless steel coils manufacturers two elements of nickel , nickel is generally accounted for 8 % ratio , which ensures the stability of the stainless steel . As nickel is widely used in industrial elements , the higher the price , so different content raises the price difference .
