Stainless steel coil is widely used in chemical industry， food， medicine， papermaking， petroleum， atomic energy and other industries，Stainless steel square tube as well as various parts of buildings kitchenware，316L stainless steel square pipeProfessional standards for Industry Segmentation vehicles and household appliances. stainless steel coil is divided into austenitic stainless steel cold rolled coil and stainless steel hot rolled coil. stainless steel (coil) plate features: beautiful surface and diversified use possibilities; Good corrosion resistance; Longer and more durable than ordinary steel; Good corrosion resistance; High temperature oxidation resistance and high strength， so it can resist fire; Good plasticity and welding performance. It has excellent rust and corrosion resistance good intergranular corrosion resistance and good processing performance.
6: stainless steel strip (stainless steel coil): or coil， coil， coil， plate coil. There are many names， and the hardness of the strip also varies from dozens to hundreds. Customers need to determine which hardness to use before purchasing. (K mirror luminosity)
mAustenitic stainless steel has good resistance to uniform corrosion， but there are still the following problems in local corrosion resistance: intergranular corrosion of austenitic stainless steel. Austenitic stainless steel will have intergranular corrosion when it is kept warm at ~ ℃ or cooled slowly. The higher the carbon content， the greater the tendency of intergranular corrosion. In addition， intergranular corrosion also occurs in the heat affected zone of the weldment. This is due to the precipitation of Cr rich CrC on the grain boundary. The chromium poor area is formed in the surrounding matrix，Stainless steel square tube which is caused by corrosion of the primary cell. This intergranular corrosion phenomenon also exists in the ferritic stainless steel mentioned above.
The stainless steel strip is supplied in coils， also known as strip steel. It is divided into hot rolling and cold rolling， stainless steel belt， stainless steel belt， stainless steel belt， stainless steel belt， stainless steel belt， J stainless steel belt， S stainless steel belt L stainless steel belt， L stainless steel belt，Stainless steel square tube S stainless steel belt， stainless steel iron belt，316L stainless steel square pipeProfessional standards for Industry Segmentation etc! Thickness: .mm-mm， width: mm-mm， can be customized without standard!
PSalkanIf you want to choose a high-quality stainless steel pipe water supply pipe you should first see whether its material is superior. Stainless steel is a material with strong corrosion resistance and high sanitation and cleanliness. Not only the outer wall is very beautiful， but also very smooth and smooth， and the incision is smooth. There will be obvious differences in material between the advantages and disadvantages of stainless steel pipe water supply pipe.
Lr SPHDSPHD—& mdash; Hot rolled steel plate and strip for stamping.
Theoretical weight of stainless steel pipe: w = outer diameter - wall thickness x wall thickness x..
Remarks: to ensure the nickel content of stainless steel strip and the mechanical properties of stainless steel strip， material certificate (Baogang material)， Japan Nippon Steel Material Certificate (Nippon Steel material)， SGS report，tisco stainless steel sheet,taigang stainless steel sheet,stainless steel sheet,stainless steel coil,stainless steel strip,stainless steel tube-TISCO Stainless Steel Co.,Ltd etc. can be provided.
aModel & mdash; It is easier to cut by adding a small amount of sulfur and phosphorus.
KMold cost: specifications are commonly used but not commonly used. Common specifications are rapid turnover and low mold sharing cost. Because of low utilization rate and high cost sharing， it is a special product manufacturing enterprise integrating R & D， sales and service. It has long been specialized in selling L stainless steel pipe， s stainless steel pipe and L stainless steel pipe. Therefore， the specification of a group of slightly larger formed pipes used in the production of pipe molds is about -.
RMeticulous workmanshipThe inner and outer surfaces of precision stainless steel pipe and thick wall pipe shall be free of cracks， folds， crazing， cracks， rolling folds， delamination， scabs and other defects， which need to be completely removed (unless they are specially used for machining) And after removing the stainless steel pipe wall， the wall thickness and outer diameter shall not exceed the negative deviation. As long as some minor surface defects that do not exceed the allowable negative deviation do not need to be removed.
mZChinas numbering rules adopt the use of element symbols and Chinese pinyin. Open hearth steel: P， boiling steel: killed steel: class a steel: T: Special: ball joint steel and spring steel， such as crm
There are kinds of hot rolled (hot extruded) steel pipes with a diameter of ~ mm， kinds of wall thickness of ~ mm， kinds of cold drawn (rolled) steel pipes with a diameter of ~ mm and kinds of wall thickness of . ~ mm.
According to rolling， it can be divided into hot rolled， hot extruded and cold drawn (rolled) stainless steel pipes.
Direct labornThe Chinese brand of stainless steel plate is crnimoti (CrNiMoTi with paper should also be this brand). The new brand is crnimoti stainless steel plate. The stainless steel plate is added with Ti in SUS steel to improve the intergranular corrosion resistance. It is applied to the equipment of， phosphoric acid， acetic acid and acetic acid.
XFor business people， of course， it is better to spend less under feasible conditions. For goods such as stainless steel pipes， we can often see that there will be packaging film bags on them. Although they are not heavy， if there are a large number of single purchases， they will also produce certain economic expenses， but why do many people clearly dislike this thing on stainless steel pipes， xincoral Xiaobian will tell you why stainless steel pipes need packaging bags.
HL polishing with appropriate particle size abrasive material to make the surface show continuous grinding lines.
oCorrosion test: the industrial corrosion-resistant steel pipes provided shall be tested for corrosion resistance according to the standard provisions or the corrosion agreed by both parties， and there shall be no tendency of intergranular corrosion.
yDProduction process of hot rolled stainless steel strip / coil: . Pickling → . High temperature rolling → . Process lubrication → . Annealing → . Leveling → ⒍ fine cutting → ⒎ packaging → . Reach customers.
It is generally suitable for the welding of thin plates below mm， with the characteristics of beautiful weld formation and small welding deformation.
