  · Rotary shaft, press roller, blade, impeller, etc. in high-strength corrosion-resistant environment.

7 series & mdash; Chromium nickel austenitic stainless steel.

vIn the building water supply pipe system, due to the end of the glorious history of galvanized steel pipe,Stainless steel pipe various new plastic pipes and composite pipes have developed rapidly,430 stainless steel stripWhat are the applicable industries and functional features but various pipes still have some deficiencies in varying degrees, which are far from fully meeting the needs of water supply pipe system and the national requirements for drinking water and related water quality. Therefore, relevant experts: building water supply pipes will eventually return to the era of metal pipes. According to foreign application experience, stainless steel pipe is recognized as one of the pipes with good comprehensive performance in metal pipe.

Someone asked whether the stainless steel pipe was rusted and caused toxic problems?

KManda luyongOrigin: domestic and imported (Sweden, Japan, Finland, South Korea, South Africa and Taiwan); classified according to the thickness of thin plate (.mm-mm), medium plate (mm-mm),Stainless steel pipe then slightly tighten the piece, and then rotate it for two circles until it is cut off. It must not be enough to allow personal strength to be in place at one time to lock the piece to cut off the pipe, otherwise the pipe end will be cut off, and the pipe fittings or rubber rings cannot be inserted; After the pipe above DN is cut, the internal and external burrs must be removed with a hand grinder and an appropriate outer slope opening shall be opened at the same time to avoid damaging the sealing ring.

  — It is easier to cut by adding a small amount of sulfur and phosphorus.

tModel & mdash; The corrosion resistance is the same, and the strength is better because the carbon content is relatively high.

AHigh yield strength can be obtained after,Stainless steel pipe which belongs to hard stainless steel. A common application example is & ldquo; Shaving blade & rdquo;. There are three common models: C and f (easy to process).

QFocus on Development  — It is easier to cut by adding a small amount of sulfur and phosphorus.

dF identification number and indication use international chemical element symbols and national symbols to indicate chemical composition. For a long time stainless steel plate, stainless steel coil,430 stainless steel stripWhat are the applicable industries and functional features stainless steel belt and stainless steel pipe have complete products, excellent quality and favorable price. Use letters to indicate composition content: for example, China and Russia use fixed digits to indicate steel series or numbers; for example, the United States, Japan, series, which only indicates the purpose.

Japanese cold rolled non oriented silicon steel strip consists of nominal thickness (expanded by times) + code a + iron loss guarantee value (the value after expanding the iron loss value when the frequency is Hz and the large magnetic flux density is T by times). Provide various brand products such as stainless steel plate, stainless steel coil,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 stainless steel belt and stainless steel pipe for a long time. The products of designated dealers are complete and the quality is guaranteed. For example, a means that the thickness is .mm and the iron loss guarantee value is ≤ cold rolled non oriented silicon steel strip.

Spcespce & mdash; & mdash; refers to cold-rolled carbon steel sheet and strip for deep drawing, equivalent to China Al () deep drawing steel. If it is necessary to ensure non aging property, add n at the end of the brand as spcen. Quenching and tempering code of cold-rolled carbon steel sheet and strip: annealing status is a, standard quenching and tempering is s, / hard is / , hard is / , hard is . Surface processing code: dull finish rolling is D, bright finish rolling is B. spcc-sd represents cold-rolled carbon sheet generally used for standard quenching and tempering and matt finish rolling. Another example is spcct-sb It refers to cold-rolled carbon sheet with standard quenching and tempering and bright processing and required to ensure mechanical properties.

Home page recommendationcIn order to ensure that the mechanical properties such as yield strength, tensile strength, elongation and hardness of various stainless steel coils meet the requirements, the stainless steel coils must undergo heat treatment such as annealing, solution treatment and aging treatment before delivery. The corrosion resistance of stainless steel coil mainly depends on

MStabilization treatment. Generally, it is used for - steel containing Ti and Nb in the solid solution treatment line. After the solid treatment, the steel is heated to ~ ℃ for heat preservation and air cooling. At this time the carbides of Cr are completely dissolved, while the carbides of titanium removal are not completely dissolved, and they are fully precipitated during the cooling process, making it impossible for the carbon to form chromium carbides again. It specializes in selling L stainless steel pipe, Guarantee service. Guarantee quality. Your satisfaction is our pursuit! Welcome to inquire. Therefore, intergranular corrosion is effectively eliminated.

Cold rolled steel strip shall be delivered in the state of heat treatment (annealing, normalizing and tempering after normalizing), and shall be delivered smoothly.

iThe rolling of cold drawn (rolled) seamless steel pipe is more complex than that of hot rolled (extruded seamless steel pipe). The first three steps of their production process are basically the same. The difference starts from the fourth step. After the round tube blank is emptied, it needs to be started and annealed. After annealing, pickling shall be carried out with special acid. After pickling, apply oil. Then it is followed by multi pass cold drawing (cold rolling) and special heat treatment. After heat treatment, it will be straightened.

yE series & mdash; Ferritic and martensitic stainless steel.

In order to prevent water from serious pollution during storage and transportation, the water industry now generally uses stainless steel pipes to store and transport water. Because stainless steel pipes have anti rust, high temperature and high pressure resistance and good sanitary performance, stainless steel pipes are slowly used in the industrial field!.
