Folding and editing this section of silicon steel strip grain oriented silicon steel strip, also known as cold rolled silicon steel strip for telecommunications industry, is a silicon steel strip with grain oriented structure and thickness less than .mm, which is used to manufacture various power transformers, pulse transformers, magnetic amplifiers,Stainless steel checkered plate converters and other iron cores with working frequency above Hz.

1  — Good ductility,Ocr19ni9ti stainless steel plateService first used for molding products. It can also be hardened rapidly by machining. Good weldability. The wear resistance and fatigue strength are better than those of stainless steel.

iModel & mdash; High strength cutting tool steel, with slightly higher carbon content, and the hardness can reach hrc. It 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).

Hydraulic saw grinding disc (manual saw wire cutting machine).

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

JnHot rolled silicon steel sheet hot rolled silicon steel sheet is represented by Dr, which is divided into low silicon steel (silicon content & le; %) and high silicon steel (silicon content & amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp

Wait. It can be seen that stainless steel has been widely used in heavy industry, daily necessities industry, architectural decoration and other industries. Due to the superior performance, we specialize in the sales of L stainless steel pipe,Stainless steel checkered plate s stainless steel pipe and L stainless steel pipe. The technology is advanced, the testing is strict the price is more affordable and more preferential. We welcome consultation.

In the building water supply pipe system, as the galvanized steel pipe has ended its glorious history of one hundred years, various new plastic pipes and composite pipes have developed rapidly. It specializes in the sales of stainless steel plate, stainless steel coil, stainless steel belt and stainless steel pipe. The technology is advanced the detection is strict, the price is more affordable and more preferential. Welcome to consult. However, there are still some deficiencies in various pipes to varying degrees, It is far from being able to fully meet the needs of water supply pipeline system and national requirements for drinking water and related

jThe main way to prevent stress corrosion of austenitic stainless steel is to add SI ~ % and keep the content of N below .% from smelting. In addition, the content of impurities such as P,Stainless steel checkered plate Sb, Bi and as should be minimized. In addition A-F dual phase steel can be selected,Ocr19ni9ti stainless steel plateService first which is insensitive to stress corrosion in Cl - and oh - media. When the initial micro crack encounters ferrite phase, it will not continue to expand, and the ferrite content should be % about.

OThe effect of different stabilizers on the stability of ferritic stainless steel during pickling in base solution was studied by means of weight loss curve and scanning electron microscope. The results show that under the experimental conditions, both complex stabilizer HF and adsorption complex stabilizer -sulfosalicylic acid can completely remove the oxide layer on the surface of stainless steel The effect of adsorbing complex stabilizer -sulfosalicylic acid is obviously better than that of complex stabilizer HF in the stability effect and the flatness of the research results on the properties and microstructure of stainless steel surface s stainless steel pipe after pickling. The deformation behavior at high temperature at ℃ and strain rate of . ~ s-. The rheological stress curve is drawn according to the compression experimental data; based on Arrhenius relationship and considering the strain Factor, an improved constitutive equation coupled with strain factor is established; combined with optical microscope (OM) The characteristics of microstructure during material deformation are observed; the dynamic recrystallization critical strain of L stainless steel is determined according to the work hardening rate flow stress curve, and the dynamic recrystallization volume fraction model is established based on the s stainless steel pipe equation. The results show that in the process of thermal deformation of s stainless steel pipe, the flow stress corresponding to lower temperature and faster strain rate is also large; the coupling of stress variable factors The correlation coefficient between the rheological stress of the constitutive model s stainless steel pipe and the experimental value is . , and the average relative error is only %. The model can better predict the deformation resistance of L stainless steel in the process of thermal deformation

fGIn polluted air (such as atmosphere containing a large amount of sulfide,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 carbon oxide and nitrogen oxide), in case of condensate, acetic acid liquid points are formed, causing chemical corrosion.

According to the steel structure, austenite ferrite ferrite martensite and precipitation hardening note: precipitation hardening (precipitation strengthening): refers to a heat treatment process in which the metal is hardened by the segregation zone of solute atoms in supersaturated solid solution and / or the desolved particles are dispersed in the matrix. For example, austenitic precipitated stainless steel can obtain high strength by precipitation hardening at ~ ℃ or ~ ℃ after solution treatment or cold working. That is, the supersaturated solid solution of some alloys is placed at room temperature or heated to more & amp; gt;& amp; gt;

Let PS be the external force at the yield point s and fo be the cross-sectional area of the sample, then the yield point & sigma; S = PS / fo (MPA), MPa is called MPa, PA: Pascal = n / M

Management DepartmentpThe internal and external greasy dirt and sundries at the pipe end shall be completely removed to keep the pipe inside the pipe fittings clean.

WModel & mdash; It has better temperature resistance.

The pipes for pipe cutting shall be professionally cut by stainless steel. Rotate it for two circles, 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.

nAfter the pipeline is installed and the pressure test is qualified, it is better to wash with low chloride ion water and disinfect with .% potassium permanganate.

yLMechanical properties when the steel or sample is stretched, when the stress exceeds the limit, even if the stress is no longer increased, the steel or sample continues to have obvious plastic deformation, which is called yield, and the small stress value when the yield phenomenon occurs is the yield point.
