　　SPCCSPCC—& mdash; Cold rolled carbon steel sheet and strip are generally used,Stainless steel bowl with magnetic, which is equivalent to q195a. The third letter C is the abbreviation of cold. When it is necessary to ensure the tensile test, add t at the end of the brand as spcct.

At low temperature, the quality of professional stainless steel plate, coil, strip and tube is guaranteed. The company is professional, timely and cost-effective. It has become the first choice brand for many wire products. Welcome to buy! Ferritic stainless steel tubes have low-temperature brittleness like carbon steel, while austenitic steel does not. Therefore, ferritic or martensitic stainless steels have low-temperature brittleness Austenitic stainless steel or nickel base alloy does not show low temperature brittleness. Sus410 (13Cr), SUS430 of ferritic stainless steel pipe (18cr) and others show a sharp drop in impact value at low temperature. Therefore, high purification process can be considered. With the help of grade C and N when the embrittlement temperature is improved in the range of - 50 ℃ to - 100 ℃, it is possible to use it in freezing related projects Sus430lx (18cr Ti, Nb LC) and sus436l (18cr Mo Ti, Nb LC) have been applied to frozen shells. Ferritic stainless steel has a body centered cubic structure. When the material properties become weak, sharp cracks will expand rapidly and cause brittleness. Austenitic stainless steel will not produce brittleness because it has a face centered cubic structure. Austrian stainless steel SUSL (18cr-9ni LC) is used And SUSL (18cr-12ni-2mo-lc) show that they still have superior impact characteristics at low temperature. However pay attention to the precipitation of ferrite or martensite due to processing, and the tendency of embrittlement due to sensitization and carbide or & sigma; equal heterogeneous precipitation.

.Austenitic stainless steel. It contains more than 18% chromium, about 8% nickel and a small amount of molybdenum, titanium, nitrogen and other elements. Good comprehensive performance and resistance to corrosion of various media.

According to the specification, the specification of stainless steel pipe is mainly based on gb14975-94 stainless steel seamless steel pipe. The general length (indefinite length) of precision stainless steel pipe and thick wall pipe is 5-10m for hot-rolled steel pipe and 1m or more for hot-rolled steel pipe. The wall thickness of cold drawn (rolled) stainless steel pipe is 0.5-0mm and the length is 0-7m; the wall thickness of stainless steel pipe is greater than 0mm and the length is 5-8m.

However, stainless steel is relative, and it is just ordinary stainless steel. It's better not to use it in a particularly polluted environment. You can rest assured to use stainless steel pipes in your daily life.

After the installation of stainless steel water pipe cleaning pipeline, it is recommended to use 3% potassium permanganate for disinfection. It is strictly prohibited to use bleaching water for disinfection, and clean it with clean water after disinfection. If it is not put into use for a short time, compressed air must be used to blow out the residual water in the pipe, so as to prevent the corrosion reaction between oxygen free in the pipe and other media.

The 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 5-sulfosalicylic acid can completely remove the oxide layer on the surface of stainless steel The effect of adsorbing complex stabilizer 5-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 100 ℃ and strain rate of 0.01 ~ 5 s-1. 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 tube and the experimental value is 0.986 88, and the average relative error is only 6%. The model can better predict the deformation resistance of L stainless steel during thermal deformation. The dynamic recrystallization behavior of s stainless steel tube is easy to occur under the processing conditions of high temperature and low speed,

Austenitic stainless steel is generally used for manufacturing and manufacturing chemical equipment components, low-temperature equipment components in refrigeration industry, and can be used as stainless steel spring and clock spring after deformation strengthening.

5cm thick stainless steel plate shall be processed with special cutting tools, such as laser cutting machine with large wattage

Direct labor.2. Raw material problem of stainless steel pipe. If the hardness is too low, it is not easy to polish (BQ is not good). If the hardness is too low, orange peel is easy to appear on the surface during deep drawing, which affects BQ performance. BQ with high hardness is relatively good.

Theoretical weight: Cr Ni austenitic stainless steel austenitic stainless steel (kg / M) s-wall thickness (mm)

Basic weight (density) / kg of steel plate: SPCC & mdash& mdash; Cold rolled carbon steel sheet and strip are generally used, which is equivalent to q195a. The third letter C is the abbreviation of cold. When it is necessary to ensure the tensile test, the recrystallization temperature drops to 650 ℃, and the recrystallization annealing temperature of cold deformed austenitic stainless steel is 850 ~ 1050 ℃. At 850 ℃, it needs to be kept warm for 3h, fully burned at 1050 ℃, and then water-cooled.

In conclusion, when calculating the approximate weight of stainless steel pipe and multiplying it by the unit price, the price of 6m stainless steel pipe can be roughly obtained,2205 stainless steel belt, which can be used in the project budget.

.SPCC stainless steel belt is simply an extension of ultra-thin stainless steel plate. It is mainly a narrow and long steel plate produced to meet the needs of industrialized production of various metal or mechanical products in different industrial sectors.

Usage: widely used in automobile, tractor and other industries.

Seamless steel pipe belongs to the category with relatively high added value among steel pipe products, and the products involved in this case belong to the medium and high-end products of stainless steel pipe. According to incomplete statistics, in 2010, China exported about 20000 tons of stainless steel pipes to the EU, accounting for about 13% of the total exports of stainless steel pipes that year.
