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 and its dynamic recrystallization volume fraction and strain change in S shape. The value obtained by the model is consistent with the experimental data The volume fraction of dynamic recrystallization of s stainless steel tube during hot working can be well. Dense palladium membrane was prepared on porous stainless steel substrate with pore size of 5 & mu; m by electroplating and the combination of the two. The palladium membrane on the surface of porous stainless steel was characterized by seeds and XRD. The results show that the pretreatment is completed with 0.1 GL PdCl2 solution A pure palladium film can be prepared by electroless plating of porous stainless steel and electroplating with palladium ammonia solution with palladium content of 17 GL,
.When the stainless steel pipe with solid core welding wire is prefabricated, the welded junction can usually be rotated for welding, and the ventilation is very easy. At this time, the blocking plate is usually used to block both sides of the welded junction in the pipe, and the bottom welding is carried out for the protection of ventilation (see Table 1) and the outside is blocked with adhesive cloth.
In order to obtain seamless pipes with smaller size and better quality, cold rolling, cold drawing or a combination of both must be used. Cold rolling is usually carried out on a two high mill. The steel pipe is rolled in an annular pass composed of variable section circular groove and fixed conical plug. Cold drawing is usually carried out on a single chain or double chain cold drawing machine of 0.5 ~ 100t.
.It has lower linear coefficient than austenitic stainless steel and is close to carbon steel. It is suitable for connection with carbon steel and has important engineering significance, such as the production of composite plate or lining.
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, it is necessary to pay special attention when using at low temperature. As a way to improve the impact toughness of ferritic series stainless steel 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,X6crniti18-10 stainless steel plate, 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, such as automotive accessories. Good formability, but poor temperature resistance and corrosion resistance.
Shop around and choose affordable stainless steel water supply pipes. Comparing the prices of pipes sold by various companies, the transmission energy consumption of stainless steel pipe water supply pipe is low, which saves the transmission cost, so the price will not be too expensive.

Stainless steel is a very thin, firm, fine and stable chromium rich oxide film (protective film) formed on its surface. It prevents oxygen atoms from penetrating and oxidizing, and obtains corrosion resistance. Once this film is continuously damaged for some reason, oxygen atoms in the air or will continue to separate out, forming loose iron oxide. For a long time, stainless steel plate, stainless steel coil and stainless steel belt will be provided, Stainless steel pipe, a 20-year-old brand, has advantages in price and guaranteed quality! The metal surface is constantly corroded
Quality assurance.In the grades of Japanese steel (JIS Series), ordinary structural steel is mainly composed of three parts,Of stainless steel plate 201, which represent the material, such as s (steel) represents steel and f (ferrum) represents iron; The second part represents different shapes, such as P (plate) represents plate, t (tube) represents tube, and K (kogu) represents tool; The third part represents the characteristic number, which is generally low tensile strength. For example: SS400 & mdash& mdash; One s represents steel, and the second s represents & ldquo; Structure & rdquo; (structure), and the whole represents ordinary structural steel with tensile strength of 400MPa.

Stainless steel tube toxic chromium and nickel is not bad for you? Stainless steel contains a lot of chromium and nickel. Why is stainless steel still? The following Tianjin stainless steel pipe factory will answer for you: food grade stainless steel pipes will be corroded into spots for a long time if they are not soaked in acid (vinegar) and salt for a long time. Good stainless steel is a model and never rusts.
