The fingerprint treatment process can obtain fingerprint free effect in the treatment of stainless steel mirror plate， frosted plate and etching plate， and can improve the anti rust function.
Cold rolled non oriented silicon steel with a thickness of .mm is now represented as W.
Dubo， it can provide a reference for the new direction of stainless steel surface treatment， and has a certain practical guiding significance. The corrosion resistance and mechanism of chemical passivation， silicon treatment and composite treatment of martensitic stainless steel were studied in this paper. The comprehensive comparison of the research results shows that the four corrosion resistance tests show no rust
Thin plate (.mm-mm)， medium plate (mm-mm)， thick plate (mm-mm) extra thick plate according to the production of hot-rolled steel plate， cold-rolled steel plate according to the surface characteristics， the outline of the manufacturing method of surface characteristics， silver white matte， hot rolled to the specified thickness
Zinho Usage: it is widely used in automobile industry， aviation industry and other departments.
There is also a spectrometer detection method， which is a relatively simple and fast way.
The change of creep rate is shown in. When the temperature rises， the material maintains a low level of creep rate. Under the condition of ℃ and MPa，DuboXm21 professional stainless steel pipe， which shows little influence on the temperature and stress， and the creep performance is better under this condition. Compare this result with several other results
The low carbon content in the steel makes the carbon content in the steel lower than the saturated solubility of austenite in the equilibrium state，Dubo201 high quality stainless steel pipe， which fundamentally solves the problem of precipitation of chromium carbide (crc) on the grain boundary
There are three main forms of corrosion of stainless steel: chemical corrosion， electrochemical corrosion and stress corrosion. The parts with weak corrosion resistance in the passive film on the surface of stainless steel form pitting reaction and small holes due to self-excited reaction. In addition， chlorine ions are close to each other to form a strong corrosive solution
The slab solidified on the surface continues to be rapidly cooled through the secondary cooling section until the core becomes solid，Dubo434 stainless steel sheet， and the whole continuous casting process of stainless steel pipe fittings is completed.
Excellent serviceThe microstructure characteristics of the material during deformation were observed by optical microscope (OM); According to the work hardening rate flow stress curve， the dynamic recrystallization critical strain of L stainless steel is determined， and the dynamic recrystallization volume fraction model is established based on S stainless steel pipe equation. The results show that at S
. Surface defects of raw materials. Such as scratch， soaking， etc.
The removal technology of tritium remaining in the pipe wall was studied， and a set of tritium removal system was developed
Clean with neutral detergent. If the surface of stainless steel plate is stained with oily pollutants， it can be repeatedly scrubbed and cleaned with neutral detergent.
Where can I find it?It is possible to use it in freezing related engineering when the embrittlement temperature is improved in the range of - ℃ to - ℃. Recently， suslx (cr Ti， Nb LC) and susl have been applied to frozen shells. Ferritic stainless steel is body centered cubic junction
Delivery state of carbon structure: delivered in the state of heat treatment (annealing， normalizing， tempering after normalizing and high temperature tempering).
[hot rolled strip / sheet] has the advantages of low hardness， easy processing and good ductility.
DuboOnly soluble paper or the combination of soluble paper and blocking plate is used for blocking ventilation protection (i.e. solid core welding wire + TIG + water-soluble paper)
The installation of the stainless steel ceiling is very difficult and requires very professional personnel to do it well. If you are not professional it is easy to get dizzy and don"t know how to do it. The ceiling is also easy to collapse and cause accidents， which is not worth the loss. Professional matters should be handled by professional
Ping.
