If the surface of the stainless steel plate is scratched， and then gently wiped with a grinding wheel， and then the scratch will disappear.
1The electroless plated Pd film on the surface is mainly composed of PD， P and O. it has excellent corrosion resistance in boiling dilute solution. The corrosion rate is orders of magnitude lower than that of L stainless steel， and the corrosion rate is also significantly lower in mixed acid. In the boiling solution containing halogen ions when the concentration of halogen ions is very low
rSwanseaTheoretical weight of stainless steel pipe: w = outer diameter - wall thickness x wall thickness x .
Generally， a protective film will be attached to the surface of stainless steel plate to ensure the luster of the surface and prevent being scratched by hard objects. It can also effectively prevent scratching during transportation. The outer protective film is also a very important point. If the protective film with poor quality is placed for a long time，316L нержавеющая сталь the protective film will be damaged
JDumagateUse flux coated welding wire (self shielded welding wire) for backing TIG welding.
Ul stainless steel belt，Raleigh305 stainless steel pipeThe black kinetic energy weakens and the price rise is not sustainable J stainless steel belt， S stainless steel belt， L stainless steel belt， L stainless steel belt， S stainless steel belt， stainless steel iron belt， etc! Thickness: .mm-mm， width: mm-mm， can be customized without standard!
According to the strict requirements，316L нержавеющая сталь new stainless steel is being developed. Due to the continuous improvement of production efficiency and quality， stainless steel has become one of the cost-effective materials selected by architects.
Poor there will be obvious differences in material first.
q. 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 the performance of BQ. BQ with high hardness is relatively good.
OThe back is blocked with blocking plate for ventilation protection; Only soluble paper or the combination of soluble paper and blocking plate is used for blocking ventilation protection; Use flux cored wire for backing TIG welding.
NProfessional is kingWith the advantages and good performance of stainless steel， there is an increasing demand in the fields of kitchen equipment， workbench and utensils in the food industry， medical equipment， tableware and towel rack in daily life， bracket of refrigerator and so on.
zZCompared with the common structural materials of nuclear power，316L нержавеющая сталь it can be seen that the creep performance of several materials is better than that of ordinary materials under all test conditions. After hours of test， the total strain does not exceed .%. This curve is relatively stable and has small fluctuation，Raleigh305 stainless steel pipeThe black kinetic energy weakens and the price rise is not sustainable indicating that the test data is stable and reliable.
Only 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)
First level， reaching the international advanced level of similar products Until submerged.
Installation workshIn the building water supply pipe system due to the end of the glorious history of galvanized steel pipe， various new plastic pipes and composite pipes have developed rapidly， 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 products
RThe external anti-corrosion coating of stainless steel shall be galvanized and epoxy asphalt coating or coating with higher requirements according to the soil conditions of the pipe laying ground.
Stainless steel， i.e. one thousandth of stainless steel (rc and cc)， i.e. stainless steel; .%， such as CrNi，нержавеющая сталь листовой, нержавеющая сталь рулон, нержавеющая сталь, нержавеющая сталь трубы, нержавеющая сталь стержни - китайская Тай - сталь сталь ооо ultra-low carbon C & le; .% if the international stainless steel mark， the American Iron and Steel Institute uses three digits to mark various standard grades
rSwanseaConsidering the cost， the thickness of is generally . ~ .
uIWith the development of social economy， the application of stainless steel pipe has been more and more widely popularized. It will bring new changes in various fields.
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， and the creep performance is better under this condition. Compare this result with several other results
