Stainless stee
Stainless stee2. 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.
Summary of plate manufacturing method according to surface characteristics surface characteristics application silver white matte hot rolled to the specified thickness,8k304 mirror stainless steel plate, and then annealed and descaled. A rough and matte surface does not need surface gloss. Silver white cold rolled heat treatment and pickling 2D products are used for applications with lax surface requirements. For general materials, the gloss of deep drawing materials is stronger than that of D treatment, After finishing a light cold rolling with polishing roller, the general material Ba is as bright as a mirror. There is no standard, but it is usually the surface processing of bright annealing, and the surface reflectance is very high. For building materials,Stainless steel strapping, 100 ~ 200 # (unit) abrasive belt is used for kitchen coarse grinding to grind building materials, The polishing surface obtained by grinding with 150 ~ 180 # abrasive belt in the middle of the kitchen is the same as that obtained by fine grinding. The polishing surface is polished with 240 # abrasive belt. The ultra-fine grinding in the kitchen is polished with 320 # abrasive belt. The luster is similar to that of Ba. It is generally used for grinding with 400 # polishing wheel. It is used for construction. It is specialized in stainless steel plate, Stainless steel pipe quality assurance. New and old customers are welcome to consult during the preferential activities. HL hair line grinding in the kitchen is carried out by grinding materials with appropriate particle size for hair line grinding (150 ~ 240#). There are many buildings and building materials close to mirror grinding. 600# rotary polishing wheel is used for grinding for art, mirror grinding for decoration, mirror grinding for mirror, and polishing wheel is used for grinding reflector, For decoration, according to the purpose, bridge steel plate, boiler steel plate, shipbuilding steel plate, automobile steel plate, roof steel plate structural steel plate, electrical steel plate (silicon steel sheet), spring steel plate, special solar plate (Hairui special steel) are common Japanese brands in other steel plates for ordinary and mechanical structures.
.Adjust the ratio of austenite forming elements to ferrite forming elements in the steel to make it have austenite + ferrite dual phase structure,Price of 316L stainless steel pipe, in which ferrite accounts for 5% - 12%. This dual phase structure is not easy to produce intergranular corrosion.
The pipes for pipe cutting shall be professionally cut by stainless steel. Rotate it for two circles, then slightly tighten the piece, 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 DN65 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.
.Since the invention of stainless steel at the beginning of this century, stainless steel has integrated the image of modern materials and the excellent reputation in architectural applications, which makes its competitors envy. Stainless steel will not produce corrosion, pitting, corrosion or wear. Stainless steel is also one of the metal materials with high strength. Because stainless steel has good corrosion resistance, which is easy to process and manufacture parts, and can meet the needs of architects and structural designers.
Usage: widely used in automobile, tractor and other industries.
In view of the external export difficulties, on the one hand, China's stainless steel industry needs to improve, but it is important for China's stainless steel industry to continuously improve its quality level and comprehensively upgrade.
1: stainless steel plate: it can be divided into cold-rolled plate and hot-rolled plate. Its surface has bright surface, fog surface and matte surface. It is commonly known as stainless steel plate, it can also be plated with other light colors according to customer requirements. The main specifications of plates are: 1m * 1m, 1m * 2m, 22m * 44m, 5m * 3M, 5m * 6m. If customer demand is large, we can cut them according to customer size. In addition, we can replace wire drawing plate, anti sliding plate and electroplating plate
Marking: in order to make the steel pipe complete the socket of the pipe fitting, the length must be marked and marked at the pipe end.
Hot rolled belt stainless steel etching belt, stainless steel stretching belt, stainless steel polishing belt, stainless steel soft belt, stainless steel hard belt, stainless steel medium hard belt, stainless steel high temperature resistant belt, etc.
The cost is reasonable.The inventory of stainless steel pipes may be an important factor in market conditions. This is because at this stage, steel inventory has become an important index to investigate and judge the situation of stainless steel pipeline shopping malls, and has become a wind vane to judge the future market trend. What was the stock of stainless steel tubes at that time? It directly affects the air of shopping malls, and then distributes the business behavior of participants in shopping malls
The design shall be carried out according to the soil, water, grooved section, load conditions and other factors of the trench, which shall be firm and reliable to prevent collapse and support, and shall not hinder the pipe laying and pipe stabilization.
Stainless welded disc (grade I) gb1270-80 stainless steel pipe (grade I)
With the development of social economy, the application of stainless steel pipe has been more and more popular. It will bring new changes in various fields.
Product line.It has excellent stress corrosion cracking resistance. Even duplex stainless steel with low alloy content has higher stress corrosion cracking resistance than austenitic stainless steel, and the strength is better because the carbon content is relatively high.
%）.It means: 100 times of Dr + iron loss value (iron loss value per unit weight when 50Hz repeated magnetization and sinusoidal magnetic induction intensity is 5T) + 100 times of thickness value. For example, dr510-50 indicates that the iron loss value is hot-rolled silicon steel plate with thickness of 0.5mm. The grade of hot rolled silicon steel sheet for household appliances is expressed by JDR + iron loss value + thickness value, such as jdr540-50.
.2020303043310s, 331632404420, 430 and other materials.
After the pipeline is installed and the pressure test is qualified, it is better to wash with low chloride ion water and disinfect with 0.03% potassium permanganate.
Do a good job of preliminary data research. In the highly competitive market stainless steel pipe should go deep into the hinterland. It is essential and crucial to do a good job of pre market data research; Only by fully grasping consumer demand trends, habits and other data can we have more confidence to compete for market share. Therefore the editor of stainless steel pipe believes that in-depth data mining and comprehensive market analysis are powerful for stainless steel control manufacturers in this movement.
