2 physical properties chemical composition C: it is specified in, which is usually also called mo2ti or mechanical properties ys (MPA)
Stainless steel with domestic (imported) stainless steel belt: stainless steel coil belt, stainless steel spring belt, stainless steel stamping belt,Specializing in the production of stainless steel belt, stainless steel precision belt, stainless steel mirror belt, stainless steel cold rolling belt, stainless steel
.AUSTENITIC FERRITIC duplex stainless steel. It has the advantages of both austenitic and ferritic stainless steel, and has superplasticity. Martensitic stainless steel. High strength, but poor plasticity and weldability.
Characteristics and application 347h austenitic stainless heat strength steel has good corrosion resistance, welding performance and heat strength performance. 347h stainless steel is used for large boiler superheater, reheater, steam pipeline and petrochemical heat exchanger pipe fittings.
. SPHCSPHC—& mdash; In the first place, s is the abbreviation of steel, P is the abbreviation of plate, h is the abbreviation of hot heat, and C is the abbreviation of commercial. It generally represents hot-rolled steel plate and strip.
Oxygen plus gas flame can not cut stainless steel plate because stainless steel is not easy to be oxidized.
In polluted air (such as atmosphere containing a large amount of sulfide, carbon oxide and nitrogen oxide) in case of condensed water, acetic acid liquid points will be formed, which will lead to chemical corrosion.
In order to prevent water from serious pollution during storage and transportation, the water industry now generally uses stainless steel pipes to store and transport water. Because stainless steel pipes have anti rust, high temperature and high pressure resistance and good sanitary performance, stainless steel pipes are slowly used in the industrial field!.
Stainless steel why corrosion-resistant stainless steel decorative pipe, 201 stainless steel pipe stainless steel pipe, all metals react with oxygen in the atmosphere to form an oxide film on the surface. Unfortunately, the iron oxide formed on ordinary carbon steel continues to oxidize, expanding the corrosion and finally forming holes. The carbon steel surface can be guaranteed by electroplating with paint or oxidation resistant metals (e.g. zinc, nickel and chromium), but as is known, this protection is only a thin film. If the protective layer is, the steel below begins to rust.
The width of coiled material is variable, including 30mm.60mm.45mm.80mm.100mm.200mm, etc. it can also be divided according to customer requirements
Manufacturing cost.Cold rolled stainless steel strip; Stainless steel strip / coil & rdquo; As raw material, it is rolled by cold rolling mill at room temperature. General thickness & amp; lt; 0.1mm～3mm& gt;, Width & amp; lt; 100mm～2000mm& gt;； [& ldquo; cold rolled steel strip / coil & rdquo;] has the advantages of smooth and smooth surface, such as 20CrMnTi 60simn, (C content is expressed in tens of thousands)
If you want to choose a high-quality stainless steel pipe water supply pipe, you should first see whether its material is superior. Stainless steel is a material with strong corrosion resistance and high sanitation and cleanliness. Not only the outer wall is very beautiful, but also very smooth. There will be obvious differences in material first in terms of incision and whether the stainless steel pipe water supply pipe is good or bad.
L stainless steel pipe is also called 00Cr17Ni14Mo2 stainless steel pipe. 00Cr17Ni14Mo2 is an ultra-low carbon steel of 0Cr17Ni12Mo2. 00Cr17Ni14Mo2 has better intergranular corrosion resistance than 0cr17ni14mo2. It is usually used to manufacture industrial equipment such as chemical industry, chemical fertilizer and chemical fiber, such as containers, pipelines and structural parts.
Standard requirements.If the thickness of the steel plate is not enough, the professional stainless steel plate, stainless steel coil,SUS304 stainless steel pipe, stainless steel belt and stainless steel pipe are strictly tested and the quality is guaranteed. The preferential activities are in progress. Welcome to consult. It is easy to bend, which will affect the production of decorative plate. If the thickness is too large and the steel plate is too heavy, it will not only increase the cost of the steel plate, but also bring unnecessary difficulties to the operation. At the same time, the allowance that should be left during processing or use of stainless steel plate shall also be considered. The thickness of copper plate is not absolutely consistent but the thickness of the same steel plate shall be as consistent as possible. Generally, for medium-sized saw plate, the thickness tolerance is 0.05-0.15mm. If the requirements are too strict,7 mm stainless steel plate, the grinding cost will also increase. Generally, it is a structural steel plate with high resistance and high degree. The greater the mechanical damage resistance, the longer the service durability, but the grinding and processing cost is also relatively high.
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, which affects BQ performance. BQ with high hardness is relatively good.
Good corrosion resistance, suitable for a variety of media; The addition of Mo improves the corrosion resistance to reducing salts; It is resistant to marine and industrial atmospheric erosion, and can be used in seawater equipment; Due to its low carbon content, it has excellent grain boundary corrosion resistance; It can be used in pulp and paper machinery; Good processability and weldability.
.The folded stainless steel hot rolled strip is hot rolled into a strip with a thickness of 80mm-00mm and a width of 50mm-1200mm.
Compared with traditional steel, stainless steel can not only ensure high strength and weight ratio, but also have good plasticity, formability and weldability. It is the first choice for car frame. Stainless steel with superior performance can create cars with light weight, strong resistance, high safety and long service life. Such frames can be recycled and reused. It can not only save costs, but also save resources. And some other auto parts are also made of stainless steel. Stainless steel has a great potential market in the whole automobile industry!
When transporting domestic and drinking water the pipeline shall not pass through the toxic pollution area. If necessary, protective measures shall be taken.
