310S stainless
310S stainlessSurface treatment difference: surface treatment is usually divided into polishing, wire drawing and wire drawing, and the cost is about 1 yuan and 1 meter. If it is thrown into the lens barrel, the magnetic induction peak with sinusoidal waveform is the unit weight iron loss value of 5t) + 100 times of thickness value. For example, dw470-50 represents cold-rolled non oriented silicon steel with iron loss value of 7W / kg and thickness of 0.5mm. Now the new model is 50W470.
.Model 440 & mdash; High strength cutting tool steel, with slightly higher carbon content, can obtain higher yield strength after appropriate heat treatment, and the hardness can reach 58hrc. It belongs to hard stainless steel. A common application example is & ldquo; Shaving blade & rdquo;. There are three common models: 440C and 440f (easy to process).
There are 45 kinds of hot rolled (hot) steel pipes with a diameter of 54 ~ 480mm, 36 kinds of wall thickness of 5 ~ 45mm, 65 kinds of cold drawn (rolled) steel pipes with a diameter of 6 ~ 200mm and 39 kinds of wall thickness of 0.5 ~ 21mm.
.600 Series&
Seamless steel pipe belongs to the category with relatively high added value among steel pipe products, and the products involved in this case belong to the medium and high-end products of stainless steel pipe. According to incomplete statistics, in 2010, China exported about 20000 tons of stainless steel pipes to the EU,Stainless steel mesh belt conveyor, accounting for about 13% of the total exports of stainless steel pipes that year.
The best choice is also frequently launched in the market. If you want to buy a stainless steel water supply pipe with quality assurance how should you choose?
In view of the external export difficulties, on the one hand, but it is important for China's stainless steel industry to continuously improve its quality level and comprehensively upgrade.
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.
430— Ferritic stainless steel for decoration, such as automotive accessories. Good formability, but poor temperature resistance and corrosion resistance.
details.In the building water supply pipe system, since the galvanized steel pipe has ended its glorious history of one hundred years, various new plastic pipes and composite pipes have developed rapidly. The professional stainless steel plate, stainless steel coil, stainless steel belt and stainless steel pipe have advanced technology, strict testing, more affordable price and more preferential treatment. Welcome to consult. However, there are still some deficiencies in various pipes to varying degrees It is far from fully meeting the needs of water supply pipeline system and national requirements for drinking water and related water quality. Therefore,219 stainless steel pipe, relevant experts: building water supply pipes will eventually return to the era of metal pipes. According to foreign application experience, stainless steel pipe is recognized as one of the pipes with good comprehensive performance in metal pipe. Chemical analysis: carry out chemical analysis on the chemical composition of the material, and the chemical composition meets the requirements
Stainless steel belt, stainless steel conveyor belt, stainless steel packing belt, stainless steel belt, stainless steel coil belt, ultra-thin stainless steel belt.
Origin: domestic and imported (Sweden, Japan, Finland, South Korea, South Africa and Taiwan); classified according to the thickness of thin plate (0.2mm-4mm), medium plate (4mm-20mm), thick plate (20mm-60mm) and extra thick plate, according to the production of hot-rolled steel plate and cold-rolled steel
Stainless steel pipe is a common material in stainless steel, with a density of 93 GCM, which is also called 188 stainless steel in the industry. High temperature resistance of 800 ℃ with the characteristics of good processing performance and high toughness, it is widely used in industry, furniture decoration industry and food and medical industry.
Excellent service.Before connecting the pipe fittings, mark the depth on the pipe first, so as to prevent it from being inserted in place and stuck.
The shape of pipe end stainless steel pipe can be divided into smooth pipe and threaded pipe (threaded steel pipe) according to the state of pipe end. Threading pipe can also be divided into ordinary threading pipe (pipe for conveying low pressure such as water and gas, which is connected by ordinary cylindrical or conical pipe thread) and special threaded pipe (pipe for petroleum and geological drilling,Quotation sheet of stainless steel pipe, which is connected by special thread for important threading pipe). For some special pipes, in order to make up for the impact of thread on the strength of pipe end the pipe end is usually thickened before threading (inner thickening, it is mainly divided into oil well pipe (casing, oil pipe and drill pipe), pipeline pipe, boiler pipe, mechanical structure pipe, hydraulic prop pipe, gas cylinder pipe, geological pipe, chemical pipe (high-pressure fertilizer pipe, petroleum cracking pipe) and marine pipe. Calculation formula for weight of stainless steel square tube: (nozzle perimeter 14 - actual thickness) actual thickness is 0.02491, of which 0.02491 is a constant converted from stainless steel density.
.All decreased in varying degrees, with an average decrease of 7%. In terms of varieties, the prices of construction wire rod and rebar, fell by 9% and 7% respectively, and the prices of medium and heavy plate and hot rolled coil fell by 7% and 7% respectively.
[hot rolled strip / sheet] has the advantages of low hardness, easy processing and good ductility.
Stainless steel pipe will rust? Stainless steel pipe is a food grade stainless steel pipe recognized by the state. It is not absolutely non rusting, but it is not easy to rust compared with other steel grades. Many people will think that the stainless steel pipe is not rusty, especially the stainless steel pipe has high nickel content, which is more difficult to rust. If it is rusty, whether it will be replaced by 201 stainless steel pipe, or there is a problem with the raw materials of the steel strip. In fact, these questions and judgments are one-sided views on the lack of understanding of stainless steel pipes. Stainless steel pipes may also produce rust and rust spots under certain conditions.
