Q:What's the difference between stainless steel 304 and stainless steel 202?
304 stainless steel is a common stainless steel material, the density of 7.93 g/cm3, the industry is also called 18/8 stainless steel. High temperature resistance of 800 degrees, with good processability, high toughness characteristics, widely used in industry and furniture decoration industry and food and medical industry. The common marking methods in the field are 0Cr18Ni9, SUS304.
Q:Ask experts, 304 stainless steel pipe why rust?
Stainless steel is not easy to rust and has a lot to do with the composition of stainless steel. In addition to iron, stainless steel contains chromium, nickel, aluminum, silicon and so on. General stainless steel chromium content is generally not less than 12%, high even up to 18%. Steel added elements such as chromium, can change the performance of the steel, such as the molecular structure of steel more uniform on the surface of the steel is more easily to form a layer of dense oxide protective film, thereby greatly improving the ability of corrosion-resistant stainless steel. Therefore, stainless steel can resist fire, water, acid, alkali and various solutions to its corrosion, not rust. The scientists found that the internal structure of the steel is more uniform, various components more closely linked to the corrosion of the more difficult the invasion, also attached to the surface with a layer of oxide film, like iron and steel to wear armor, was not naturally easy to rust.
Q:How thick is the 3 stainless steel tube?
All units of steel default are mm mm. stainless steel 3 thick meaning, that is, the thickness of 3 mm mean
Q:What does "stainless steel pipe" DN mean?
Nominal diameter is the size of all piping accessories in the piping system. The nominal diameter is a convenient round integer for reference and is not strictly related to the processing size. The nominal diameter follows the letter "DN" followed by a number sign.
Q:What are the categories of stainless steel pipes with acid and alkali resistance?
Stainless steel is usually classified according to the organization of the matrix, as follows:The ferritic stainless steel (200 and 400) the chromium content in 15%~30%, with a body centered cubic crystal structure. This kind of steel does not contain nickel, sometimes also contain a small amount of Mo, Ti, Nb and other elements, this kind of steel has high heat conductivity, low expansion coefficient, good oxidation resistance and anti stress excellent characteristics of stress corrosion, used formanufacturingthecorrosionresistanceofthe atmosphere, water vapor, waterandoxidizing parts. Ferritic stainless steel prices are relatively low and stable, and has many unique characteristics and advantages, it has been proved that in many of the original that can only use austenitic stainless steel (300) application of ferritic stainless steel is a very excellent substitute materials, ferritic stainless steel containing nickel, the main elements of Cr (>10%) and iron, chromium stainless steel special corrosion resistant elements, its price is relatively stable.. Chromium 12% ~ 30%. Its corrosion resistance and toughness increase with the increase of chromium content, and the weldability is excellent.
Q:Where is the difference between seamless steel pipe or welded pipe?
Seamless steel tube is formed during rolling. Welded steel pipes need to be welded after coiling, and spiral welding and direct welding are generally used. Seamless performance is better, of course, the price is higher.
Q:304 stainless steel will rust it?
Why is stainless steel rust? When the stainless steel tube surface appear brown rust (point) when people are surprised: "the stainless steel does not rust, rust is stainless steel, steel may be a problem". In fact, this is a lack of understanding of stainless steel one-sided misconceptions. Stainless steel will rust under certain conditions.
Q:Why can it stainless steel be put together with carbon steel tube?
Potential difference: the stainless steel pipe with a more positive potential and the carbon steel pipe with negative potential are even connected. The stainless steel tube is cathode, and the carbon steel tube is anode. The greater the potential difference between the two, the greater the galvanic corrosion tendency.
Q:The difference between galvanized steel pipe and stainless steel pipe
Galvanized pipes are generally used for fire fighting and circulating water supply (non living water supply)
Q:What are the specifications of stainless steel decorative pipes?
The steel pipe seamless steel pipe and welded steel pipe (seamed pipe) two categories. It can be divided into round tube and special-shaped tube according to the sectional shape. The round steel tube is widely used, but there are some special-shaped steel tubes such as square, rectangle, semicircle, hexagon, equilateral triangle and octagon.
