Q:Is food grade stainless steel GB9684 304?
304 stainless steel is a very common stainless steel, the industry is also called 18/8 stainless steel. It is better than the corrosion resistance of 430 stainless steel, high temperature corrosion resistance, good processing performance, so it is widely used in industrial and medical furniture industry and the food industry, for example, some high-grade stainless steel tableware, bathroom and kitchen utensils. 304 is a versatile stainless steel which is widely used in the manufacture of equipment and parts requiring good overall performance (corrosion resistance and formability). In order to maintain the inherent corrosion resistance of stainless steel, steel must contain more than 17% chromium, more than 8% of the nickel content. General 304 stainless steel is not food grade, specially processed is food grade.
Q:Can magnets attract stainless steel tubes?
Stainless steel is becoming more and more popular because of its beautiful appearance, corrosion resistance and not easy to damage. More and more pots, city sculpture, architecture, decoration room etc. the use of stainless steel, stainless steel on discrimination but people do not know, some customers buy stainless steel kitchenware, stainless steel utensils with magnets in to try to try. It is stainless steel that attracts the magnet, but stainless steel can not be sucked. It seems that there is a misunderstanding about stainless steel.
Q:What are the categories of stainless steel pipes with acid and alkali resistance?
Austenitic stainless steel is the stainless steel with austenite structure at normal temperature. When the steel containing Cr is about 18%, Ni, 8%~25% and C is about 0.1%, it has a stable austenite structure. Austenitic chromium nickel stainless steel includes the famous 18Cr-8Ni steel, and on this basis, increasing the content of Cr, Ni, and adding Mo, Cu, Si, Nb, Ti and other elements developed by the high Cr-Ni series steel. Non magnetic austenitic stainless steel with high toughness and plasticity, but the intensity is low, not through the phase change to strengthen, can only be strengthened by cold working, such as adding S, Ca, Se, Te and other elements, it has good machinability. Good comprehensive performance, corrosion resistant variety of media.To prevent intergranular corrosion, this kind of stainless steel is usually low carbon or ultra low carbon.
Q:What factory uses industrial stainless steel tube to be more?
For equipment manufacturing and maintenance, etc., the annual consumption of stainless steel pipe more than 20000 tons. Such industries mainly use sanitary or antibacterial grade stainless steel tube.
Q:Difference between stainless steel and steel pipe
2. welded steel pipe for different welding process and divided into the furnace pipe welding (ERW) pipe and automatic arc welding, because of the different forms of welding seam welded pipe and spiral welded pipe is divided into two kinds, end its shape is divided into circular welded and shaped (square, flat) pipe.The welded pipe is rolled into the steel tubular to sew or spiral seam welded in the manufacturing method, and is divided into low pressure fluid delivery with welded steel pipe, spiral welded steel pipe, welded steel pipe, welded pipe roll etc.. Seamless steel pipe can be used in various industries, such as liquid, pneumatic, pipeline and gas pipeline. Welding pipes can be used in water pipelines, gas pipelines, heating pipes, electrical appliances, pipelines and so on.
Q:Stainless steel works. What saw can be sawed off?
Hand hacksaw can, but a bit slow. It's faster with a toothed saw and a grinder.
Q:304 stainless steel will rust it?
Stainless steel is a very thin layer formed on the surface and the stability of the fine solid chromium rich oxide film (protective film), to prevent the infiltration of oxygen atoms, to oxidation, and the ability to obtain anti-corrosion. Once there are some reasons, this film was constantly destroyed, air or liquid oxygen atoms will continue to infiltrate or metal atoms of iron to keep out from the loose formation of iron oxide, the metal surface will be continuously corroded.
Q:How about stainless steel 2520 and 316?
2520 stainless steel (310S) austenitic chromium nickel stainless steel has good oxidation resistance, corrosion resistance, because of higher content of chromium and nickel content, which has high temperature creep strength, can continuously work under high temperature, good heat resistance. For Ni (Ni), chromium (Cr) content is high, with good oxidation resistance, corrosion resistance, acid and salt, high temperature performance, high temperature resistant steel dedicated to the manufacture of electric furnace tube and so on, increase the amount of carbon austenitic stainless steel, due to the solid solution strengthening effect to the strength improved, chemical composition characteristics of austenitic stainless steel is chrome, nickel based addition of molybdenum and tungsten, niobium and titanium elements, as its face centered cubic structure, and strength and high creep strength at high temperature.
Q:Why can stainless steel pipes be welded by argon arc welding?
Argon protection can isolate the harmful effects of oxygen, nitrogen and hydrogen on the arc and molten pool in the air, and reduce the burning loss of alloy elements, so as to obtain compact, no spatter and high quality welded joints;
Q:How can I clean the stainless steel tube?
Grease can be applied to soft cloth to dissolve alcohol. It is important to rinse off the alcohol and dry it so that it has a shiny metal.
