Definition of stainless steel(Adopted form Wikipedia)Wholesales Stainless Steel Pipe 201 tube 1mm thick

In metallurgy, stainless steel, also known as inox steel or inox from French "inoxydable",

is defined as a steelalloy with a minimum of 10.5% to 11% chromium content by mass.

Stainless steel does not readily corroderust or stain with water as ordinary steel does,

but despite the name it is not fully stain-proof, most notably under low oxygen, high salinity,

or poor circulation environments. It is also called corrosion-resistant steel or CRES

when the alloy type and grade are not detailed, particularly in the aviation industry.

There are different grades and surface finishes of stainless steel to suit the environment

the alloy must endure. Stainless steel is used where both the properties of steel

and resistance to corrosion are required.

Q:How can I clean the stainless steel tube?
Stubborn or burned stains, can be mixed with baking soda and water, wipe with a soft cloth.
Q:Classification, advantages and disadvantages of stainless steel welding
The utility model has the advantages of universal use and easy operation, and is mainly regulated by people, and the welding seam material is an electric welding strip. Manual welding can weld almost all of the material, even outdoors, so it has good adaptability and is usually powered by direct current.Welding, either titanium type electrode, can also be sealed. The titanium electrode is easy to weld, the welding seam is beautiful, and the welding slag is easy to remove. But the drawback is that if you do not use it for a long time, you must bake it again to prevent moisture accumulation.
Q:Stainless steel why are rust?
Stainless steel surface adhesion of organic juice (such as vegetables, soup, sputum), oxygen in the water under the circumstances, a long time, organic acid, organic acid on the surface of metal corrosion.
Q:How can the stainless steel tube eliminate stress?
Or artificial stress, method: stresses both ends of the steel pipe fixed by the mold, through high-frequency shocks, so that the internal stress relief of the steel pipe
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
Plastic pipe, plastic pipe, also known as plastic composite pipe, with steel pipes for the matrix, by spraying, rolling, leaching, absorption process in steel tube (bottom tube) steel plastic composite pipe internal surface is welded with a layer of plastic coating or plastic anti-corrosion layer on the inner surface and the outer surface of the weld. The plastic pipe has excellent corrosion resistance and small friction resistance. Delivery of epoxy resin coated steel pipe is suitable for water, water, water, oil, gas and other medium, PVC plastic pipe for drainage, water, oil, gas and other media delivery.
Q:Advantages and disadvantages of PPR lined stainless steel pipe and PPR aluminium plastic pipe
PPR lined stainless steel tubeAdvantage:Stainless steel lining pipe, high temperature resistance, can transport hot water, boiling water, steam, and safety and health. The installation of stainless steel tube after the whole bearing pipe resistance, impact resistance, corrosion resistance and other properties to strengthen and enhance the original tube, not only can be used for civilian water and gas, can also be used for fluid transportation industry.shortcomingOnce the processing is not well controlled, it is easy to cause stainless steel and PPR delamination.
Q:Is galvanized steel pipe stainless steel pipe?
Not galvanized pipe, but the surface of the welded pipe galvanized zinc rust protection. The stainless steel pipe is welded by stainless steel band, or made of stainless steel bar punched (seamless pipe). And the two prices are very different
Q:SA-179 what kind of material is steel pipe?
Compared withsteel and roundsteelinsolid, flexural torsional strength in the same time, the weight is light, is a kind of economic section steel, widely used in the manufacture of structural parts and mechanical parts, such as the oil pipe, automobile transmission shaft, the bicycle frame and steel construction with scaffold with steel pipe manufacturing ring parts can be improved the utilization rate of materials, simplify the manufacturing process, material saving and working hours, has been widely used to manufacture steel tube.
Q:What's the difference between cold drawn steel tube and hot rolled steel tube?
Hot rolling is relative to cold rolling, cold rolling is performed under recrystallization temperature, while hot rolling is rolling above recrystallization temperature.Seamless steel pipe, hot-rolled and cold-rolled (DIAL) seamless steel pipe two categories.Hot rolled steel tubes are divided into ordinary steel tubes, low and medium pressure boiler tubes, high pressure boiler tubes, alloy steel pipes, stainless steel pipes, oil cracking pipes, geological steel pipes and other steel pipes, etc..
