Definition of stainless steel(Adopted form Wikipedia)

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.

No.2B

The surface brightness and flatness of no2B is better than no2D. 

then through a special surface treatment to improve its mechanical properties,

No2B could nearly satisfy comprehensive uses.

Polished with abrasive belt of git#100-#200, have better brightness with 

discontinuous coarse stria, used as inner and external ornaments for building, 

electrical appliances and kitchen utensils etc.

No.4

Polished with abrasive belt of grit #150-#180,have better brightness

 with discontinuous coarse stria, but thinner than No3, are used as bathtub

Q:Stainless steel pipes can not be less than the amount of chromium
The chromium content of stainless steel is generally not less than said first why stainless steel tube is not easy to rust 12%-304 stainless steel tube, then why stainless steel will rust stainless steel is not easy to have a great relationship with the composition of stainless steel rust. In addition to iron, stainless steel contains chromium, nickel, aluminum, silicon and so on.
Q:Why does the 304 stainless steel pipe leak?
Chloride poisoning. Why chlorine is found in tap water is not explained here.
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:In stainless steel tubes, why are there some SS in the back and some standard L, such as 316L and 316SS? What's the difference?
There is no essential difference between 316SS and 316L, the same as austenitic stainless steel, and SS means stainless steel.316SS and 316L stainless steels are made of Mo stainless steel. The total performance of this steel is better than that of 310 and 304 stainless steel. Under high temperature, 316 stainless steel is widely used when the concentration of sulfuric acid is below 15% and higher than 85%. 316 stainless steel also has good chloride corrosion resistance, so it is often used in marine environments.
Q:Stainless steel and stainless steel pipe inside and outside polishing off, what is the difference?
The inside and outside polishing tubes are polished by the surface of the polished material, and they look like bright ones, just like the mirror surface. Mainly used in viscous liquid and gas moving equipment, such as printing and dyeing, pulp and other industries
Q:Stainless steel pipe drilling?
General requirements for processing stainless steel workpiece hole smooth, less burr, white technology generally choose high-quality grinding drill, on the market are mostly black rolling process, the main difference between full grinding and rolling process is drilling with the drill chuck supporting the overall use of small amplitude and hole grinding, less burr, the accuracy is high especially, when batch processing efficiency.
Q:Where is the difference between seamles steel pipe and welded pipe?
1., the appearance of seamless steel pipe and welded pipe difference in the welded pipe wall welded tendons, and seamless No.2. seamless pipe pressure is higher, welded pipe is generally in 10 or so MPa, now welded pipe to do seamless processing.3. seamless steel tube is formed in the rolling process. 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:What is the difference between stainless steel tube 304L and 304N?
The lower carbon content minimizes the precipitation of carbides in the heat affected zone near the weld, while the precipitation of the carbides may lead to intergranular corrosion in stainless steels in certain environments.
Q:Stainless steel tube, also known as why tube
It can be divided into round tube and special-shaped tube according to the cross sectional shapeThe special-shaped tube has a rectangular tube, a rhombus tube, an elliptical tube, six square tubes, eight square tubes, various cross section asymmetric pipes, etc.
Q:Stainless steel why are rust?
In polluted air (such as atmosphere containing large amounts of sulfides, oxides of carbon and nitrogen oxides), condensate is formed when sulfuric acid, nitric acid, and acetic acid are subjected to condensation, resulting in chemical corrosion.
