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.

Characteristics and application                                                                        

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.

No.3

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

 buildings inner and external ornaments electrical appliances kitchen

 utensils and food processing equipment etc.

Polished with abrasive belt of grit #150-#320 on the NO.4 finish and has 

continuous streaks, mainly used as buildings ornaments elevators, 

door of building, frontal plate etc.

Q:Classification, advantages and disadvantages of stainless steel welding
The arc is produced between the tungsten welding wire and the workpiece, so the protection gas is pure argon and the welding wire is not charged, so it can be sent by hand or by machine. Then it is whether to use direct current or alternating current, depending on the welding material.
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:What's the easiest way to distinguish between stainless steel 202 and 304?
304 stainless steel performance is better than 202 stainless steel, the price is more expensive than 202 stainless steel.
Q:How can the stainless steel tube eliminate stress?
After heating 500 degrees, placed at room temperature or placed at room temperature for more than 2 years
Q:What kind of welding machine is used for welding thin stainless steel plate and stainless steel square tube?
1 mm thick enough, basically argon arc welding machine can, 0.2 thick stainless steel plate welding is not good ah, how have three or four points it can be positive or negative, only a few joints only, mainly to see the technology myself you, not what, the polishing wheel is on the line let's do it, you can buy a good quality of argon arc welding machine, the high price of the arc is stable
Q:What's the difference between stainless steel pipe or stainless steel composite pipe?
The stainless steel composite pipe is iron pipe. The outside is plated with stainless steel. It is heavy, but it is easy to rust for a long time,
Q:304 stainless steel, welded to seamless difference in what place?
The grain size of the metal is related to the temperature of heat treatment and the time of keeping the same temperature. The welded stainless steel pipe and seamless stainless steel tube as the annealed grain size. If the minimum tube cold treatment, the grain size of the weld metal is smaller than the grain size, welding or grain size is the same.
Q:What's the difference between stainless steel 304 and stainless steel 202?
Different chemical composition. 304 of the nickel is much higher than 202.
Q:What are the specifications of stainless steel decorative pipes?
Decorative tubes, then more specifications. Our factory has the smallest 9.5MM, the largest to see how big you can, directly with the industrial pipe to polish it
Q:What is the difference between stainless steel tube 304L and 304N?
304L is a variety of 304 stainless steel with low carbon content, used for occasions where welding is required.
