Product Description:

1.Structure of Stainless Steel Coil Cold Rolled 304 With Good Quality


Cold Rolled stainless steel Coil with good quality is one of the raw material of the cold rolled stainless steel Coil

which can be used directly in many places. Stainless Steel (Stainless Steel) is short for acid proof Stainless Steel, resistant to weak corrosive medium such as air, steam, water, or with a Stainless Steel grade.


2.Main Features of Prefabricated Steel Structure High Building Project


Corrosion resistance The vast majority of stainless steel products for corrosion resistant performance is good, like a, 2 kinds of tableware, 

kitchen utensils and appliances, water heaters, water dispensers, etc., some foreign businessmen on corrosion resistance of products 

also do experiment: in NACL aqueous solution heated to boiling, after a period of time the best solution, wash and drying, weight loss, 

to determine the degree of corrosion (note: the product polishing, because of the sand cloth or sandpaper containing Fe, will cause the 

test surface rust spots)

The word "stainless steel" is not merely refers to a pure stainless steel, but said more than one hundred kinds of stainless steel 

industry, the development of each stainless steel has good performance in their specific applications. The key to the success of 

the first is to make clear purpose, and then determine the correct material. Related to architectural construction applications usually 

only six types of steel. They contain 17 ~ 22% chromium, good steel contains nickel. Add molybdenum can further improve the 

atmospheric corrosion resistance, especially containing chloride atmospheric corrosion resistance. Stainless steel often according 

to the state of organization can be divided into: martensite steel, ferritic steel, austenitic steel, austenitic (twophase) - ferrite stainless 

steel and precipitation hardening stainless steel, etc. In addition, according to ingredients can be divided into: chromium stainless 

steel, chromium nickel stainless steel and chromium manganese nitrogen stainless steel, etc.

Q:How can 304 stainless steel and 201 stainless steel be distinguished by magnet?
Magnets can basically distinguish between the two types of stainless steel. Because 201 stainless steel (chromium, stainless steel) in any state can be attracted by magnets; 304 stainless steel (chromium nickel stainless steel) in the annealing state is generally non-magnetic, and after cold processing, some will be magnetic. However, the manganese steel with high manganese content is non-magnetic; the magnetic properties of chromium, nickel and nitrogen stainless steel are more complex: some are non-magnetic, some are magnetic, some are without magnetism and the surface is magnetic. Therefore, although the basic difference between magnet chromium and chromium nickel stainless steel, but can not distinguish between some special properties, but not distinguish the concrete steel.
Q:What kind of plastic surface friction and wear in stainless steel belt is relatively small?
No solid modification of pure plastic on the surface of stainless steel wear is relatively small, such as polyethylene, PTFE and so on.
Q:Stainless steel strap easy to scrape, how to deal with?
Hand tools also pay attention to, recommend the use of hemostatic forceps to surgery, just take a piece of sandpaper, folded after the use of hemostatic clamp tightly, parallel to the original lines do pull sand, sapphire glass is hard, can not consider it, but watch the shell is made of stainless steel, must pay attention to the operation, can not be it is necessary to draw rub, available cover tape. The technical aspect is that all the sand grains must go up all the time, and all of them are in the center of the dial and radiate.
Q:Why does the stainless steel after processing have magnetism?
In addition, 304 stainless steel after cold processing, the structure of the structure will also change to martensite, and the greater the deformation degree of cold work, the more martensitic transformation, the greater the magnetic properties of steel. The stable austenite structure can be recovered by high temperature solution treatment so as to eliminate magnetism.
Q:Stainless steel pan with magnetic or good without magnetic stainless steel pot?
Stainless steel pot without magnetic is good.In fact, stainless steel is magnetic, and the best stainless steel is austenitic stainless steel, and its magnetic is already weak, and basically no magnetic.
Q:Which stainless steel belt has better elasticity?
In stainless steel strips, SUS301 has the best elasticity, and is used for springs, springs, or EH, or spring.
Q:What is the hardness of stainless steel band 3/4?
Hello, 3/4H stainless steel has too many materials, I don't know what kind of material you are talking about 301 and 304 are different. 3013/4H harder. 304 soft. And 201430, etc.... All different
Q:The difference between stainless steel and cold rolled steel strip
It: cold rolled steel strength is very high, but the toughness and weldability is poor, hard, crisp, bright surface
Q:301 stainless steel belt and 304 stainless steel belt, which quality is good?
You can be responsible to tell you, 304 to better stainless steel, the amount of nickel will be on the 304 to more than 301
Q:Is there any magnetism in stainless steel?
Iron and steel are different in terms of carbon content. An iron carbon alloy with a carbon content of less than 2% is a steel, and a carbon content of more than 2% is called iron. Steel is widely used because of its toughness, elasticity and rigidity. Life is exposed to steel, but people call different. For stainless steel, whether or not the magnet is sucked on or not, as long as the quality standards are met, it is stainless steel. Therefore, from the perspective of metallurgy said, no rust said. The main element of stainless steel corrosion resistance is chromium. If the content of chromium is above 10.5%, the steel will not rust. When smelting, the alloy elements added are different, so there is a difference between the magnet and the suction. Stainless steel is usually divided according to the structure of the organization, can be divided into austenite, ferrite, martensite and other major categories.
