Product Description:

Stainless Steel Coil Cold Rolled 304 With Good Quality

 

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

1) Weld-ability: The purpose of the different requirement for welding performance are 

different.1 Kind of tableware generally do not require the performance of welding, even

including some pot class enterprise. But the vast majority of products all need raw

materials welding performance is good, like the 2 kinds of tableware, thermos flask, steel

pipes, water heaters, water dispensers, etc.

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 (two-phase) - 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.


Austenitic, ferritic duplex stainless steel The advantages of both austenitic and ferritic 

stainless steel, and has the superplasticity. Austenite and ferrite The title Each accounts 

for about half of the stainless steel. In the case of contain low C, Cr content was 18% ~

18%, Ni content at 3% ~ 3%. Some steel containing Mo, Cu, Si, Nb, Ti, N and other

 alloying elements. This kind of steel both austenite and ferrite stainless steel, the 

characteristics of compared with ferrite, plasticity and toughness is higher, no room 

temperature brittleness, intergranular corrosion resistance and welding performance were 

significantly increased, while maintaining a ferritic stainless steel of 475 ℃ brittleness and 

high thermal conductivity, has the characteristics of superplasticity. Compared with 

austenitic stainless steel, high strength and resistance to intergranular corrosion and 

resistance to chloride stress corrosion is improved obviously. Duplex stainless steel has 

excellent resistance to pitting corrosion performance, is also a kind of nickel and stainless 

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?
On the local case or watch strap deep scratches, repair before the need to do local processing, look at the location, such as the shell side case, there may even use the fine small file, more is the use of stone, then under the magnifying glass, carefully remove deep scratches and boring flat, deep scratches in the first, to focus on the local stone grind. This needs to be under a magnifying glass, the purpose is to scratch evenly polished, when basic scratches are going to grind, choose suitable size to sandpaper, grinding along the original sand drawing lines, so the lines are usually on the dial radially, and this is a carefully, to a little, the effect will be good to rub out the realistic. It is recommended that the sand paper be used in jewelry industry, preferably imported, such as German warrior brand water sandpaper.
Q:Why does stainless steels carry magnetism?
If you go to the molten steel and high chromium nickel austenitic steel, tempered magnet is not stainless steel. If the molten steel in the main alloy elements is chromium, iron and carbon and a small amount of nickel (or without nickel), tempered steel is a magnet on the stainless steel, also called ferritic stainless steel martensitic stainless steel or austenitic stainless steel. In addition to the magnet is not on, ferrite, martensite stainless steel are magnetic. The nickel element in the reserves in the world is very few, the price is more expensive, therefore, high nickel content in stainless steel on the market price is higher, and the magnet suction is not at present because of austenitic stainless steel for stainless steel in the proportion is still great, so that people have a misconception of all stainless steel are non-magnetic.
Q:Why does the stainless steel after processing have magnetism?
The austenite is non-magnetic or weakly magnetic, and martensite or ferrite is magnetic, a tripod of stainless steel processing in processing time due to melting segregation or improper heat treatment, will cause a small amount of martensite Austenitic 304 stainless steel body or ferrite. In this way, 304 stainless steel will have a weak magnetic.
Q:Does the 301 stainless steel band contain magnetism?
No magnetism. Related to stainless steel information, you can pay attention to "I want stainless steel" website, I usually look at it above, registered members can also see relevant member information. You can pay attention to it!
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: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?
No absolute, which quality is good, the key depends on what kind of product is suitable. Under normal circumstances, the requirements of hardness, elasticity, as elastic components, structural parts of the 301 materials used more, can also achieve a higher hardness of about HV600. Product positioning higher, 304 materials can be appropriately selected, the highest hardness can reach about HV500.
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.
Q:What type of stainless steel is magnetic stainless steel?
1, 420- type "cutting class" martensitic steel, similar to Brandt's first high chromium stainless steel this. Also used in surgical knives, which can be made very bright.2 model 430- ferritic stainless steel for decorative purposes, such as automotive accessories. Good formability, but poor temperature resistance and corrosion resistance.3, 440- type high strength cutting tool steel, carbon is slightly higher, after appropriate heat treatment to obtain a higher yield strength and hardness can reach 58HRC, which belongs to the most hard stainless steel column. The most common example is razor blades".
