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

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.

Heat resistant performance Heat resistant performance refers to the high temperature 

stainless steel can still maintain its excellent physical and mechanical properties. Carbon: 

the influence of carbon in austenitic stainless steel is formed strong and steady. Set the 

austenitic austenitic area and expand elements. Carbon formation of austenite is about 30

 times that of the nickel, the ability of carbon is a kind of gap elements, through the solid 

solution strengthening can significantly increase the strength of the austenitic stainless 

steel. Carbon austenitic stainless steel can be improved in high concentration chloride 

(e.g., 42% MgCl2 boiling solution) in the performance of the resistance to stress corrosion. 

But, in the austenitic stainless steel, carbon is often seen as the harmful elements, this is 

mainly due to the corrosion of stainless steel used in some conditions, such as welding or 

heating by 450 ~ 850 ℃), carbon steel with chromium in forming high chromium Cr23C6 

type carbon compounds which can lead to local chromium depletion, make steel corrosion 

resistance especially resistant to intergranular corrosion performance degradation. So. 

Since the 60 s of the development of new Cr-Ni austenitic stainless steel is mostly carbon 

content less than 0.03% or 0.02% of the ultra-low carbon type.

Ferritic stainless steel Chromium containing 15% ~ 30%. Its corrosion resistance, 

toughness and weldability with chromium content increases with the increase of chloride 

stress corrosion resistance is superior to other types of stainless steel, fall into this 

category of Crl7, Cr17Mo2Ti, Cr25, Cr25Mo3Ti, Cr28, etc. Ferritic stainless steel because 

of the high chromium content, corrosion resistance and oxidation resistance are relatively 

good, but the mechanical properties and process performance is poorer, more used to 

stress less acid structure and steel used as antioxidant. This kind of steel to withstand 

atmosphere, nitric acid and corrosion of the brine solution, and has good high temperature 

oxidation resistance, low thermal expansion coefficient, etc, used in nitric acid and food 

factory equipment, also can make work under high temperature parts, such as gas turbine 

parts, 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

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:What is the difference between stainless steel coil and stainless steel plate?
One is a coil and the other is a strip.
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:Do you have stainless steel with magnetic?
Austenitic stainless steel is the stainless steel with austenite structure at normal temperature. When the steel containing Cr is about 18%, Ni, 8%~10% 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.
Q:Which material is better, stainless steel or belt?
Speaking, of course, the material is stainless steel, stainless steel is not easy to change color, corrosion resistance, etc., and the cortex is not resistant to corrosion, and sometimes easy to fade. This should be based on their preferences, as well as personality and usual dress up, stainless steel for formal dress, such as shirts, suits, leather, suitable for casual wear
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 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 narrow band, what are the spare rolls and side bands?
Sideband: roll out of the steel plant, has a certain width, when customers order the specified width, need to do a movement, to meet customer demand, but the width of the collocation, not satisfactory, will the remaining material (not in a material), such as roll material is 1185mm wide, to the customer is 60mm wide, the rest of the material is, the price is the lowest.
Q:How can 304 stainless steel and 201 stainless steel be distinguished by magnet?
After pickling of stainless steel, surface color silver finish: chromium nickel stainless steel color white jade is white; chromium stainless steel slightly weak light Ze; CrMnN Stainless steel and chromium nickel stainless steel similar color is slightly lighter. The surface color: stainless steel pickling chrome nickel steel is brown and white, brown and black chromium, chromium manganese nitrogen is black (the three color refers to the oxidation of the heavier color). Cold rolled unannealed chromium nickel stainless steel, silver reflective surface.
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.SUS301 is the highest hardness, can be HV590 degrees, is less than SUS304. If you want to use the materials required materials SUS301 HV480.
