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 

steel.

Q:How can 304 stainless steel and 201 stainless steel be distinguished by magnet?
The steel of the oxide layer was removed, put a drop of water, rub rub after copper sulfate, such as discoloration, usually stainless steel; such as purple red, nonmagnetic high manganese steel, magnetic for ordinary steel or low-alloy steel.
Q:What is the hardness of stainless steel band 3/4?
304 stainless steel is the United States materials and Testing Association (ASTM) named SUS 304 stainless steel brand abbreviation. 304 stainless steel, 1Cr18Ni9., is a widely used austenitic stainless steel.
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:Stainless steel pan with magnetic or good without magnetic stainless steel pot?
Without magnetic material if it is of course good 316304 of the material, if it is 201202 or easy to rust, the magnetic material is 443 than 304, this is due to their corrosion resistance, high heat conduction rate of 443, in the province of gas when cooking, can also be used with magnetic pot do the electromagnetic oven, 443 material pot is cheaper than 304, considering the magnetic well
Q:Do you have stainless steel with magnetic?
The chromium content of ferritic stainless steel (400 Series) is 15%~30%, and has the structure of body centered cubic crystal. This kind of steel does not contain nickel, sometimes also contain a small amount of Mo, Ti, Nb and other elements, this kind of steel has high heat conductivity, low expansion coefficient, good oxidation resistance and anti stress excellent characteristics of stress corrosion, used formanufacturingthecorrosionresistanceofthe atmosphere, water vapor, waterandoxidizing parts.
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:What are the main stainless steel belt used in the industry and products?
This is the fastest growing area of stainless steel applications. The use of high strength stainless steel car body structure can greatly reduce the weight of the car, and enhance the strength of the body structure, using stainless steel as vehicle panels and decorative parts, can reduce maintenance costs.The problem of water pollution during storage and transportation has been paid more and more attention. A great deal of practice has proved that stainless steel is the best choice for water preparation, storage, transportation, purification, regeneration, desalination and other water industry. The advantages are: corrosion resistance, earthquake resistance, water saving, sanitation (no rust and copper green), light weight (reduced 1/3), Shao Weixiu, long life (40 years service), life cycle cost (LCC) is low, Recyclable using green materials.
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:Which material is better, stainless steel or belt?
Summer is the best with a stainless steel belt, the belt in the summer after the sweat corrosion, there will be an unpleasant smell, easily broken; stainless steel material is relatively good, generally not bad, summer with sweat also nothing, no taste. I hope my answer will be helpful to you!
Q:What type of stainless steel is magnetic stainless steel?
Model with magnetic stainless steel: martensite or ferrite: such as 430, 420, 410 and so on, is magnetic.
