How to select stainless steel coils?

Determining the type

stainless steel coils and many kinds, different kinds of stainless steel coils have different structural characteristics, for example, stainless steel coils if you want to be magnetic, it will be more hard, and the hardness is high, the corresponding elasticity will be higher. To make such a stainless steel strip, 201 and 304 are not possible, only 301 can achieve such an effect.

Observe the appearance

The quality of a stainless steel coil can be felt in its appearance. A good stainless steel coil is bright, smooth and of medium thickness. Don't pick the kind of stainless steel coil that feels like it has obvious surface strains and is rough - it is better to choose a manufacturer with a high reputation to avoid quality problems.

There are many different types of stainless steel coils. In order to enhance the corrosion resistance, mechanical strength, ductility and other properties of steel, stainless steel in addition to a high content of chromium, but also add nickel, molybdenum, manganese and other alloying elements. Different alloy ratios make up different types of stainless steel. It is therefore important to understand the characteristics of each stainless steel coil.

How long do stainless steel coils last?

 

The use of stainless steel coils depends on its length and thickness, and different materials of stainless steel also have different service lives. At the same time, stainless steel is resistant to corrosion, and its service life will be very long, but the specific service life depends on the degree of maintenance. It is worth noting that another advantage of stainless steel is that waste is also more valuable. When calculating the cost, you can subtract the estimated cost of selling waste. This is also considered a cost saving. Therefore, stainless steel is a long-life and environmentally friendly product.

 

Factors affecting the working life of stainless steel.

 

Cleanliness

The chemical composition and surface finish of stainless steel coils are closely related to the manufacturing environment and cleanliness. As long as the stainless steel surface and the surrounding working environment are cleaned up in time, the surface quality of the stainless steel coils can be indirectly improved, thereby prolonging its use. life.

 

Rusty

Although stainless steel coils have strong corrosion resistance, this does not mean that they will not rust. Whether stainless steel rusts directly affect its use. There are many reasons for the rust of stainless steel. For example, the dust containing other metal elements is accumulated on the surface of the stainless steel. Electrochemical corrosion will occur in a humid environment for a long time. In addition, if organic juice is attached to the surface of stainless steel or placed in polluted air, it will be easily corroded and rust will occur.

 

When using stainless steel coils, we need to maintain them regularly, and we cannot clean them with tools that wear down the surface, such as steel wire balls. Keep the stainless steel coil environment dry. In this way, the stainless steel coil will not be corroded and appear flaws, and it can maintain a beautiful image.

 

Features of cold rolled stainless steel

 

Cold-rolled stainless steel is processed from hot-rolled plates at room temperature. Although the rolling process will heat up the steel plate, it is still called cold-rolled. Steel grades that are resistant to weak corrosive media such as air, steam, water, or have rust resistance are called stainless steel, and there are many manufacturing methods. Cold rolled steel is widely used in general structural parts and stamping parts in construction machinery, transportation machinery, construction machinery, hoisting machinery, agricultural machinery and light industry and civil industries. The thickness of the cold-rolled steel plate is more accurate, and the surface is smooth and beautiful, and it also has various superior mechanical properties, especially in terms of processing performance.

Have you learned more about Stainless Stell Coil from the above information?Stainless Steel Coil is a product with a wide range of applications. Jiangsu C.J.M.

At present, the stainless steel commonly used in kitchen equipment mainly includes 201 and 304. 201 stainless steel is cost-effective, cheap, but easy to rust; 304 stainless steel is the most widely used stainless steel material, not easy to rust, good quality, the price is also higher than 204.

There is almost no difference between 201 stainless steel plate and 304 stainless steel plate, which can hardly be distinguished by naked eyes. Here are some methods to distinguish them.

 

1. Specification: commonly used stainless steel plate is divided into 201 and 304 two models, the actual composition is different, 304 good quality, but the price is expensive, 201 poor. 304 is imported stainless steel plate, 201 is domestic stainless-steel plate.

 

2. The composition of 201 is 17cr-4.5ni-6mn-n, which is the substitute of 301 steel. It has magnetism after cold working and is used in railway vehicles.

 

3. The composition of 304 is 18cr-9ni, which is the most widely used stainless steel and heat-resistant steel. For food production equipment, chemical equipment, nuclear power, etc.

 

4. 201 stainless steel plate has high manganese content, bright surface with dark brightness, high manganese content is easy to rust, manganese is also harmful to human nervous system, so 201 stainless steel plate is not suitable for food grade equipment. 304 contains more chromium, the surface is matte, not rusty. The two are compared together.

The most important thing is that the corrosion resistance is different. The corrosion resistance of 201 is very poor, so the price is much cheaper. Because 201 has low nickel content, the price is lower than 304, so the corrosion resistance is not as good as 304. And 304 stainless steel safety belongs to the edible grade material, at present, the edible grade stainless steel is 304 stainless steel plate and above.

 

5. The difference between 201 and 304 is the nickel content. And the price of 304 is more expensive now, but 304 can at least guarantee that it will not rust in the process of use. (stainless steel solution can be used for experiment)

 

6. The reason why stainless steel is not easy to rust is that chromium rich oxide formed on the surface of steel body can protect the steel body

 

7. Different composition (mainly from carbon, manganese, nickel, chromium to distinguish 201 and 304 stainless steel)

 

Steel grade carbon (c) silicon (SI) manganese (MN) phosphorus (P) sulfur (s) chromium (CR) nickel (Ni) molybdenum (MO) copper (Cu)

 

AISI(304) ≤0.08 ≤1.00 ≤2.00 ≤0.045 ≤0.03 18-20 8-10

 

AISI(201) ≤0.15 ≤1.00 5.5-7.5 ≤0.05 ≤0.03 16-18 3.5-5.5

 

Therefore, 304 stainless steel is the best material for the production of kitchen equipment. However, many unscrupulous businesses in the market now use 201 stainless steel to fill 304 stainless steel, which is difficult to distinguish when accepting. Therefore, when purchasing stainless steel kitchenware and kitchen equipment, first of all, do not choose brands lower than the industry price.
