201 stainless steel coil

What is 201 stainless steel coil?

The stainless steel products that we see in our lives are not inferior in appearance. But their types are very different. Actually, there are many types of stainless steel.

In fact, stainless steel coil is the base material of stainless steel products. So, if you want to understand the types and differences of stainless steel products, let’s start with understanding a stainless steel coil.

First of all, stainless steel is resistant to weak corrosive media such as air, steam, and water.

Moreover, some acid-resistant steels are resistant to chemical corrosion media, such as steels that are chemically attacked by acids, alkalis, and salts.

In daily life, people regard these two kinds of steel as stainless steel.

What is 201 stainless steel coil?

The nickel content of 201 stainless steel coil is 5%. So its corrosion resistance is close to 304 stainless steel coil.

In addition, 201 stainless steel is the general term for 201 stainless steel and acid-resistant steel.

Types of stainless steel coil?

The difference in their properties is mainly due to the different alloying elements in the steel. In another word, the difference between them is that they contain different proportions of nickel. And this determines that different types of stainless steel have many different properties.

For the very beginning one, the nickel content of 200 stainless steel coils currently on the market is 1%. Therefore, its corrosion resistance is relatively poor.

Moreover, it is much lower than the 304 and 430 stainless steel coil.

So, based on these elements and structure, what are the characteristics of 201stainless steel coil?

Features of stainless steel coil

First of all, let’s see the merits of it.

Advantages

Low cost

The cost of 201 stainless steel is relatively low. Therefore, engineers and architects use it very frequently.

Second, its weight is very light. Therefore, the transportation cost is relatively low.

low cost

Toughness

In many cases, it requires very hard materials to complete some work quickly. Therefore, the good impact resistance of 201 stainless steel coil makes it tough even in cold conditions.

Moreover, compared to 301 stainless steel, its toughness is 30% higher.

Meanwhile, it can also maintain good ductility. Therefore, designers can reduce the weight of products by using 201 stainless steel. Thus, many designers like it.

Resistance

Besides,another advantage of 201 stainless steel is its high corrosion resistance. In this regard, it can easily defeat metal materials such as carbon steel and aluminium.

However, it also has its shortcomings.

Disadvantages of 201 stainless steel coil

Unfortunately, its resilience is high. That means it is prone to bend. Therefore, when this phenomenon occurs, the manufacturer has to compensate for the best parts.

Based on these features, let’s see how people usually use it.

What is 201 stainless steel coil used for?

201 stainless steel coil is a good material in terms of power and appearance. Therefore, people often use it to make outdoor parts.

For example, auto parts, building materials, grills, etc.

In addition, in a relatively large temperature range, the corrosion resistance of 201 stainless steel coil is very good. Therefore, people often use it in restaurant equipment, household appliances, cooking utensils, etc.

Besides, because the content of chromium in 201 is relatively high, its tensile strength and ductility are very good. The most important thing is that it has good thermal and electrical conductivity. Therefore, people often use 201 stainless steel coil at high-temperature occasions.

Next, let’s understand the purpose of 201 stainless steel in detail.

The use of 201 stainless steel in transportation

As we mentioned above, people can use the 201 stainless steel coil as car accessories.

Meanwhile, It can not only maintain the hardness of accessories but also maintain the gloss of accessories.

Both of these aspects satisfy the demand for automotive accessories.

Secondly, its super hard alloy has good impact resistance. Therefore, people also prefer to choose 201 stainless steel coil to make the external parts of the train carriage. Such as the wall panels and bottom beams on the lower edge of the carriage.

In summary, the lightweight, toughness and aesthetics of 201 stainless steel coil make it shine in the stainless steel transportation industry.

Application of 201 stainless steel coil in buildings

In construction, 201 stainless steel also has wide applications.

Sometimes, architects use modular panels to cover high-rise buildings. And people connect these modular panels to the building by components made of 201 stainless steel coil.

Secondly, many of the escalator frames we see in our lives are also made of 201 stainless steel coil.

Moreover, the parts that carry the rollers inside the escalator are also made of 201 stainless steel coil. Even if we can’t see it many times, 201 stainless steel coil still uses its good performance to build a better life for us.

Moreover, in some coastal areas, people will widely use 201 stainless steel coil in construction projects. Meanwhile, this prevents the building from being corroded by seawater, salt, humid air, etc.

Application of 201 stainless steel on highway

Facilities on highways must play their role in the changing environmental factors. So, this requires their materials to be corrosion resistant and strong. By this token, the government often requires the use of 201 stainless steel coil for highway signs and highway guardrails that we often see. Moreover, for other general signs, people will also choose to use 201 stainless steel.

The use of 201 stainless steel coil in other aspects

Due to the high carbon content of 201 stainless steel coil, it has good formality and weldability. People can easily weld 201 stainless steel coil using various welding techniques.

Therefore, this makes 201 stainless steel coil widely used in the exchanges, boiler industry, pharmaceutical, paper making and other industries.

201 stainless steel coil vs 304 stainless steel coil

First of all, let’s take a look at what is 304 stainless steel.

What is 304 stainless steel coil?

The important elements in 304 stainless steel are Ni and Cr. Moreover, its Ni content is greater than 8%, and its Cr content is greater than 18%.

Secondly, it is recognized as a green material. Therefore, in medical treatment, people will use 304 stainless steel. For example, people use 304 stainless steel to make some parts that can be implanted in the human body.

Let’s take a look at the difference between them.

Different element content

First of all, 201 stainless steel is high-manganese stainless steel, which is harder than 304 grade. Moreover, its carbon and nickel content is much higher than 304 grade.

Secondly, 201 stainless steel has a high manganese content. Therefore, the surface is very dark. Meanwhile, it is easy to rust with high manganese content.

However, the 304 stainless steel vacuum flask contains more chromium, and the surface is matte and does not rust.

The difference in these contents makes their performance different.

304 grade has strong corrosion resistance

There is more Cr in 304 stainless steel. Therefore, its corrosion resistance is better.

In experiments, people find that even nitric acid with a low boiling point cannot corrode 304 stainless steel.

Therefore, compared to 304 stainless steel, 201grade is more prone to rust.

By this token, some occasions require strong corrosion-resistance, people generally choose 304grade.

Punching resistance

The impact resistance of 304 stainless steel is also better than that of 201. Therefore, in a complex environment, people generally use 304 stainless steel.

However, in situations where the requirements for stamping resistance and corrosion are not so strict, people will choose 201 grade.

Toughness

201-grade steel is harder than 304. Therefore, it is easier to crack. Therefore, 304 stainless steel has better humanity and fatigue resistance than 201.

Application

201grade has a wide range of applications:

  1. Electrical appliances
  2. Auto parts
  3. Industrial products
  4. Kitchen utensils and cookware
  5. Door
  6. Foodservice equipment
  7. Tram
  8. Sink

And, people can deal with it in many ways:

  1. Stamping
  2. Forming
  3. Bend
  4. Cutting
  5. Welding alloy
  6. Cold working (This can increase the hardness and strength of 201 grade)

Besides, because of the different content of carbon, manganese, nitrogen and nickel, 201 can provide many variants.

So, in each application, these variants have their own characteristics.

Look at the difference from the catering industry

201 stainless steel coil contains manganese. Moreover, its water resistance is weaker than that of 201 and 304. Therefore, long-term use of 201 stainless steel coil products for drinking water will cause loss of appetite, vomiting, diarrhoea, gastrointestinal diseases, stool disorders and other diseases.

However, 304-grade steel has a layer of Cr oxide on the surface. It can protect the steel from rust. Therefore, it can achieve the effect of healthy drinking.

By this token, stainless steel vacuum flasks usually use 304 stainless steel.

However, there is no obvious difference in appearance between 201 stainless steel thermos and 304 stainless steel thermos.

Therefore, it is recommended that people pay attention to its material when buying stainless steel thermos.

Price

Because 201 grade contains more manganese, nitrogen and nickel than 304 grade, the combination of these elements reduces its cost.

Moreover, this combination improves its mechanical strength.

Thus, 201 grade can harden faster than 304 grade.

However, the combination of these elements reduces the corrosion resistance and oxidation resistance of 201 grade.

Therefore, 304 grade is more expensive.

Conclusion

Stainless steel is resistant to weak corrosive media such as air, steam, and water. Moreover, some acid-resistant steels are resistant to chemical corrosion media, such as acids, alkalies, and salts,etc.

201 stainless steel is a type of stainless steel. Its nickel content is 5%, so its corrosion resistance is very good.

Meanwhile, 201 stainless steel coil is the base material of its products.

Due to its nickel content and the properties of other alloys, it has good performance in corrosion resistance, weldability, hardness and appearance. Moreover, cost and transportation cost are very low.

Therefore, it has a wide range of uses in various industries such as automobile accessories, buildings, road signs, and pharmaceuticals and switches.

Although it is often difficult to see the internal structure of these products, 201 stainless steel still has a good impact on our lives due to its good performance.

For the difference between 201 grade and 304 grade, we can get to know it from the following aspects:

  1. carbon and nickel content of 201 grade is also much higher than 304 grade. While 304 stainless steel contains more chromium.
  2. 304 grade has better corrosion resistance, impact resistance and toughness than 201 grade. However, the application of 201grade is wider.
  3. In terms of price, the price of 201 is lower than that of 304.
