What is the stainless steel in grade 201? The question and answers

What is the stainless steel in grade 201? The question and answers.

Stainless steel is a very popular material nowadays. In there,  Stainless stee in grade 201  is one of the most popular stainless steel on the market. There is a lot of information around this type of stainless steel. Here are 10 most common questions about stainless steel in grade. Hope you will find useful information for yourself.

What is the stainless steel in grade 201?

Stainless steel in grade 201 is a type of stainless steel in about 200 types – austenite (stainless steel is classified into the main types of austenitic, ferritic, austenitic-ferritic (Duplex), Martensitic, Precipitation Hardening). The stainless steel in garde 201has higher manganese and nitrogen content and lessen the nickel content. Because the composition of different components also make the stainless steel in grade 201 characteristics compared to other types of stainless steel, there are superior advantages and also more defects. In general, the stainless steel in grade 201 is cheaper than another popular stainless steel- the stainless steel in grade 304, but the advantages of the stainless steel in grade 201 are not as good as the stainless steel in grade 304

What are the characteristics of the stainless steel in grade 201?

Like the other stainless steel , the stainless steel  in grade 201 also has durability, corrosion resistance, heat resistance as well as maintenance, hygiene and aesthetic advantages. However, because of the different chemical elements, the level of these advantages is also slightly different from the other stainless steel. Typically, the Nikel component in the stainless steel in grade 201 is lower than the stainless steel in grade 304 so the stainless steel in grade 201 will have more hardness, more susceptible to corrosion than the stainless steel in grade 304 and The surface is not as shiny as the  stainless in grade 304. However, the durability of the stainless steel in grade 201 is quite high. This is one of the strengths that the stainless steel in grade 201 brings.

The Stainless steel in grade 201 is an easy-to-work material because of its good shape. Machining methods such as cutting or welding can be done on this type of stainless steel.

The stainless steel in grade 201 is non-magnetic, is widely applied to products that enhance the resistance of words. But for products that need magnetism,, The stainless steel in grade 201  is necessary to add a layer of the stainless steel in grade 410 or 430 in the outer layer.

Is the stainless steel in grade 201 rusty?

Because the stainless steel in grade 201 has a higher manganese structure and lower Nikel ratio, although the general feature of the stainless steel is corrosion resistant, The stainless steel in grade 201 is still more susceptible to rust than the stainless steel in grade 304 and 316. Hence,The price of the stainless steel in grade 201 is relatively cheaper. However, if compared with non-stainless steel materials (plastic, steel, aluminum …), the stainless steel in grade 201  is considered a relatively good choice for products that need durability and antioxidant.

What is the melting temperature of the stainless steel in grade 201?

Stainless steel is a heat-resistant material. In there, The stainless steel in grade 201 has a peak temperature for melting at about 1400 – 1450 ° C, equivalent to the melting temperature of the stainless steel in grade 304 but lower than other stainless steel

Does the stainless steel in grade 201 have electrical conductivity?

This is a question that has received a lot of attention and questions. The answer is yes but not significant. Unlike 100% conductive copper metal or good conductive metals such as gold, silver, iron, aluminum … The stainless steel in grade 201 has an extremely low electrical conductivity. Therefore, stainless steel does not belong to the materials used for electrical conductivity.

Is the stainless steel in grade 201 toxic?

One of the advantages that makes stainless steel a preferred material is that they are extremely safe for human health and environmentally friendly. The Stainless steel in grade 201 is no exception. They do not contain toxic substances, do not have  dangerous elements or in danger when combined with other substances. So, please feel free to use the stainless steel in grade 201 and the products made from the stainless steel in grade 201

If there are many advantages like that, the stainless steel in grade 201  has a high price?

Although there are many advantages, the stainless steel in grade 201 has a low price or in other words is quite cheap compared to other stainless steel . The products made from the stainless steel in grade 201 are also cheaper than made of the stainless steel in grade 304 or 316. Therefore, depending on the purpose, The stainless steel in grade 201 is considered a material suitable for everyone because of its relative features good and reasonably priced.

What are the most popular applications of  the stainless steel in grade 201?

The Stainless steel  in grade 201 is quite widely used in life. To fully exploit the features of the stainless steel in grade 201 but still overcome its limitations, The stainless steel in grade 201 is often used to make kitchen appliances such as eating utensils (spoons, forks, bowls, trays, floats). , pan …) Because of its lower corrosion resistance than other stainless steels, The stainless steel in grade 201 is often used for interior decoration instead of exterior decoration. Knowing the properties, advantages and disadvantages helps us choose the most suitable and suitable applications of the stainless steel in grade 201

How to distinguish the stainless steel in grade 201 and the stainless steel in grade 304?

In addition to how to identify through the product surface (the stainless steel in grade 301 is brighter), we test chemical composition . If reagent is used exclusively for stainless steel, reddish brown reaction will appear on the stainless steel in grade 201 while reacting blue or colorless on the stainless steel in grade 304

Where does the stainless steel in grade 201 prestigiously supply?

With stainless steel materials, you need to go to the reputable companies that specialize in supplying stainless steel and have the certificate of origin and the quality certificate to avoid counterfeiting, counterfeiting and poor quality goods.
With products made from stainless steel such as household  stainless steel, you should go to the electronics supermarket, a prestigious household store in the market. Do not buy goods that are floating, unidentified, no brand, without a clear label.
