Stainless steel 201 or also known as stainless steel sus 201, these are names that are no longer strange to us when mentioning stainless steel. Normally, we often think that there is only one type of stainless steel. However, few people know that stainless steel can be divided into many different types and has many practical applications. Among them, stainless steel 201 is also highly appreciated for its durability and quality. So what is stainless steel 201? Let’s follow the article below to learn about the outstanding advantages of stainless steel 201.

What is stainless steel 201?
Stainless steel 201 is one of 200 types of stainless steel, belonging to the Austenitic family (including Austenitic, Ferritic, Austenitic-Ferritic (Duplex), Martensitic, Precipitation Hardening). Stainless steel 201 has higher Manganese and Nitrogen content, and lower Nickel content. This difference in composition makes 201 stainless steel have different properties compared to other types of stainless steel.
Structural composition of stainless steel 201?
The above information has helped us find out the answer to the question What is stainless steel 201? So what chemical components is 201 stainless steel made of?
Unlike other types of stainless steel such as 304 stainless steel, 301 stainless steel… whose main component is nickel, 201 stainless steel stands out with its main component being manganese and this is also the characteristic feature of this type of 201 stainless steel.
Specifically, the chemical composition that makes up Stainless Steel 201 has the following proportions:
- Fe: accounts for about 72%.
- Cr: accounts for about 16 to 18%.
- Mn: accounts for about 5.5 to 7.5%.
- Ni: accounts for about 3.5 to 5.5%.
- N: accounts for about 0.25%
- Si: accounts for about 1%.
- C: accounts for about 0.15%.
Classification of stainless steel 201?
Based on the structural composition, Stainless Steel 201 has two main types: Stainless Steel 201 and Stainless Steel 201LN. During solution annealing, Stainless Steel 201/201LN undergoes Martensitic transformation due to temperature differences. Below is detailed information about these two types of 201 stainless steel:
- Stainless steel 201:
Stainless steel 201 is an alloy with high hardness. Compared to other types of stainless steel, it has a large chromium content, good formability, corrosion resistance and high durability. Stainless steel 201 has good machinability equivalent to stainless steel 304, but has lower corrosion resistance.
- Inox 201LN:
Stainless steel 201LN has the ability to bend and shape easily. Grade 201LN stainless steel has similar properties to other types of stainless steel, with good oxidation resistance and excellent toughness, even at low temperatures.
Characteristics of stainless steel 201?
Like other types of stainless steel, 201 stainless steel also has the characteristics of sustainability, corrosion resistance, heat resistance, easy cleaning and aesthetics. However, due to different chemical compositions, the advantages of this type of stainless steel also have small differences compared to other types of stainless steel. Below are some characteristics of 201 stainless steel that are popular with many people.
- Stainless steel 201 has good formability and is easy to process by methods such as welding or cutting, so it is widely used in the household appliance industry.
- Stainless steel 201 has little magnetic properties, only slightly attracted to magnets. However, after being processed, its magnetic properties become stronger.
- Stainless steel 201 has characteristic durability, stable quality, good heat resistance and corrosion resistance in wet conditions. However, because the chromium content in 201 stainless steel is 2% less than 304 stainless steel, 201 stainless steel has lower corrosion resistance than 304 stainless steel.
- The lifespan of 201 stainless steel is quite high, ranging from 15 to 20 years of use.
Applications of stainless steel 201?
Manganese is the main ingredient in 201 stainless steel, so 201 stainless steel has the advantage of being able to withstand hardness, good strength and corrosion resistance. With a reasonable price, this material is commonly used in many fields and daily life, including:
- Interior decoration: Stainless steel 201 is used in stairs, TV shelves, railings, windows…
- Tables and chairs: Stainless steel 201 is used to create modern, luxurious stainless steel tables and chairs, suitable for many different purposes. You can see all kinds of stainless steel dining tables, stainless steel round tables, industrial dining tables, 3-tier tables, bench tables, 304 stainless steel chairs, folding table chairs, restaurant chairs, round-legged chairs, stainless steel stools, chairs. Stirrups… all prioritize using 201 stainless steel.
- Kitchen equipment: Stainless steel 201 is used in sinks, utensils, shelves, rice steamers, dining trays… bringing luxury and creating a cozy and sophisticated space for the family.
- Medical equipment: Stainless steel 201 is used in cabinets, beds, swivel chairs, injection carts… to ensure hygiene and safety for patients.
- School equipment: Stainless steel 201 is used in single student desks, table and chair sets, backrest chairs… convenient and saves classroom space.
Frequently asked questions about stainless steel 201
Can 201 stainless steel conduct electricity?
Does stainless steel 201 conduct electricity? This is a question that attracts a lot of attention from customers and experts. Results from tests show that 201 stainless steel has the ability to conduct electricity, but its conductivity level is very low, almost negligible. Therefore, stainless steel 201 has never been used in the production of products that require electrical conductivity. So customers can rest assured when using 201 stainless steel without worrying about the electrical conductivity of this material.
What temperature can 201 stainless steel withstand?
Melting temperature of stainless steel 201: 1400-1450 ° C. However, stainless steel 201 has good heat resistance, this type of stainless steel is not only able to withstand high temperatures but also has the ability to withstand heat in cold weather conditions. long period of time.
Does 201 stainless steel rust?
In the list of stainless steel types, only 304 stainless steel does not rust. However, stainless steel 201 has lower corrosion resistance than stainless steel 304, so after a period of use, rust and discoloration may appear on the surface. The specific time for the rusting process of 201 stainless steel is not clearly defined, but depends on how it is used and preserved by the user. If 201 stainless steel is regularly exposed to chemicals, strong detergents and humid environments, rust will occur more quickly.
