What is the concept of stainless steel?
Inox (Stainless Steel), which comes from the French language, can be understood as a type of metal that does not corrode. Stainless steel is essentially an iron alloy with outstanding durability, containing at least 10.5% chromium. An important advantage of stainless steel is its ability to retain color and resist corrosion. Thanks to this characteristic, stainless steel has been widely applied in today’s life, especially as a material in construction projects.
What is stainless steel?
Properties of stainless steel
The characteristics of stainless steel can be considered when compared with low carbon steel. Although there are slight differences depending on the specific type of stainless steel and the field of application in the manufacturing process, nevertheless, in general, stainless steel generally exhibits the following characteristics:
- Excellent corrosion resistance and oxidation resistance.
- Forging hardening rate is higher than carbon steel.
- Good heat resistance and heat preservation.
- High hardness, high durability, good ductility, diverse machining and shaping capabilities.
- Low electrical conductivity.
- Magnetic response is weaker than that of carbon steel. Only certain types of stainless steel, such as those from the Ferritic and Martensitic families, have significant magnetic properties, while stainless steels from the Austenitic family are generally non-magnetic.
In short, thanks to these excellent characteristics, stainless steel has become the preferred choice in many industries. They are widely used in all fields, from manufacturing to processing, architecture and construction.
Properties of stainless steel
How many popular types of stainless steel are there on the market?
Currently, there are hundreds of different types of stainless steel produced. They can be classified into four main families: Austenitic, Ferritic, Duplex and Martensitic. Among them, the most popular stainless steel line is the Austenitic line, with codes such as SUS 301, 304, 316… Next, there are some types of the Ferritic group such as 430, 410 and 201 of Duplex…
Type 304 stainless steel
Stainless steel 304 belongs to the Austenitic group and is one of the most popular stainless steel codes today. Its composition includes 18-20% Chromium and 10% Nickel, besides other major alloys such as iron, manganese, silicon, and carbon…
With high proportions of Nickel and Chromium, 304 stainless steel has excellent corrosion resistance. This makes it a popular material in the production of household appliances, industrial machinery, medical fields, architecture, construction… It is also the most commonly used metal in the household industry. mechanical work.
Type 316 stainless steel
Similar to 304, 316 stainless steel also contains significant amounts of chromium and nickel, along with other components such as silicon, manganese and carbon… The only major difference between 304 and 316 stainless steel lies in the chemical composition. Stainless steel 316 adds a significant amount of molybdenum (accounting for 2 – 3% of the weight). This gives 316 stainless steel much higher corrosion resistance than 304 stainless steel. Therefore, it becomes a preferred choice in the production of medical equipment, food, maritime industry, and mineral exploitation. , nuclear energy and in architecture built in harsh environments.

Type 201 stainless steel
Stainless steel 201 belongs to the Austenitic series and is among about 200 types of stainless steel in this group. Compared to stainless steel 304, stainless steel 201 has higher concentrations of manganese and nitrogen, but a lower percentage of nickel. Because of the difference in alloy composition, Stainless Steel 201 has some unique advantages and disadvantages.
Compared to stainless steel 304, stainless steel 201 has higher hardness and is more susceptible to corrosion. Its surface is also not as shiny as stainless steel 304. However, stainless steel 201 is quite durable, which is its strong point.
Stainless steel 201 is easily machined due to its good formability. Processing methods such as cutting and welding can be performed on this type of stainless steel.
Stainless steel 201 is non-magnetic, so it is often used in products that require resistance to magnetic fields. However, for products requiring magnetism, stainless steel 201 needs to be coated with a layer of stainless steel 410 or 430 on the surface.
Type 430 stainless steel
Stainless steel 430 is the lowest quality stainless steel among stainless steels 201, 304, 316… For processing by welding method, stainless steel 430 is often not highly appreciated for its ability to withstand pressure and its strong impact. The hardness and durability of 430 stainless steel are also low, they are easily broken and deformed. The outstanding strength of Stainless Steel 430 is its high magnetic ability. Therefore, they are often used in products that require non-magnetic properties.
Common applications of Stainless Steel 430 include parts of household electrical appliances, kitchen utensils, interior decoration and devices that require magnetization.

How to identify types of stainless steel on the market
Currently, there are many different types of stainless steel on the market, including: 304 stainless steel, 430 stainless steel, 202 stainless steel, 201 stainless steel, and 316 stainless steel. However, there are three most commonly used types of stainless steel: 304 stainless steel. , stainless steel 430, and stainless steel 201.
– Stainless steel 304: Includes 18% Chromium and 10% Nickel. This is a non-magnetic stainless steel that can be used in all environments, especially safe when in contact with food. However, the price of this product is quite high.
– Stainless steel 201: Includes 18% Chromium and 8% Nickel. This type of stainless steel is also non-magnetic and has outstanding durability over time. However, during use, direct contact with acids or salts should be avoided. The price of this product is not too high.
– Stainless steel 430: Includes 18% Chromium and does not contain Nickel. This type of stainless steel is magnetized and easily affected by the surrounding environment, causing the product to become tarnished and no longer shiny. However, its advantage is that the price is quite cheap.
The rest are uncommon stainless steels such as stainless steel 202, which has similar properties to stainless steel 403. Stainless steel 316 is not magnetized and can be used in any case. Its advantage is that it has high cleanliness and is suitable for industries that require strict cleanliness. However, its weakness is that the price is quite high, so it is only used in special fields.
How to Distinguish Types of Stainless Steel (Stainless Steel)
- Method 1: Based on the stainless steel label and product name on the product body.
- Method 2: Use stainless steel testing solution or magnet. To distinguish 403 Stainless Steel, you can use a magnet, 403 Stainless Steel has very high attraction.
For 304 and 201 stainless steel, you can use acids or specialized testing solutions. When using acid: 304 Stainless Steel has no reaction, while 201 Stainless Steel has a foaming reaction. For the test solution: 201 Stainless Steel will turn brick red, while 304 Stainless Steel will turn gray.
