What is stainless steel?
Inox, also known as stainless steel, is an iron alloy containing components such as Chromium (Cr) and Nickel (Ni), capable of preventing oxidation and creating a protective layer against corrosion. trail. This material is highly durable, has little corrosion and does not fade.
Popular types of stainless steel on the market today
Currently, on the market there are many types of stainless steel with different names and characteristics. However, among them there are 4 most popular types of stainless steel: stainless steel 304, stainless steel 201, stainless steel 316 and stainless steel 410.
- Stainless steel 304 is highly appreciated by manufacturers because it has the best durability and resistance to oxidation among all types of stainless steel. With 18% chromium, 10% nickel and a small amount of iron, 304 stainless steel never rusts when used.
- Stainless steel 201 contains 18% chromium, 3% nickel, iron and other components. Stainless steel 201 has relatively good durability and is often used to produce common items in daily life such as pots, pans, electric kettles, thermos flasks,…
- Stainless steel 316 is a type of stainless steel with very high corrosion resistance, superior to stainless steel 304. Often widely used in industrial construction, production of materials resistant to marine environments, tanks, and chemical pipes for ship,…
- Stainless steel 410 is also a popular type of stainless steel in everyday life. With high strength and hardness, stainless steel 410 also has good abrasion resistance and machining resistance. Often used in mechanical parts, items such as specialized pots for induction cookers, knives, chopsticks, spoons, stainless steel baskets,…
Separate common types of stainless steel
Method 1: Distinguishing method by spark grinding: This is a quick and effective method to distinguish stainless steel, often applied during the production process. However, it requires meticulous observation and experience of the worker.
- Stainless steel with code 4xx: Due to its high chromium content and low nickel content, when grinding, it will create dark orange sparks and at the end of the spark will bloom into a flower shape.
- Stainless steel with code 3xx: In this stainless steel group, when grinding, it will create orange-yellow sparks, a small number of fire petals, and along the sparks there are flashing light spots.
- Stainless steel with code 2xx: Due to the nickel component being replaced by manganese, if compared to the same thickness with 3xx stainless steel, it will feel harder when bent. When grinding on stone, the spark will be bright orange, the spark will be thick in the shape of a fire flower with more petals than the 3xx type…
Method 2: Use special reagents: Using special chemicals to test will help distinguish some types of stainless steel based on color.
Method 3: Distinguishing stainless steel by special machinery analysis method: This method provides accurate results, but has the disadvantage of requiring high cost, long waiting time for analysis results and is not suitable for analysis. use in daily life.
Method 4: Distinguish stainless steel based on non-magnetic or magnetic properties (attracted by magnets) to determine the type of stainless steel.
Stainless steels with codes starting with 2xx or 3xx are austenitic and theoretically are completely non-magnetic. However, this group will become significantly stiffer when deformed after cooling. Therefore, in practice, distinguishing stainless steel with codes starting with 2xx or 3xx using magnets is difficult and can cause confusion.
Which type of stainless steel is the best on the market today?
To evaluate which type of stainless steel is best, it depends on the specific usage requirements. For example, if considering corrosion resistance, 316 stainless steel is the best type, followed by 304 stainless steel, 201 stainless steel and finally 430 stainless steel.
As for humid, near the sea or highly acidic environments, 316 stainless steel is the best type thanks to its high durability and good corrosion resistance. Meanwhile, 304 stainless steel is the best type for normal environments, with no special requirements for corrosion resistance.
For normal environments, not too harsh and low cost requirements, stainless steel 201 and stainless steel 430 are the best types of stainless steel.
