304 Stainless Steel – Durability and Diverse Applications of Stainless Steel

304 stainless steel is known for its outstanding features such as strong resistance to discoloration, oxidation and corrosion, along with high durability. Because of these features, 304 stainless steel is considered a leading and indispensable material in many different manufacturing industries. In this article, let’s learn and explore types of stainless steel with Saigon Horeca, especially 304 stainless steel.

The concept of 304 stainless steel

Stainless steel, referred to as stainless steel or white steel, is a special type of steel that contains more than 11% chromium. This creates a self-protective film that effectively prevents corrosion. However, the main ingredient is nickel, which provides stability to the Austenitic structure and excellent machinability to stainless steel. Stainless steel code 304, one of the most popular grades globally, is a unique alloy consisting of key components such as nickel, manganese, and chromium, in which the minimum percentage of nickel is 8%.

How to distinguish 304 stainless steel (stainless steel) from regular stainless steel

On the market, there are three popular types of stainless steel: 304 stainless steel (also known as 18/10 with a composition of about 18-20% chromium and 10% nickel); Similar to stainless steel 201 (18/8) and stainless steel 430 (18/0).

304 stainless steel stands out with its high shine, relatively clean surface and excellent rust resistance. Therefore, it often has a higher price than the other two types.

Stainless steel 201 contains a lower percentage of nickel in the composition, while stainless steel 430 contains more iron along with other impurities. This leads to stainless steel 201 and 430 being more susceptible to rust, having lower durability and not being as safe as stainless steel 304. Furthermore, their price is often significantly lower than stainless steel 304.

Let’s explore with Saigon Horeca the unique differences of the above stainless steels:

Stainless steel 201

Type 201 stainless steel demonstrates significant ability to resist corrosion in moderately to mildly corrosive environments. This makes it a reliable material in harsh conditions.

The heat resistance of stainless steel 201 cannot be ignored, with heat resistance from 1149 °C to 1232 °C. It can handle high temperature situations without significant problems.

In addition, 201 stainless steel can be easily machined through welding using basic welding techniques, usually without major difficulties. This feature makes working with 201 stainless steel convenient and flexible.

Despite its outstanding advantages, 201 stainless steel also has some slight weaknesses, such as the ability to be slightly magnetized. However, it remains an attractive option in many different applications.

Stainless steel 304

Stainless steel 304 exhibits excellent corrosion resistance, especially in harsher environments (although this level is lower than stainless steel 316), and is even resistant to environments containing chemicals. This makes it a superior choice in harsh conditions.

The heat resistance of 304 stainless steel is impressive, can withstand temperatures up to 925 °C. Helps it have the ability to work in high temperature environments without difficulty.

304 stainless steel is also known for its ability to work well with all welding methods, making machining and creation more convenient.

In particular, 304 stainless steel is non-magnetic or magnetized at a very low rate, keeping it always maintaining stable performance and quality in many different applications.

Stainless steel 430

Stainless steel 430 has significant corrosion resistance in organic acid and nitric acid environments. In addition, it only exhibits anti-corrosion properties in very mildly corrosive environments, and is carefully controlled to cope with environmental effects.

Stainless steel 430 also has the ability to withstand heat from 815 °C to 870 °C, allowing use in high temperature applications.

However, for welding processing, 430 stainless steel needs to be heated to the appropriate temperature before welding processing can be performed.

The suitable temperature to use stainless steel 430 is between 150°C and 200°C.

The outstanding feature of stainless steel 430 is its high magnetic ability, which should be carefully considered in specific applications.

Practical applications of 304 stainless steel

Stainless steel 304, with its ease of fabrication and outstanding corrosion resistance, has many applications in the food industry. It appears in mixing equipment, milk processing and wine production. Stainless steel 304 is also widely used in pipe systems, yeast making equipment, fermentation vessels, and storage tanks…

In addition, 304 stainless steel is also used in household appliances such as pots, tables, coffee pots, refrigerators, stoves and other cooking equipment. Its ability to withstand corrosion from various chemicals commonly present in fruits, meat and milk is a strong point.

Other application areas of 304 stainless steel include architecture, chemical containers, heat exchange systems, equipment in the mining industry, as well as in the production of nuts, nuts and screws. SUS 304 is also commonly applied in mining and water filtration systems, as well as in the dyeing industry.

How to determine the correct quality 304 stainless steel products?

Although 304 stainless steel has a high price and is becoming the target of many counterfeit products on the market, there is still a way to distinguish products using genuine 304 stainless steel. Here are some methods:

1. Using magnets: Stainless steel 304 is usually not magnetic or has very weak magnetic attraction, while stainless steel 430 has stronger magnetic attraction. By using a magnet, you can test the product’s magnetism to determine the material.
2. Check product information: Always review product information, including product codes and specifications. Stainless steel material 304 is often clearly stated in product information.
3. Visit reputable stores: Buying products from reputable stores with a good reputation in the industry will reduce the risk of purchasing counterfeit goods.
4. Check for magnetization: If possible, check the product after processing using pressure and temperature to shape it. Stainless steel 304 has the ability to transform into Martensite under these conditions, causing magnetization. Quality products usually do not have this phenomenon.
5. Learn about the manufacturer: Learn about the manufacturer and review their reputation. Reputable companies often provide quality 304 stainless steel products.
6. Check certificates: If possible, check that the product has quality, origin and inspection certificates from competent organizations.

Where to buy high quality stainless steel products?

Remember, buying products from trustworthy sources and being careful in checking can help you avoid buying counterfeit goods or products that use substandard materials.
