How Many Types of Stainless Steel 304 Are There?
Stainless Steel 304 consists of three main types: 304L, 304N, and 304H. Stainless Steel 304L has a very low carbon content, less than 0.03%, and a high nickel content to prevent the formation of chromium carbides during processing.Stainless Steel 304H has a higher carbon content, exceeding 0.08%, and is used for products requiring high-temperature resistance.
Stainless Steel 304N has a limited carbon content of a maximum of 0.08% and is not suitable for applications requiring welding, corrosive environments, or high temperatures. Stainless Steel 304 is often used to produce products that do not require welding or require minimal processing.
Outstanding Advantages of Stainless Steel 304:
Superior Corrosion Resistance and Durability of Stainless Steel 304:
Stainless Steel 304 stands out with its extremely powerful corrosion resistance and exceptional durability over time.Its general corrosion resistance is not affected when in contact with various chemicals. Even in the presence of highly corrosive chemicals, Stainless Steel 304 maintains stable properties and remains unaffected.
The corrosion resistance and durability of Stainless Steel 304 make it a top choice in many industries, especially in food processing and household appliance manufacturing.
Recyclability of Stainless Steel:
Stainless steel is a recyclable material without losing its important properties. The raw materials used to produce stainless steel can be recycled indefinitely to create new products.
Easy Cleaning and Maintenance:
With its corrosion resistance and bright surface, stainless steel equipment is easy to clean and maintain. This not only keeps the product aesthetically pleasing but also enhances usability and convenience in daily use.
Ensuring Consumer Health:
Stainless Steel does not contain harmful chemicals, making it a top choice in the production of medical instruments, sterilization equipment, and the food processing industry.
Ease of Fabrication and Shaping:
Stainless Steel 304 exhibits higher hardness than conventional steels, but it is not excessively hard. With its austenitic characteristics, Stainless Steel 304 is easy to process through cutting, bending, and machining. This makes the production and processing of Stainless Steel 304 products convenient.
High Hardness:
The high tensile strength, heat resistance, hardness, and ductility of Stainless Steel 304 make it easy to process and shape. This opens up many possibilities for manufacturing complex and diverse-shaped products.
Weldability of Stainless Steel 304:
Stainless Steel 304 has excellent weldability without the need for preheating. However, when welding large cut surfaces or welds that may be subject to decay, post-weld heat treatment or the use of ultra-low carbon stainless steel such as 304L or stabilized 321, 347 stainless steel to limit weld decay is necessary.Commonly used filler metals for welding Stainless Steel 304 are E308 and E309. E308L can be used when the temperature reaches 370°C (700°F).
Characteristics of Stainless Steel 304:
- Affordable Price: The price of Stainless Steel 304 ranges from 50,000 to 70,000 VND/kg, making it a popular choice with reasonable pricing and meeting requirements for strength, repeatability, and ease of machining.
- High Hardness: SUS 304 belongs to the Austenitic group, making it harder than regular steel. However, for special cases, hardening through martensitic or precipitation hardening is required.
- Easy Rolling, Bending, Ductile: Stainless Steel 304 is easily formable, does not require heat treatment, and can be easily formed into thin products. It is also very easy to weld and suitable for many welding processes.
- Excellent Corrosion Resistance: With chromium in its structure, Stainless Steel 304 has excellent resistance to oxidation, rusting, and corrosion in water, air, acids, and many types of chemicals.
- High Heat Resistance: Stainless Steel 304 contains nickel, helping to avoid low-temperature brittleness and withstand high temperatures ranging from 425 to 860 °C.
Stainless Steel 304 finds diverse applications in daily life and various industries, including the food industry, automotive, chemicals, water treatment, aerospace, and space exploration. It is used to manufacture household appliances, medical equipment, architectural decorative materials, and everyday items such as dining sets, stainless steel pans, bowls, steamers, BBQ grills, and many other products.
These advantages, together, contribute to the popularity and reliability of products made from Stainless Steel in various fields.
