Application of 304 stainless steel

304 Steel: Material Knowledge and Application
1. Origin and Development of Materials
304 steel is a high-strength, corrosion-resistant steel grade formed based on industrial development in the mid-20th century. It was originally mainly used for manufacturing building structural components and pipeline equipment, and gradually developed into a widely used high-strength steel with the advancement of technology.
2. Basic components of 304 steel
The main components of 304 steel are as follows:
Carbon (C): Approximately 15% - is one of the main components of steel.
Manganese (Mn): about 9% - improves the strength and corrosion resistance of materials.
Nickel (Ni): about 8% - contributes to good mechanical properties and corrosion resistance.
In addition, 304 steel contains some nitrogen elements to improve its corrosion resistance and heat resistance. The sulfide and oxidized iron-based components also increase its corrosion resistance.
3. Physical properties of 304 steel
304 steel has excellent mechanical properties and corrosion resistance, and its main characteristics are as follows:
High strength: reaches or exceeds 912 MPa (approximately 135 psi) at room temperature.
High strength rust: maintains stable strength even after long-term exposure to humid environments.
Corrosion resistance: Good acid and alkali resistance, still performs well in high temperature, humidity, and chemical corrosion environments.
Fire resistance and melting point: 304 steel has a high fire resistance temperature and melting point, making it suitable for high temperature and high pressure environments.
