Stainless steel 304, also known as 18/8 stainless steel due to its composition of approximately 18% chromium and 8% nickel, is the most widely used austenitic stainless steel in industrial applications worldwide. For manufacturers considering how to sell on Alibaba.com, understanding the precise material specifications of 304 grade is essential for meeting international buyer expectations and compliance requirements.
The mechanical properties of 304 stainless steel make it exceptionally versatile for industrial component manufacturing. With a tensile strength ranging from 500-750 MPa, yield strength of 190-230 MPa, and elongation of approximately 45-70%, this grade offers an optimal balance between strength and formability. The hardness typically measures around 215 HB or Rockwell B 70, making it suitable for machining operations while maintaining durability in service [3][4].
304 Stainless Steel Variants: Understanding 304, 304L, and 304H
| Grade | Carbon Content | Key Characteristics | Typical Applications |
|---|---|---|---|
| 304 | ≤0.08% | Standard composition, balanced properties | General industrial components, kitchen equipment, tubing |
| 304L | ≤0.03% | Low carbon, excellent weldability, reduced sensitization | Welded components, large thickness sections, chemical processing |
| 304H | 0.04-0.10% | High carbon, improved high-temperature strength | High-temperature applications, pressure vessels, heat exchangers |
For Southeast Asian exporters targeting the Alibaba.com B2B marketplace, it's crucial to note that 304 stainless steel maintains its austenitic structure even at cryogenic temperatures, making it suitable for diverse climate conditions from tropical Southeast Asia to cold storage applications in export markets. The density of 8.00 g/cc provides a favorable strength-to-weight ratio for shipping and handling considerations [3].
