| Difference | SUS 304 | SUS 304 L |
|
Characteristics |
- Austenitic basic steel, the most widely used; - Excellent corrosion resistance and heat resistance; - Excellent low temperature strength and mechanical properties;- Single-phase austenitic structure, no heat treatment hardening phenomenon |
Compared with 304 excellent corrosion resistance. |
| Uses |
-1, 2 kinds of tableware, exterior materials, building materials, auto parts, - Medical devices, chemistry, food technology, fiber industry, - Ship parts |
- Chemical, coal, oil industry equipment with high resistance to grain boundary corrosion, - Building materials, heat-resistant parts and components that are difficult to heat-treat |
