Product type
Austenitic stainless steel is a type of stainless steel characterized by its high chromium and nickel content, which provides excellent corrosion resistance and good formability. This alloy is non-magnetic and maintains its strength at high temperatures, making it suitable for a variety of industrial applications. Commonly used in environments that require durability and resistance to oxidation, austenitic stainless steel is often found in food processing, chemical processing, and construction industries.
| Chemical composition | Typically contains 16-26% chromium and 6-22% nickel |
| Common grades | 304, 316, 321, and 310 |
| Tensile strength | Ranges from 520 to 800 MPa |
| Yield strength | Ranges from 210 to 400 MPa |
| Corrosion resistance | Excellent in a wide range of environments |
| Temperature resistance | Effective at temperatures up to 870°C |
When selecting austenitic stainless steel, buyers should consider the specific grade that best suits their application, as different grades offer varying levels of corrosion resistance and mechanical properties. It's important to specify the required dimensions, tolerances, and any relevant certifications, such as ASTM or ISO standards. Additionally, buyers should determine the quantity needed for their projects to ensure proper supply.
