- Descripción
316Hoja de acero inoxidable L is a low-carbon version of 316 acero inoxidable, widely used in marine engineering, procesamiento químico, pharmaceutical equipment, and high-corrosion environments. pertenece a la 300 series austenitic stainless steel, offering excellent corrosion resistance and improved welding performance compared with standard 316.
Chemical Composition of 316L Stainless Steel
| Elemento | Contenido (%) |
|---|---|
| Cromo (cr) | 16.0 – 18.0 |
| Níquel (En) | 10.0 – 14.0 |
| Molibdeno (Mes) | 2.0 – 3.0 |
| Carbón (do) | ≤ 0.03 |
| Manganeso (Minnesota) | ≤ 2.0 |
| Silicio (Y) | ≤ 1.0 |
| Hierro (fe) | Balance |
The most important difference is the reduced carbon content (≤0,03%), which significantly improves corrosion resistance after welding.
