317L Stainless Steel Elbow Products Description
317L Stainless Steel Elbow is an optimized and upgraded stainless steel material based on 316L, with its core advantage stemming from its chemical composition design:
| Key elements | Content range (mass fraction) | core role |
| Chromium (Cr) | 18.00%~20.00% | Forms a dense oxide film, improving basic corrosion resistance. |
| Nickel (Ni) | 11.00%~15.00% | Stabilizes the austenitic structure, enhancing plasticity, toughness, and low-temperature resistance. |
| Molybdenum (Mo) | 3.00%~4.00% | Significantly improves resistance to pitting and crevice corrosion, and is suitable for use with chlorine-containing media. |
| Carbon (C) | ≤0.03% | Ultra-low carbon design avoids intergranular corrosion after welding, ensuring the reliability of welded joints. |
Diameter range: DN15 (1/2 inch) ~ DN600 (24 inch), suitable for pipes with outer diameters from 21.3mm to 630mm; Wall thickness series: SCH5S, SCH10S, SCH20S, SCH40S, SCH80S, etc., to meet different pressure rating requirements (normal working pressure ≤4.0MPa); Bend types: 90° elbow (most common), 180° elbow (U-bend), 45° elbow, some can be customized with special angles such as 30° and 60°; Radius of curvature: Long radius (R=1.5D, D is the pipe outer diameter, standard industrial selection), short radius (R=1D, suitable for space-constrained scenarios).
