Sheath Material Matrix
Darwinheat sheath material selection is based on desired corrosion resistance, temperature tolerance, and water chemistry. Use this guide as a starting point for material choice:
| Material Grade | Performance Level | Key Characteristics | Recommended Application |
| SUS 316L (Stainless Steel) | ★★★★☆ Gold Standard | Excellent corrosion resistance. Contains molybdenum (Mo) to resist pitting from chlorides and alkaline detergents. | Standard & mid-range washing machines |
| Incoloy 840 (Nickel Alloy) | ★★★★★ Premium Grade | Superior stress corrosion resistance. Higher nickel content prevents cracking under thermal shock and hard water scaling. | High-end and industrial washing machines |
