Chemical Composition of Duplex Round Bars
| Element | Percentage Range | Function/Effect |
| Iron (Fe) | Balance | Primary base element |
| Chromium (Cr) | 21% to 23% | Enhances corrosion resistance, especially in harsh environments |
| Nickel (Ni) | 4.5% to 6.5% | Contributes to high strength and ductility |
| Molybdenum (Mo) | 2.5% to 3.5% | Improves corrosion resistance, especially against chloride-induced pitting and crevice corrosion |
| Nitrogen (N) | 0.08% to 0.20% | Stabilizes the austenitic phase and enhances mechanical properties |
| Manganese (Mn) | Controlled | Improves toughness and reduces susceptibility to cracking |
| Silicon (Si) | Controlled | Enhances oxidation resistance and improves strength |
| Carbon (C) | Controlled | Regulates hardness and strength but kept low to avoid brittleness |
FAQ
What is a Duplex Bar?
Joiners who construct windows are the main consumers of duplex bars. Jewelry making is placed at the highest of any extra spacer bars within the double-glazed piece when it is in the structure. It delivers the look of multiple parts inside the framework.
