Allcorr Nickel-Based,UNS N06110，1

### **Product Datasheet: Allcorr® (UNS N06110)** **A Versatile Nickel-Chromium-Molybdenum Alloy with Exceptional Corrosion Resistance** --- #### **1. Overview** **Allcorr®** (UNS N06110) is a modern, versatile **nickel-chromium-molybdenum alloy** designed to offer outstanding corrosion resistance across a wide range of demanding environments. It was developed to provide a more cost-effective and readily available alternative to earlier-generation alloys like C-276, while maintaining excellent performance. Its key characteristic is "all-corrosion" resistance, as the name implies, performing well against pitting, crevice corrosion, stress corrosion cracking (SCC), and general corrosion in both oxidizing and reducing media. It also offers good fabricability and weldability. #### **2. Chemical Composition (Typical Weight %)** The composition is balanced to provide a high level of molybdenum for resistance to reducing conditions and chromium for resistance to oxidizing conditions. | Element | Content (%) | Role in the Alloy | | :--- | :--- | :--- | | **Nickel (Ni)** | Balance (~58-63) | Provides the fundamental corrosion-resistant austenitic matrix. | | **Chromium (Cr)** | ~20.0 - 23.0 | Imparts resistance to oxidizing environments and general corrosion. | | **Molybdenum (Mo)** | ~17.0 - 20.0 | Provides resistance to reducing acids and localized corrosion (pitting/crevice). | | **Iron (Fe)** | ≤ 3.0 | Residual element, kept low to enhance corrosion resistance. | | **Tungsten (W)** | ~1.0 - 2.0 | Enhances resistance to reducing acids and contributes to solid solution strengthening. | | **Cobalt (Co)** | ≤ 2.0 | Residual element. | | **Manganese (Mn)** | ≤ 1.0 | Residual element. | | **Silicon (Si)** | ≤ 0.10 | Residual element, kept very low to prevent detrimental phase formation. | | **Carbon (C)** | ≤ 0.015 | Kept very low to prevent carbide precipitation and sensitization. | | **Vanadium (V)** | ≤ 0.50 | Residual element. | | **Phosphorus (P)** | ≤ 0.030 | Residual element, kept low to improve toughness. | | **Sulfur (S)** | ≤ 0.010 | Residual element, kept very low to improve hot workability and corrosion resistance. | #### **3. Physical Properties (Typical)** | Property | Value / Condition | | :--- | :--- | | **Density** | 8.69 g/cm³ (0.314 lb/in³) | | **Melting Range** | ~1320 - 1370 °C (~2410 - 2500 °F) | | **Thermal Expansion Coefficient** | ~12.3 μm/m·°C (20 - 100°C) | | **Thermal Conductivity** | ~10.8 W/m·K (at 100°C) | | **Modulus of Elasticity** | ~206 GPa (30 x 10⁶ psi) at 20°C | | **Electrical Resistivity** | ~1.30 μΩ·m | #### **4. Mechanical Properties (Typical for Annealed Condition)** **At Room Temperature:** * **Tensile Strength:** ≥ 690 MPa (100 ksi) * **Yield Strength (0.2% Offset):** ≥ 315 MPa (46 ksi) * **Elongation:** ≥ 45% #### **5. Corrosion Resistance** Allcorr is designed for exceptional performance in a broad spectrum of corrosive media: * **Localized Corrosion:** Excellent resistance to **pitting and crevice corrosion** in chloride-containing environments. * **Stress Corrosion Cracking (SCC):** Highly resistant to chloride-induced SCC. * **Acids:** Resists sulfuric acid, phosphoric acid, hydrochloric acid, and organic acids. * **Other Media:** Suitable for use in flue gas desulfurization (FGD) systems, pulp and paper mill environments, and marine applications. #### **6. Product Applications** Allcorr is used across various industries where severe corrosion is a challenge: * **Chemical Processing:** Reactors, vessels, heat exchangers, piping systems, and agitators. * **Pollution Control:** Scrubbers, ducting, and fan components in Flue Gas Desulfurization (FGD) systems. * **Pulp and Paper Industry:** Digesters, bleach washers, and piping. * **Pharmaceutical Industry:** Process equipment requiring high purity and corrosion resistance. * **Marine and Offshore:** Seawater handling systems, pumps, and valves. #### **7. International and Industry Standards** Allcorr (UNS N06110) is covered by several ASTM standards for various product forms. * **UNS:** **N06110** * **ASTM:** * **ASTM B366:** Fittings * **ASTM B574:** Rod & Bar * **ASTM B575:** Plate, Sheet & Strip * **ASTM B622:** Seamless Pipe & Tube * **ASTM B626:** Welded Tube * **ASME:** Approved for use in ASME Boiler and Pressure Vessel Code Section VIII (e.g., SB-575). * **ISO:** ISO 15156-3 (NACE MR0175) for use in sour service environments (oil & gas). --- **Disclaimer:** The information provided herein is for reference purposes only.
