ASTM B446 Inconel 625 Round Bar, 1-12" Diameter, Aerospace UseAlloy UNS N06625 Bars
In the high-stakes aerospace industry, material reliability directly impacts flight safety and performance. Our ASTM B446-compliant Inconel 625 round bars (UNS N06625) are engineered to exceed the most rigorous demands of aircraft and spacecraft manufacturing, offering unmatched strength, corrosion resistance, and thermal stability across a 1-12" diameter range.
Core Material Advantages: The Science Behind UNS N06625
Inconel 625 is a nickel-chromium-molybdenum-niobium alloy renowned for its solid-solution strengthening mechanism—no post-weld heat treatment required to maintain peak performance . Its precise chemical composition (minimum 58% nickel, 20-23% chromium, 8-10% molybdenum, and 3.15-4.15% niobium-tantalum) creates a robust matrix that resists degradation in extreme conditions .
Key physical and mechanical properties include:
- Density: 8.44 g/cm³ (0.305 lbs/in³)
- Tensile Strength: Minimum 760 MPa (110 ksi), reaching up to 960 MPa for annealed variants
- Yield Strength: 345-414 MPa (50-60 ksi) at 0.2% offset
- Elongation: 30% minimum, ensuring ductility for complex fabrication
- Temperature Resilience: Maintains structural integrity from cryogenic environments to 982°C (1800°F), with short-term resistance up to 1095°C (2000°F)
Critical for aerospace, this alloy is non-magnetic (magnetic permeability 1.0006 when annealed) and exhibits low thermal expansion (7.3-7.7 x 10⁻⁶ in/in/°F from 20-427°C), minimizing stress from temperature fluctuations .
ASTM B446 Compliance & Dimensional Precision
Our round bars adhere strictly to ASTM B446, the industry standard for nickel-alloy hot-rolled and cold-drawn bars . This ensures consistent quality across:
- Diameters: 1" to 12", with tight tolerance control (±0.005" for precision grades) to reduce machining waste.
- Surface Finish: Annealed and descaled surfaces (Ra ≤ 1.6 μm) or polished options for critical aerospace components.
- Lengths: Standard 12’-24’ or custom-cut to your specifications, with straightness tolerance ≤ 0.015"/ft.
Each bar is traceable via a unique heat number, with certification including chemical analysis, mechanical test results, and dimensional reports—essential for aerospace quality management systems (e.g., AS9100).
Aerospace Applications: Built for Extreme Flight Conditions
Inconel 625’s versatility makes it indispensable for mission-critical aerospace components :
- Engine Systems: Turbine casings, combustion chamber liners, and exhaust manifolds rely on its 982°C heat resistance and creep resistance to withstand continuous high-temperature operation.
- Structural Components: Landing gear actuators and wing spar fasteners leverage its high tensile strength and fatigue resistance (even after welding).
- Fluid Management: Fuel and hydraulic lines use 1"-4" diameter bars for corrosion resistance against jet fuels and hydraulic fluids.
- Spacecraft Hardware: Rocket thrust chamber tubes and satellite antenna mounts benefit from its low-temperature toughness and resistance to space debris impact.
Aerospace manufacturers also value its weldability—welded joints retain 80% of base metal strength without cracking, eliminating the need for costly post-weld treatments .
Quality Assurance & Value Proposition
Every round bar undergoes rigorous testing:
- Ultrasonic inspection (per AMS 2631) to detect internal defects.
- Eddy current testing for surface flaw detection.
- Batch-specific corrosion testing in simulated aerospace environments (e.g., salt spray, jet fuel exposure).
We supply both annealed (Grade 1) and solution-treated (Grade 2) variants, with Grade 2 optimized for high-temperature creep resistance up to 1000°C . Our 1-12" diameter range eliminates the need for multiple suppliers, while just-in-time delivery supports tight aerospace production schedules.
Why Choose Our UNS N06625 Round Bars?
Aerospace engineers trust our products for:
- Regulatory Readiness: Compliance with ASTM B446, AMS 5666, and AS9100 standards.
- Performance Consistency: Tight control over niobium and molybdenum content ensures uniform strength.
- Cost Efficiency: Precision sizing reduces machining time and material waste.
- Technical Support: Our metallurgists provide application guidance for complex designs (e.g., turbine components).
