Overview
Our UNS N06625 Inconel 625 Round Bar is engineered to meet the rigorous demands of power generation infrastructure, with diameters ranging from 5/8” to 14” and full compliance with ASTM B446/ASME SB 446 standards. As a solid-solution strengthened nickel-chromium-molybdenum-niobium alloy (Werkstoff No. 2.4856), it delivers unmatched performance in high-temperature, corrosive environments—making it the material of choice for critical power generation components.
Key Specifications & Compliance
- Alloy Grade: UNS N06625 (Inconel 625), equivalent to JIS NCF 625 and DIN 2.4856
- Size Range: 5/8” (15.875mm) to 14” (355.6mm) diameter; available in 1–6m lengths (single random, double random, or custom cut)
- Standards Compliance: ASTM B446/ASME SB 446 (primary), plus NACE MR0175/ISO 15156 for sour service compatibility
- Finish Options: Hot Rolled Annealed & Pickled (HRAP), Cold Drawn (CD), Bright Drawn (BD), or Centreless Ground (CG)
- Tolerances: H8–H13 and K9–K12 series for precision fitting
Chemical Composition (ASTM B446 Requirements)
The alloy’s performance stems from its tightly controlled chemistry:
This formulation eliminates the need for precipitation-hardening treatments while delivering exceptional strength and corrosion resistance .
Mechanical & Physical Properties
Ideal for power generation’s extreme conditions, the bar exhibits:
- Tensile Strength: ≥760 MPa (110,231 psi)
- Yield Strength: ≥345 MPa (50,038 psi)
- Elongation: ≥30% (room temperature)
- Hardness: ≤220 HB
- Temperature Stability: -196°C (-320.8°F) to 982°C (1,800°F)
- Density: 8.44 g/cm³ (0.305 lbs/in³)
- Thermal Expansion: 7.3×10⁻⁶ in/in/°F (20–204°C)
Notably, it maintains structural integrity under thermal cycling—critical for gas turbine and nuclear reactor components .
Power Generation Applications
Inconel 625’s unique properties address key challenges in power infrastructure:
- Gas Turbines: Used for turbine blades, combustion chambers, and exhaust manifolds. Its resistance to oxidation and carburization at 982°C prevents premature failure .
- Nuclear Power: Deployed in reactor cores and heat exchangers, where it resists radiation-induced corrosion and maintains strength in high-pressure coolants .
- Coal-Fired Plants: Ideal for boiler tubes and ash-handling systems, as it withstands sulfuric acid corrosion from flue gases .
- Renewable Energy: Utilized in geothermal power pipes and offshore wind turbine drivetrains, enduring saline environments and thermal stress .
Field data shows it extends component lifespan by 30–50% compared to stainless steel in these applications .
Corrosion & Wear Resistance
A standout feature for power generation, the alloy offers:
- Chloride Resistance: Immune to stress-corrosion cracking (SCC) in seawater and brine .
- Acid Resistance: Withstands nitric, phosphoric, and hydrochloric acids (up to 40°C for HCl) .
- Pitting/Crevice Resistance: Outperforms 316L stainless steel in harsh electrolytes .
This resistance reduces maintenance costs and unplanned downtime—critical for power plant reliability.
Fabrication Flexibility
Compliant with ASTM B446, the bar supports standard manufacturing processes:
- Welding: Compatible with TIG, MIG, and resistance welding; no post-weld heat treatment required .
- Machining: Cold working enhances strength without compromising ductility .
- Heat Treatment: Solution annealing (982–1,038°C) optimizes corrosion resistance for specific applications .
Quality Assurance
Each bar undergoes rigorous testing to meet ASTM B446:
- Chemical analysis (XRF/ICP)
- Mechanical testing (tensile, hardness)
- Non-destructive testing (ultrasonic, eddy current)
- Dimensional inspection (calipers, micrometers)
Certifications include mill test reports (MTRs) and ISO 9001:2015 compliance.
Why Choose Our Inconel 625 Bar?
For power generation, reliability is non-negotiable. Our bars deliver:
- ASTM B446 compliance for regulatory approval
- Size versatility (5/8”–14”) for diverse component designs
- Proven performance in nuclear, fossil fuel, and renewable energy
- Global supply chain with just-in-time delivery
