UNS N06625 Inconel 625 Nickel Alloy Strip – High-Temperature Corrosion-Resistant Steel Tape
Overview
UNS N06625, commonly known as Inconel 625, is a high-performance nickel-chromium-molybdenum-niobium alloy renowned for its exceptional resistance to corrosion, oxidation, and mechanical degradation across a wide temperature range—from cryogenic conditions up to 982°C (1800°F). The Inconel 625 nickel alloy strip, often referred to as high-temperature corrosion-resistant steel tape, is widely used in demanding industrial sectors such as aerospace, marine engineering, chemical processing, nuclear energy, and oil & gas.
This product information page provides comprehensive technical details, applications, specifications, and advantages of UNS N06625 nickel alloy strip, optimized for search visibility and user clarity in compliance with Google’s E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) guidelines.
Key Features of Inconel 625 Strip
- Outstanding corrosion resistance in both oxidizing and reducing environments
- Excellent resistance to pitting, crevice corrosion, and stress-corrosion cracking
- High strength and toughness from cryogenic to elevated temperatures
- Superior oxidation resistance up to 1095°C (2000°F) due to protective Cr₂O₃ layer
- Good weldability and fabricability without post-weld heat treatment
- Non-magnetic in annealed condition—ideal for sensitive instrumentation

Applications
Thanks to its unique combination of properties, Inconel 625 strip is critical in the following high-stakes applications:
- Aerospace: Jet engine exhaust systems, thrust reversers, combustion liners
- Marine: Seawater piping, propeller blades, submarine components
- Chemical Processing: Reactors, heat exchangers, acid handling equipment
- Oil & Gas: Downhole instrumentation, sour gas service components
- Nuclear: Control rod drive mechanisms, reactor core internals
- Pollution Control: Flue gas desulfurization (FGD) systems
- Electronics: High-reliability connectors, shielding tapes
Its ability to resist chloride-induced stress corrosion cracking makes it especially valuable in offshore and coastal installations.
Why Choose Inconel 625 Strip Over Alternatives?
Compared to stainless steels (e.g., 316L) or even other nickel alloys like Inconel 600 or Hastelloy C-276, Inconel 625 offers a superior balance of:
- Higher strength without precipitation hardening (due to solid-solution strengthening by Mo and Nb)
- Better fabricability than C-276 while maintaining comparable corrosion resistance
- Longer service life in cyclic thermal environments thanks to stable oxide scale adhesion
- No need for post-weld heat treatment, reducing fabrication costs
This makes it a cost-effective solution over the lifecycle of critical components.
Manufacturing & Quality Assurance
Reputable suppliers produce UNS N06625 nickel alloy strip using vacuum induction melting (VIM) or electric arc remelting (VAR) to ensure ultra-low impurity levels. Each batch undergoes rigorous testing, including:
- Spectrometric chemical analysis
- Tensile and hardness testing
- Ultrasonic or eddy current inspection (for defect detection)
- Intergranular corrosion testing per ASTM G28
- Certification to EN 10204 3.1 or 3.2 standards
Full traceability from melt to final product is maintained for quality-critical industries.
