1. What are the chemical compositions of Inconel 625 (UNS N06625) and UNS N06600?
Answer:
Inconel 625 (UNS N06625):
Nickel: ≥58%
Chromium: 20–23%
Molybdenum: 8–10%
Niobium + Tantalum: 3.15–4.15%
Iron: ≤5%
Trace amounts of C, Mn, Si
UNS N06600: Primarily nickel (~99%), with small additions of carbon, iron, and manganese.
These compositions provide excellent corrosion resistance and high-temperature strength.
2. What mechanical properties can be expected from these materials?
Answer:
Inconel 625 Plate/Sheet:
Tensile strength: 120–180 ksi (830–1240 MPa)
Yield strength: 60–100 ksi (415–690 MPa)
Elongation: ≥30%
UNS N06600 Coil:
Tensile strength: 34–55 ksi (235–380 MPa)
Yield strength: 14–28 ksi (95–195 MPa)
Elongation: ≥30%
These properties make them suitable for extreme environments, including high temperatures and corrosive conditions.
3. What forms and sizes are available?
Answer:
Forms: Plates, sheets, coils, strips
Thickness: 0.5 mm to 200 mm (depending on form)
Width: 100 mm to 2000 mm
Surface finish: Mill finish, bright finish, or polished as per customer requirement
4. What are the typical applications?
Answer:
Inconel 625: Aerospace components, marine equipment, chemical processing, heat exchangers, gas turbines, and high-temperature exhaust systems
UNS N06600 Nickel: Electrodes, chemical vessels, marine equipment, and battery components
Both alloys are highly corrosion-resistant and perform well in oxidizing and reducing environments.
5. What standards and certifications do these products comply with?
Answer:
Standards: ASTM B444 (Inconel 625 Plate/Sheet), ASTM B168 (UNS N06600 Coil)
Certifications: Mill Test Certificates (MTC), ISO 9001, ASME, PED (for pressure vessel applications)
These ensure consistent chemical composition, mechanical properties, and quality control.
