1. What is the chemical composition of Inconel 600 / UNS N06600?
Answer:
Inconel 600 (UNS N06600) is primarily composed of:
Nickel (Ni): 72% minimum
Chromium (Cr): 14–17%
Iron (Fe): 6–10%
Manganese (Mn): ≤1%
Silicon (Si): ≤0.5%
Carbon (C): ≤0.15%
This composition gives it excellent corrosion resistance and high-temperature strength.
2. What are the typical applications of this alloy plate?
Answer:
Inconel 600 plates are widely used in:
Chemical processing equipment (reactors, heat exchangers, piping)
Furnace components and gas turbines
Nuclear engineering components
Marine environments and seawater applications
Aerospace parts exposed to high temperature and oxidation
3. What mechanical properties can be expected from hot-rolled Inconel 600 plate?
Answer:
Typical mechanical properties for hot-rolled Inconel 600 plate are:
Tensile strength: 80–120 ksi (550–830 MPa)
Yield strength: 30–50 ksi (205–345 MPa)
Elongation: 30–50%
Hardness: 150–220 HB
These properties make it strong yet ductile for high-temperature applications.
4. What standards does this alloy plate meet?
Answer:
The plate conforms to several standards, such as:
ASTM B444 / B466 – Nickel and nickel alloy plates
UNS N06600 – Standard designation for Inconel 600
AMS 5513 / 5759 – Aerospace material specifications
ASTM G-3 – General corrosion-resistant Inconel alloy standard
Compliance ensures quality and consistency for industrial applications.
5. How should Inconel 600 plate be fabricated or processed?
Answer:
Hot working: Can be hot rolled at 2000–2150°F (1093–1177°C)
Cold working: Can be done but requires intermediate annealing to avoid work hardening
Welding: Easily welded using TIG, MIG, or resistance welding with compatible filler metal
Machining: Difficult due to work hardening; use sharp tools and slow feed rates
Proper processing ensures maximum performance in service conditions.
