2. Mechanical Properties:
The tensile strength of Inconel 600 sheet at room temperature (20°C or 68°F) is typically approximately 550 MPa (80 ksi). Yield strength is typically about 240 MPa (35 ksi) at room temperature. Elongation is typically about 30% at room temperature. Nickel alloy 600 has a hardness range between HB 160 and 210.
3. Applicable temperature:
Inconel 600 sheet is a high-temperature alloy with excellent high-temperature properties. Typically, its applicable temperature range is between -253°C to 1093°C (-423°F to 2000°F).
4. Heat Treatment:
AMS 5540 may specify heat treatment conditions or requirements, such as annealing, to achieve desired material properties. For example, alloy 600 uns n06600 heat treatment processes include solution treatment, cooling, aging, and annealing between 1010°C (1850°F) and 1150°C (2100°F).
5. Examples of dimensions and tolerances:
Thickness: 0.025 inches (0.635 mm) to 0.1875 inches (4.76 mm) etc.
Width: 36 inches (914.4mm) or 48 inches (1219.2mm) etc.
Length: 96 inches (2438.4 mm) or 120 inches (3048 mm), etc.
6. Surface finish:
It can specify the surface finish requirements of the din 2.4816 plate, such as polishing or electrolytic polishing, smoothness, or roughness.
7. Applications:
Inconel 600 sheets per AMS 5540 can be used in a variety of applications, including the aerospace industry, chemical processing, and high-temperature heating equipment, where corrosion resistance and high-temperature strength are critical.
8. Resistance to Stress Corrosion Cracking (SCC)
Chloride-Ion SCC Immunity: Standard 300-series stainless steels are notoriously prone to catastrophic stress corrosion cracking in hot chloride-bearing waters or marine air environments under tensile stress. Because AMS 5540 contains more than 72% Nickel, it is virtually immune to chloride-ion stress corrosion cracking.
Resistance to Alkaline Media: It exhibits outstanding resistance to high-temperature, high-concentration caustic alkalis (such as sodium hydroxide), preventing caustic cracking over extended service lifecycles.
9. Weldability, Joint Design, and Post-Weld Processing
Welding Methods: AMS 5540 Inconel 600 sheet can be readily joined using Gas Tungsten Arc Welding (GTAW/TIG), Gas Metal Arc Welding (GMAW/MIG), or Shielded Metal Arc Welding (SMAW).
Filler Metal Selection: To match the high-temperature strength and corrosion resistance of the parent metal, engineers generally specify AWS ERNiCr-3 (commonly known as Inconel Filler Metal 82) or AWS ENiCrFe-3 (Inconel Welding Electrode 182) for welding operations.
Post-Weld Heat Treatment (PWHT): In most standard applications, Inconel 600 components do not require a mandatory post-weld solution annealing because the low carbon content minimizes harmful carbide precipitation at the weld seams. However, for extreme services where maximum dimensional stability or stress relief is mandated, a thermal stress-relief treatment at 870°C to 980°C can be implemented.
