Comparison information between Nickel 600 and AISI 308L stainless steel

Comparison information between Nickel 600 and AISI 308L stainless steel
The main difference is that Nickel 600 is a nickel-based superalloy designed for extreme high-temperature and highly corrosive environments, while AISI 308L is an iron-based stainless steel suitable for general corrosion resistance in medium-temperature applications.
Is Inconel 600 magnetic?
Inconel 600 is non-magnetic, possesses excellent mechanical properties, combining high strength with good machinability and ease of welding. The 600 alloy exhibits cold-forming characteristics generally similar to chromium-nickel stainless steel.

Nickel 600 is a nickel alloy specifically formulated for initial forming of forged products. NA14 is the British Standard (BS) designation for this material, and N06600 is its United Nations Standard (UNS) designation. Nickel alloy 600 is its commonly used industry name. Additionally, its French Association for Standardization (AFNOR) designation is NC15Fe.
AISI 308L stainless steel is an austenitic stainless steel designed for initial forming of forged products. The listed performance parameters apply to the annealed state. 308L is the AISI grade for this material. S30880 is its UNS designation. It has relatively low tensile strength and ductility among forged austenitic stainless steels.
Comparison of the composition and classification of nickel 600 and AISI 308L stainless steel
| Property | Nickel 600 (Inconel 600, UNS NO6600) | AISI 308L Stainless Steel (UNS S30880) |
|---|---|---|
| Base Metal | Nickel (~72% minimum) | Iron (~65%+) |
| Main Alloying Elements | Chromium (14-17%), Iron (6-10%) | Chromium (~20%), Nickel (~11%) |
| Material Class | Nickel Alloy (Superalloy) | Austenitic Stainless Steel |
Comparison of the properties and characteristics of nickel 600 and AISI 308L stainless steel
| Property | Nickel 600 | AISI 308L Stainless Steel |
|---|---|---|
| High Temperature | Excellent strength, creep resistance, and oxidation resistance up to ~1093°C (2000°F) | Strength drops significantly above ~870°C (1600°F); susceptible to creep |
| Corrosion Resistance | Superior resistance to a wide range of aggressive chemicals, including chloride-ion stress-corrosion cracking | Good general corrosion resistance, but more vulnerable to localized attack (pitting, crevice corrosion, stress corrosion cracking) in harsh, hot chloride environments |
| Mechanical Strength | Stronger and more durable in extreme conditions | Lower strength compared to Ni 600, especially at high temperatures |
| Fabrication | Difficult to machine and weld due to rapid work-hardening | Easier to machine and fabricate |
Cost and Applications
Cost: Due to its high nickel content and special properties, Nickel 600 is significantly more expensive (potentially 5-10 times more expensive than other materials).
Applications of Nickel 600 and AISI 308L Stainless Steel:
Nickel 600 is used in applications with extremely high performance requirements, such as aerospace, gas turbines, nuclear engineering, and chemical equipment, where extreme conditions are often present.
AISI 308L is widely used in general industrial, construction, and food processing applications. It is most commonly used as a filler material when welding 304 stainless steel.
