Inconel® Alloy 600 (UNS N06600)
Inconel® Alloy 600 is a premier nickel-chromium material engineered for use in environments ranging from cryogenic temperatures to soaring heat levels exceeding 2000°F (1093 °C). This "standard-bearer" of the Inconel family features a high nickel content, which provides immunity to chloride-ion stress corrosion cracking, while the chromium addition ensures robust resistance to sulfur compounds and oxidizing conditions.
At Aries Alloys, we supply Inconel 600 to industries where the combination of thermal stability and chemical resistance is non-negotiable. Our stock is meticulously managed to ensure that every component maintains the mechanical strength and structural integrity required for high-stress industrial furnace and chemical processing applications.
Essential Performance Traits
- Thermal Oxidation Resistance: Capable of withstanding repeated heating and cooling cycles without significant scaling or metal loss.
- Immunity to Stress Cracking: The high nickel base makes it virtually immune to chloride-induced stress corrosion cracking, a common failure point for stainless steels.
- Versatile Chemical Defense: Resists a wide spectrum of corrosives, including dry chlorine, hydrochloric acid, and caustic soda.
- High-Temperature Strength: Retains impressive mechanical properties and creep resistance at temperatures where many metals would soften or fail.
- Non-Magnetic Nature: Its austenitic structure remains non-magnetic even after cold working, making it ideal for specialized electronic and instrument housings.
Material Science & Data
Alloying Architecture:
The chemistry of Alloy 600 is dominated by Nickel (minimum 72%) and Chromium (14-17%). This specific ratio creates a protective oxide layer that is both tenacious and self-healing, providing a formidable barrier against aggressive atmospheres.
Technical Indicators:
- Excellent weldability using standard commercial techniques.
- High resistance to carburization and nitriding environments.
- Superior impact strength at sub-zero and cryogenic temperatures.
- Balanced ductility for ease of fabrication and cold forming.
