Alloy 600 Technical Overview
Inconel 600 (UNS N06600) is a nickel-chromium alloy with good oxidation resistance at higher temperatures and resistance to chloride-ion stress-corrosion cracking, corrosion by high-purity water, and caustic corrosion. It is used for furnace components, in chemical and food processing, in nuclear engineering, and for sparking electrodes. The high nickel content of Alloy 600 provides resistance to many organic and inorganic compounds and also makes it virtually immune to chloride-ion stress-corrosion cracking. Steel Emporium offers these pipes and tubes in seamless and welded forms to meet rigorous industrial specifications.
Key Material Advantages
Heat Resistance
Superior oxidation resistance in continuous service up to 2000°F.
Stress Corrosion
Virtually immune to chloride-ion stress corrosion cracking (SCC).
Cryogenic Strength
Maintains excellent mechanical properties at sub-zero temperatures.
