Comparison of Inconel 600 and 601 alloy coils
Gnee Steel is a well-known manufacturer and supplier renowned for producing high-quality INCONEL 600/601 alloy coils, foils, gaskets, and strips. These products are made from INCONEL 600 and 601 alloys and are available in a full range of specifications. INCONEL 600 alloy coils offer excellent heat and corrosion resistance, as well as high strength. These coils are durable, easy to weld, and exhibit superior corrosion resistance in a variety of acidic media. INCONEL 601 alloy coils are reinforced for increased hardness and stress resistance. These coils are available in various shapes and sizes to suit a wide range of applications.
What are the differences between Inconel 600 and 601?
Alloy 600 (UNS N06600) and Alloy 601 (UNS N06601) are the two most widely specified nickel-chromium-iron alloys for coil, strip, foil and shim products. They look similar on paper - both governed by ASTM B168 / ASME SB168 - but they solve different problems: 600 is the corrosion workhorse, 601 is the heat-resistant specialist..
What are the differences between INCONEL 600 coil and INCONEL 601 alloy coil?
INCONEL 600 is a nickel-chromium alloy with superior resistance to high-temperature oxidation. It boasts high strength and stability, capable of withstanding various harsh environments and operating stably at temperatures ranging from low to extremely high. INCONEL 601, on the other hand, incorporates aluminum, enhancing its heat resistance and strength. INCONEL 601 forms a tightly adhering oxide layer, preventing peeling under severe thermal cycling conditions.
INCONEL 600 coil is a thinner, non-magnetic alloy with excellent corrosion resistance and atmospheric oxidation resistance. These foils have a smooth, stain-free surface, higher hardness, and maintain excellent performance even under extreme conditions. INCONEL 601 coil prevents embrittlement caused by prolonged exposure and reduces carburization. It can withstand higher stresses at high temperatures without cracking.
