Difference Between Inconel 600 vs 601
Inconel 600 and Inconel 601 are very common high temperature alloys. Both alloys have good high temperature properties. Among them, Inconel 601 adds more chromium elements based on Inconel 600. Therefore, their main difference lies in their antioxidant properties.
Introduce Inconel 600 and 601
Inconel 600 (UNS N06600/ W.Nr. 2.4816) is a standard engineering material suitable for applications requiring corrosion and heat resistance. The alloy also has excellent mechanical properties, presenting an ideal combination of high strength and good processability.
Inconel 601 (UNS N06601/ W.Nr. 2.4851) is a general engineering material suitable for applications requiring heat and corrosion resistance. The outstanding property of INCONEL 601 alloy is its resistance to high temperature oxidation.
Density
Inconel 600 and Inconel 601 are both INCONEL® brand products. They are mainly composed of nickel, chromium and iron and are solid solution strengthened alloys. Their densities are 8.47 g/cm3 and 8.11 g/cm3 respectively, both of which are suitable for high temperature environments.
Chemical Composition:
It can be seen from the above ingredients that the control standards for sulfur, silicon and manganese in Inconel 600 UNS N06600 and Inconel 601 UNS N06601 are the same. In most cases, sulfur, silicon and manganese are harmful elements in superalloys. They greatly affect the transient and creep properties of the alloy. The purity of both alloys is very good and the transient and creep performance levels are the same.
Corrosion Resistance
In terms of corrosion resistance, both materials offer excellent protection against many different corrosive agents, such as acids, alkalis, and salt water solutions. However, when subjected to oxidizing environments (such as nitric acid or hydrochloric acid mixed with oxygen or air bubbles respectively), Inconel 601 tube provides superior corrosion protection compared to 600 because it has added aluminum in its composition, which helps in A protective oxide layer forms on its surface. The surface of the alloy is faster than its counterpart.
Mechanical Behavior:
2.4816 Inconel 600 and Inconel 601 are both solid solution strengthened alloys. Apart from nickel, chromium and aluminum, there is little difference in the chemical composition of the two alloys. Therefore, in the same state (solid solution processing), the mechanical properties of the alloys are almost the same without significant differences.
Physical Properties:
The physical properties such as density, melting range, magnetic permeability and Curie temperature of Inconel 600 and Inconel 601 are also different, but the difference is not significant.
Application:
Both ALLOY 600 and 601 are widely used in automotive, chemical processing, resistance, welding products and other fields. However, since Inconel 601 is mainly used to improve the oxidation resistance of the alloy, its other corrosion resistance properties are not as good as Inconel 600. This also results in nickel alloy 601 being only used in some specific applications, and its application range is not as wide as Inconel 600.
Main Criteria:
Both Inconel 600 and Inconel 601 comply with various ASTM B444, B474, B366, B564, B168 standards, including seamless pipe, welded pipe, welded fittings, rod, wire, forgings, plate, sheet, strip and more.
Price:
In theory, Inconel 600 and Inconel 601 cost about the same. However, Inconel 600 is more widely used and there are more materials circulating in the market. This makes the Inconel 600 more affordable. So, if the Inconel 600 meets your needs, you can consider it first.
