Inconel 600 and Inconel 601 are very common superalloys. 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.
Basic Information:
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.
introduce:
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-purpose engineering material suitable for applications requiring heat and corrosion resistance. The outstanding property of INCONEL alloy 601 is its resistance to high temperature oxidation.
chemical composition:
As can be seen from the above ingredients, the control standards for sulfur, silicon and manganese in Inconel 600 and Inconel 601 are the same. Sulfur, silicon and manganese are harmful elements in superalloys in most cases. They greatly affect the transient and creep properties of the alloy. The purity of both alloys is very good and the levels of transient and creep properties are the same.
Corrosion resistance:
Inconel 601 has less nickel than Inconel 600, instead it has more chromium with some added aluminum. Nickel plays a very good role in the corrosion resistance of alloys. However, this anti-corrosion effect is relatively limited in resistance to oxidizing environments.
Chromium is a very good antioxidant element. Chromium can form an oxide film on metal surfaces when exposed to oxygen. This oxide film prevents further oxidation of the alloy. This is why almost all super alloys have chromium added.
The large amount of chromium in Inconel 601 ensures that its oxidation resistance (especially high temperature oxidation resistance) is much better than Inconel 600. The added aluminum element can also increase the oxidation resistance of the alloy.
Mechanical behavior:
Inconel 600 and Inconel 601 are both solid solution strengthened alloys. Apart from nickel, chromium and aluminum, the chemical composition of the two alloys is virtually indistinguishable. Therefore, in the same state (solution processing), the mechanical properties of the alloys are almost the same without any 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 Inconel 600 and Inconel 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 is not as good as Inconel 600. This also results in Inconel 601 being used in some specific situations, and its application range is not as wide as Inconel 600.
Supported products:
Both Inconel 600 and Inconel 601 support seamless pipes, welded pipes, capillary pipes, coiled pipes, thick-walled pipes, elbows, flanges, reducers, tees, pipe caps, round rods, flat rods, square rods, hexagonal rods, and plates , coils, strips, wires, poles, filler metals, welding rods and other products in various forms.
Main criteria:
Both Inconel 600 and Inconel 601 comply with a variety of ASTM standards, including seamless pipe and tubing, welded pipe, welded fittings, rods, strips, wires, forgings, plates, sheets, strips, and more.
price:
In theory, Inconel 600 and Inconel 601 cost about the same. But Inconel 600 is more widely used and there are more materials circulating on the market. This makes the Inconel 600 more affordable. So, if the Inconel 600 meets your needs, you might consider it first.
in conclusion:
In terms of antioxidant properties, Inconel 601 is superior to Inconel 600. Otherwise, there are no more differences between the two.
Inconel 600 has a wider range of applications and is therefore more common.
