What Is Inconel 600 Strip?

Inconel 600 strip is a nickel-chromium alloy strip designed for use from cryogenic to elevated temperatures in the range of 2000 deg F(1093 deg C).

It is non magnetic, has excellent mechanical properties, and presents the desirable combination of high strength and good weldability under a wide range of temperatures.

What Are The Characteristics Of Inconel 600 Strip?

Alloy 600 strip is also known as UNS N06600 alloy strip.

The main characteristics about Inconel 600 strip are:

Heat resistance: Inconel 600 strip has excellent resistance to oxidation at high temperatures. It can withstand up to 2200°F (1204°C) before being affected by corrosion. This property makes it suitable for use in extreme environments such as those found in aircraft engines and hot water pipes.

Corrosion resistance: Inconel 600 strip has excellent corrosion resistance when exposed to seawater, steam or other substances that contain chlorides or sulfates. This property makes it ideal for use in marine environments where it may come into contact with saltwater during its lifetime. It is also suitable for applications where there will be exposure to chloride-containing coolants such as sodium chloride or potassium chloride.

Strength: The strength of Inconel 600 strip is similar to that of steel but it weighs less than 20 times less than steel per unit area so it can be used in applications where weight matters such as aircraft engines or satellites.

How To Produce One Roll Inconel 600 Strip?

Casting: Inconel 600 alloy melts can absorb a large amount of gas and undergo strong oxidation. Generally, induction furnace is used for smelting, the surface of the melt is covered with glass, and charcoal, manganese, silicon, magnesium, titanium, etc. are used for deoxidation. The melting temperature is between 1450 and 1560 °C, which varies with the alloy. Usually flat ingots are cast in pig iron molds (see cast iron mold ingots) or semi-continuous casting (see semi-continuous ingot casting). Ingot weight in the range of 30kg to 400kg. Defects such as inclusions and cold partitions on the surface of the ingot should be cleaned up.

Hot rolling: Inconel 600 alloys have good high-temperature plasticity and high deformation resistance. If a gas stove is used, the sulfur content of the gas must be strictly controlled to avoid hot brittleness. A nickel ingot weighing 400kg and having a thickness of 200mm was hot rolled to a thickness of 10mm through 11 passes. Sometimes it is forged before hot rolling to improve the internal structure.

Pickling: Inconel 600 alloys are easy to stick to the tool when milling surfaces (see milling of non-ferrous alloy ingots), so pickling is commonly used for hot-rolled slabs to remove surface oxides. Pickling uses a mixed acid of sulfuric acid and nitric acid, or nitric acid alone. In order to improve the effect of pickling, cold rolling is performed with a small reduction before pickling, so that the oxide layer whose extension is smaller than the matrix is ​​broken, so as to facilitate the reaction with acid.

Cold rolling: Hot rolled Inconel 600 alloy billets with a thickness of 5.0 to 13.5 mm need to undergo repeated cold rolling and annealing to reach the finished product thickness. The reduction ratio between two anneals can reach 70% to 85%. Four-high rolling mills are commonly used in cold rolling. High-strength nickel alloy strips are finish rolled in 12-high or 20-high mills. During cold rolling, it should be fully lubricated and cooled to prevent sticking to the roll and affecting the surface quality.

Annealing: Annealing is divided into intermediate annealing and finish annealing. The purpose of intermediate annealing is to eliminate work hardening caused by cold rolling; finish annealing is to control finished product properties. The temperature for complete annealing of Inconel 600 alloy is between 570 and 850 IC, depending on alloy composition and product thickness. The coiled strip is easy to bond when annealed, so it should be re-rolled before annealing. Because the oxide scale of nickel alloys is difficult to remove, bell-type vacuum furnaces are often used for annealing. Nickel-aluminum, nickel-titanium and other complex nickel alloys can be precipitation hardened by solution/aging treatment to increase strength.

Tempering: The purpose of tempering is to restore hardness in order to improve impact strength, tensile strength (tensile strength) and fatigue resistance (fatigue strength) of alloy strips after annealing treatment.

Strip straightening: Straightening ensures that the product has high dimensional accuracy and flatness with no deformation such as bends or kinks in it. This step can be done either manually or mechanically using a straightener machine or press brake arrangement with automatic measurement system to ensure dimensional accuracy of the strip being processed.

Slitting Process: For different thickness of Inconel 600 strip slitting process, the small and large slitting machines will be used by our team. Our larger slitting machines can cut hot rolled mother coils from mill origin directly. Thickness is from 2mm to 6mm.

And meantime we use the small machines to cut the narrow strip coils as precision strips. Thickness is from 0.02mm to 3.0mm.

Our workers will make adjustments between coils and cutting tools when they are preparing to slit in order to minimize the burr of strips edge as much as possible.

Packaging Process: To a certain extent, exquisite standard sea packaging reflects one supplier‘s service. It greatly influences the client’s next purchasing plans.

One kind of packaging is called wooden pallet. And the fumigation wooden pallets and non-fumigation pallets are two kinds of pallets type.

Eye to eye or eye to wall types of packaging alloy strips will be adopted before shipment.

The surface finish of metal strips will be packaged with waterproof paper. Then coating the PVC film on this paper.

After that, the banding strap will be used for fastening pallets and strips products.

Before placing the metal strips into the wooden case, the strips are packaged with perfect packaging.

Wooden case and four corners shall not be smaller than the outer diameter of the total strips.

In addition, clear labels are tagged on the outside of these sea standard packages for easy identification of these nickel alloy strips specifications and quality information.
