ASTM B167 INCONEL 600 High-Resistance Seamless Tubes for Heat Exchangers
ASTM B167 INCONEL 600 High-Resistance Seamless Tubes for Heat Exchangers
ASTM B167 Inconel 600 high-strength seamless tubing is made of nickel-chromium alloy and is designed for high-temperature and corrosion-resistant applications, such as heat exchangers. It is known for its excellent resistance to high temperatures, redox reactions, chloride-induced stress corrosion cracking, and acidic and alkaline media, maintaining strength across a range from low to high temperatures (2000°C or 1093°C). These tubings are commonly used in critical industries where other materials fail, such as chemical processing, nuclear engineering, and aerospace.
What temperatures can Inconel 600 withstand?
The hot working temperature range for Inconel 600 alloy is 1600 – 2250°F (870 – 1230°C). Heavy-duty working requires temperatures between 1900 – 2250°F (1040 – 1230°C), while light-duty working can be performed at temperatures as low as 1600°F (870°C).
INCONEL (NiCrFe) alloy 600 (UNS N06600/W.Nr. 2.4816) is a standard engineering material suitable for applications requiring corrosion and heat resistance. This alloy also possesses excellent mechanical properties, combining high strength with good machinability.
Advantages of Gnee Steel Inconel 600 Tubing
Using nickel alloy tubing offers three main advantages:
Heat Resistance
Some nickel alloy tubing can withstand extremely high temperatures, thus providing an advantage in mechanical or other high-temperature environments.
Corrosion Resistance of Gnee Steel Inconel 600 Tubing
Oxidation reactions lead to corrosion. Nickel alloys oxidize more slowly than most metals, meaning they have a longer corrosion resistance life.
Low Thermal Expansion Rate of Gnee Steel Inconel 600 Tubing
Many nickel alloy tubings have a very low thermal expansion rate, or their thermal expansion rate can be predicted very precisely. This makes them ideal for high-temperature environments requiring uniform shape.
Gnee Steel Inconel 600 Pipe Manufacturing
Nickel alloy pipes are manufactured using a complex process, starting with the purest raw materials. Contaminated raw materials will result in pipes that do not possess the aforementioned advantages. The manufacturing process includes the following stages:
Smelting
Hot Rolling
Pickling
Annealing
Drawing
Cold Rolling/Slitting
Throughout the manufacturing process, a series of statistical tests are used to ensure quality control.
