FAQ
Q: What is the maximum temperature resistance of ASTM B167 Inconel 601 pipe?
A: Due to its excellent oxidation resistance, Inconel 601 pipe can be used continuously at temperatures up to 1180°C (2150°F).
Q: Can you provide third-party inspection (TPI)?
A: Of course. We regularly collaborate with organizations such as TUV, SGS, BV, and Lloyd's to provide 3.2 certification and witness testing for large infrastructure projects.
Q: Do you provide beveled ends for welding?
A: Yes, we offer a variety of end treatments to suit your installation requirements, including flat (PE), beveled (BE), and threaded ends.
Q: Is Inconel 601 magnetic?
A: Inconel 601 is a nickel-based non-magnetic superalloy composed of nickel-chromium-iron alloy. It possesses excellent properties such as high heat resistance, oxidation resistance, corrosion resistance (including both organic and inorganic compounds), and alkali resistance (making it virtually impervious to chloride stress corrosion cracking).
Q: How machinable is Inconel 601?
A: It exhibits good water corrosion resistance, high mechanical strength, and is easy to form, machine, and weld. These properties make Inconel 601 a widely used material in heat treatment, chemical processing, pollution control, aerospace, and power generation.
