Is nickel-based alloy steel Hastelloy?
Hastelloy is one of the broad categories of nickel-based alloys.
Hastelloy is a nickel-based alloy, and nickel-based alloys are not necessarily Hastelloy!
Nickel-based alloy refers to a type of alloy that has comprehensive properties such as high strength and certain resistance to oxidation and corrosion at high temperatures of 650 to 1000°C. According to the main properties, they are further divided into nickel-based heat-resistant alloys, nickel-based corrosion-resistant alloys, nickel-based wear-resistant alloys, nickel-based precision alloys and nickel-based shape memory alloys. High-temperature alloys are divided into iron-based high-temperature alloys, nickel-based high-temperature alloys and cobalt-based high-temperature alloys according to different substrates. Among them, nickel-based high-temperature alloys are referred to as nickel-based alloys.

Corrosion resistance and main use environment: Hastelloy C-276 is a tungsten-containing nickel-chromium-molybdenum alloy with extremely low silicon-carbon content and is considered a universal anti-corrosion alloy. This alloy has the following characteristics: ① It has excellent corrosion resistance to most corrosive media in both oxidizing and reducing atmosphere states. ②Excellent resistance to pitting corrosion, crevice corrosion and stress corrosion. The higher molybdenum and chromium content makes the alloy resistant to chloride ion corrosion, and the tungsten element further improves the corrosion resistance. At the same time, C-276 alloy is one of the only materials resistant to corrosion by moist chlorine, hypochlorite and chlorine dioxide solutions, and has significant resistance to high-concentration chloride solutions such as ferric chloride and copper chloride. Corrosion resistance. It is suitable for sulfuric acid solutions of various concentrations and is one of the few materials that can be used in hot concentrated sulfuric acid solutions.
