In this article, Baowu will show you the material of Hastelloy.

Hastelloy is a nickel-based corrosion-resistant alloy, which is mainly divided into two categories: nickel-chromium alloy and nickel-chromium-molybdenum alloy. Hastelloy has good corrosion resistance and thermal stability, and is mostly used in aviation and chemical fields.

Hastelloy mainly has the following grades HASTELLOY B-2, HASTELLOY C-4, HASTELLOY C-22, HASTELLOY G-35, HASTELLOY X.

Hastelloy is mainly divided into three series: B, C, and G. It is mainly used in iron-based Cr-Ni or Cr-Ni-Mo stainless steel, non-metallic materials and other occasions where strong corrosive media cannot be used.

Hastelloy material has excellent corrosion resistance to most corrosive media in the state of oxidation and reduction. And has excellent corrosion resistance, crevice corrosion and stress cracking corrosion properties.

Hastelloy is an ultra-low carbon type, Ni, Mo, Cr series nickel-based, corrosion-resistant, high-temperature resistant material Hastelloy, because it has excellent high temperature resistance, oxidation resistance, and resistance to weld affected areas. Corrosive, with good long-term thermal stability and processability, it is used in harsh industrial environments such as agrochemicals, nuclear facilities, and biopharmaceuticals. It also has excellent corrosion resistance, uniform corrosion resistance and intergranular corrosion resistance in the medium of wet oxygen, sulfurous acid, acetic acid, formic acid and strong oxidizing salt, so it is also widely used in the chemical industry. The electrical conductivity and thermal conductivity of gold are much lower than those of low carbon steel, while the resistivity and expansion rate are much higher than those of low carbon steel.

Hastelloy plates are suitable for various chemical industries containing oxidizing and reducing media. The higher content of molybdenum and chromium makes the alloy resistant to chloride ion corrosion, and the tungsten element further improves the corrosion resistance. At the same time, C-276 Hastelloy tube is one of the only materials resistant to the corrosion of wet chlorine gas, hypochlorite and chlorine dioxide solutions. Significant corrosion resistance.

The above is the relevant content of Hastelloy. If you want to know more, please pay attention to Baowu at any time.
