Hastelloy, nickel-base corrosion-resistant alloy; mainly divided into nickel-molybdenum alloy and nickel-chromium-molybdenum alloy two categories.
Hastelloy wire mesh is ultra-low carbon, Ni, Mo, Cr series nickel base, corrosion resistant, high temperature resistant material Hastelloy, because of its excellent high temperature performance, oxidation resistance, weld effect The corrosion resistance of the zone has good long-term thermal stability and processability. It is used in harsh industrial environments such as agricultural chemicals, nuclear facilities, and biopharmaceuticals. In the medium of moist oxygen, sulfurous acid, acetic acid, formic acid and strong oxidized salt, it also has excellent corrosion resistance, uniform corrosion resistance and resistance to intergranular corrosion, so it is also widely used in the chemical industry, Hastelloy Conductivity and thermal conductivity are much lower than those of low carbon steel, while resistivity and expansion rate are much higher than those of low carbon steel, and the molten pool is poor in fluidity, poor in wettability, low in penetration, and shallow in penetration. Commonly used grades: Hastelloy C-276 B-2 and so on.
