What is Hastelloy alloy?
Hastelloy alloy 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 is a nickel-based alloy widely used in chemical production, and its density is close to that of steel. The specific gravity of steel is 7.9, while the specific gravity of Hastelloy is 8.9. The mechanical properties of Hastelloy are much better than stainless steel. At room temperature, the yield strength of Hastelloy alloy can reach 350MPa, while that of carbon steel is only 235MPa, that is, the toughness of Hastelloy alloy is about 1.5 times that of carbon steel. In terms of hardness, the Vickers hardness of Hastelloy alloy can reach 230, which is higher than 200 of 304 stainless steel. The mechanical properties of Hastelloy with higher nickel content at high temperature are also significantly stronger than stainless steel.
Hastelloy alloy use
Hastelloy alloy 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, Hastelloy tube is one of the only materials that are resistant to corrosion by moist chlorine, hypochlorite and chlorine dioxide solutions, and has significant effects on high-concentration chloride solutions such as ferric chloride and copper chloride. Corrosion resistance.
Because of its characteristics, Hastelloy is widely used in heat exchangers, bellows compensators, chemical equipment, flue gas desulfurization and denitrification, paper industry, aerospace applications, acidic environments, etc.
