哈氏合金是一种镍基耐腐蚀合金。
哈氏合金是一种费用昂贵、且耐酸性侵蚀特别强的一种合金质料，它的力学机能胜过不锈钢质料几十倍，能在侵蚀情况连续运用几十年的光阴。主岩亩隐要分成镍铬合金与镍铬钼合金两大类。哈氏合金具有良好的抗腐蚀性和热粗厅稳定性，多用于航空事业，化学领域等。
Hastelloy is a nickel based corrosion-resistant alloy.
Hastelloy is an expensive and highly resistant alloy material to acid erosion. Its mechanical properties are dozens of times better than stainless steel materials, and it can be continuously used for decades under erosion conditions. The main rock cover should be divided into two categories: nickel chromium alloy and nickel chromium aluminum alloy. Hastelloy alloy has good corrosion resistance and thermal stability, and is widely used in aviation, chemical fields, and other industries.
