哈氏合金是一種鎳基耐腐蝕合金。

哈氏合金是一種費用昂貴、且耐酸性侵蝕特別強的一種合金質料，它的力學機能勝過不銹鋼質料幾十倍，能在侵蝕情況連續運用幾十年的光陰。主巖畝隱要分成鎳鉻合金與鎳鉻鉬合金兩大類。哈氏合金具有良好的抗腐蝕性和熱粗廳穩定性，多用于航空事業，化學領域等。

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.
