| The nitric acid/hydrofluoric acid bath (Formula 3) must be used with care. Nickel-chromium and Ni-Fe-Cr alloys are subject to intergranular attack in this solution if they have been sensitized by heating in, or slowly cooling through, the 540 to 760 °C (1000–1400 °F) temperature range. Time in the bath should be kept to a minimum, and bath temperature must not exceed 50 °C (125 °F). Stress-relieved and age-hardened material can also be sensitive to intergranular attack if the heat treatment involved exposure to sensitizing temperatures. |

| The nitric acid/hydrofluoric acid bath (Formula 3) must be used with care.对硝酸/氢氟酸浴(方程式3)必须小心使用。 Nickel-chromium and Ni-Fe-Cr alloys are subject to intergranular attack in this solution if they have been sensitized by heating in, or slowly cooling through, the 540 to 760 °C (1000–1400 °F) temperature range. 如果在540到760°C(1000 - 1400°F)温度范围受热或缓慢冷却而敏化，在这种溶液中镍铬和镍铁铬合金易于受到晶间腐蚀。Time in the bath should be kept to a minimum, and bath temperature must not exceed 50 °C (125 °F). 酸浴时间应该保持最小,浴温度不能超过50°C(125°F)。Stress-relieved and age-hardened material can also be sensitive to intergranular attack if the heat treatment involved exposure to sensitizing temperatures如果热处理涉及接触敏化温度，应力消除和经久硬化材料也可对晶间腐蚀敏感。 |
