| 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.對硝酸/氫氟酸浴(方程式3)必須小心使用。 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)溫度范圍受熱或緩慢冷卻而敏化，在這種溶液中鎳鉻和鎳鐵鉻合金易于受到晶間腐蝕。Time in the bath should be kept to a minimum, and bath temperature must not exceed 50 °C (125 °F). 酸浴時間應(yīng)該保持最小,浴溫度不能超過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如果熱處理涉及接觸敏化溫度，應(yīng)力消除和經(jīng)久硬化材料也可對晶間腐蝕敏感。 |
