本规范涵盖熔模铸件形式的耐腐蚀耐热钴合金。这些铸件通常用于涡轮叶片等零件，要求高强度高达1500 mDF（816 mDC），抗氧化性高达2000 mDF（1095 mDC），但用途不限于此类应用。暴露在高温下可能会导致该合金硬化；e、 例如，暴露在大约1475mDF（800mDC）下50小时。可能导致硬度高达45 HRC。

This specification covers a corrosion and heat resistant cobalt alloy in the form of investment castings.These castings have been used typically for parts such as turbine vanes requiring high strength up to 1500 \mDF (816 \mDC), and oxidation resistance up to 2000 \mDF (1095 \mDC), but usage is not limited to such applications.Exposure to elevated temperatures may cause hardening of this alloy; e.g., exposure at approximately 1475 \mDF (800 \mDC) for 50 hrs. may result in hardness as high as 45 HRC.
