本规范涵盖标称直径小于等于1 1/2英寸（38毫米）的棒材和线材形式的耐腐蚀和耐热工作强化镍合金。这些产品通常用于零件，如紧固件，在沉淀热处理后，要求室温最低抗拉强度为220 ksi（1517 MPa），最高使用900mDF（482mDC），抗氧化性高达1800mDF（982mDC），但使用不限于此类应用。

This specification covers a corrosion and heat resistant work strengthened nickel alloy in the form of bars and wire, 1 1/2 inches (38 mm) and under in nomial diameter.These products have been used typically for parts, such as fasteners, requiring a room temperature minimum tensile strength of 220 ksi (1517 MPa) after precipitation heat treatement for use up to 900 \mDF (482 \mDC) and having oxidation resistance up to 1800 \mDF (982 \mDC), but usage is not limited to such applications.
