本规范涵盖了棒材、线材、锻件、机械管和锻件或镦头用库存的耐腐蚀耐热钢。这些产品通常用于涡轮转子、轴、叶片、叶片、定位销、法兰和配件等零件，这些零件在沉淀热处理后要求中等强度高达1300 mDF（704 mDC），抗氧化性高达1500 mDF（816 mDC），但使用不限于此类应用。

This specification covers a corrosion and heat resistant steel in the form of bars, wire, forgings, mechanical tubing, and stock for forging or heading.These products have been used typically for parts, such as turbine rotors, shafts, blades, vanes, dowels, flanges, and fittings, requiring moderate strength up to 1300 \mDF (704 \mDC) and oxidation resistance up to 1500 \mDF (816 \mDC) after precipitation heat treatment, but usage is not limited to such applications.
