    F5 不是鑄造的材料規格,而是高溫使用鍛造 Low Alloy Steel 材料的規格。

    依照 ASTM A182 (Standard Specification for Forged or Rolled Alloy and Stainless Pipe Flanges, Forged Fittings, and Valves and Parts for High-Temperature Service),其中有 F5 的材料規格,其 UNS 號碼為 K41545,屬於 5Cr1/2Mo 的等級。

    詳細的化學成分為: C 0.15%,Mg 0.30-0.60%,P 0.030%,S 0.030%,Si 0.05%,Cr 4.0-6.0%,Mo 0.44-0.65%

    詳細的機械性能為:Tensile Strength 70 ksi min [485 MPa min],Yield Strength 40 ksi min [275 MPa min],Elongation in 2 inch: 20% min,Reduction of Area 35% min.
