15CrMoG 是GB5310-95钢号（对应的是世界各国广泛应用的1Cr-1/2Mo和11/4Cr-1/2Mo-Si型钢），其铬含量较12CrMo钢高，因此在500-550℃具有较高的热强性。当温度超过550℃时，其热强性显著降低，当其在500-550℃长期运行时，不产生石墨化，但会产生碳化物球化及合金元素的再分配，这些均导致钢的热强性降低，钢在450℃时抗松驰性能好。其制管和焊接等工艺性能良好。主要用作为蒸汽参数550℃以下的高、中压蒸汽导管和联箱、管壁温度560℃以下的过热器管等。其化学成分C0.12-0.18，Si0.17-0.37，Mn0.40-0.70，S≤0.030，P≤0.030，Cr0.80-1.10，Mo0.40-0.55；正回火态下强度水平σs≥235，σb≥440-640 MPa；塑性δ≥21。 我厂使用此钢小口径管主要用于低温过热器/再热器、包墙过热器等部件。此钢在伊朗炉（指单台）上所使用的部位为中温过热器（数量为5吨）、低温再热器（33吨）。
