國外同類型鋼種,有前蘇聯的15XM,美國牌號T12、P12,日本牌號STBA22、STPA22和德國牌13CrMo44等。
15CrMo鋼正常供貨狀態的顯微組織為鐵素體加珠光體,15CrMo鋼在工作溫度500℃-550℃範圍長期運行過程中,會產生珠光體的球化、合金元素在固溶體和碳化物間的再分配及碳化物相結構的改變,15CrMo鋼的熱強性能和力學性能隨著珠光體球化程度和固溶體是合金元素貧化程度的加大而逐漸降低,以致材質漸趨劣化甚至失效。因此,長期以來15CrMo鋼組織中珠光體球化程度常被廣泛用於判定該類鋼使用可靠性的重要判據之一。
合金管重量計算公式:
[(外徑-壁厚)*壁厚]*0.02466=kg/米(每米的重量)
