PH13-8Mo鋼的突出特點(diǎn)是，除高的強(qiáng)度外，還具有優(yōu)良的斷裂韌性，良好的橫向力學(xué)性能和在海洋環(huán)境中的耐應(yīng)力腐蝕性能。 一般來說，PH13-8Mo鋼的耐蝕性優(yōu)于1Cr13 和1Cr17Ni2(431)馬氏體不銹鋼；與17-4和15-5鋼相比，由于添加了鉬，耐點(diǎn)蝕性能更佳。和其他沉淀硬化不銹鋼一樣，在完全硬化狀態(tài)具有最佳耐蝕性。 盡管在苛刻的試驗(yàn)條件下，PH13-8Mo鋼在低于565℃的各種溫度時效對氫脆有些敏感，但實(shí)際使用中氫脆破裂事故卻很少見。在595℃以上的溫度時效，對氫致裂紋是免疫的。此外，在
