18CrMo4(1.7243)是一種在500~550℃下有較高的持久強(qiáng)度,溫度超過550℃時(shí),抗氧化性能變差,蠕變強(qiáng)度顯著降低的鋼。
執(zhí)行標(biāo)準(zhǔn): EN 10084-1998
●特性及適用范圍:
18CrMo4(1.7243)合金結(jié)構(gòu)鋼有良好的工藝性能和焊接性能,在500~550℃下有較高的持久強(qiáng)度。溫度超過550℃時(shí),抗氧化性能變差,蠕變強(qiáng)度顯著降低。長期處在500~550 ℃時(shí),18CrMo4鋼的熱強(qiáng)性降低,強(qiáng)度降低。18CrMo4用于制造510℃的高、中壓蒸氣導(dǎo)管、集箱以及管壁溫度為550℃的過熱器及鍛件。
