奧氏體的英文表述為“Austenite”，字母A即為Austenite的簡(jiǎn)寫(xiě)?！?”表示奧氏體不銹鋼組類(lèi)第四種材料，是一種約定俗成的表示方式。因此，“A4”表示的是奧氏體不銹鋼組類(lèi)第四種材料。?2.?“80”的含義? “80”表示緊固件的機(jī)械性能，類(lèi)似于碳鋼螺栓的“8.8級(jí)”或者?碳鋼螺母的“8級(jí)”。是緊固件標(biāo)準(zhǔn)規(guī)定機(jī)械強(qiáng)度的十分之一，表示螺栓的抗拉強(qiáng)度為＞800Mpa或者保載強(qiáng)度能夠達(dá)到碳鋼8級(jí)螺母要求。</p><p>
