“A4-80”是不銹鋼緊固件產(chǎn)品中常見的一種標(biāo)識，下面就為大家詳細(xì)介紹一下這個標(biāo)識**的含義。? 1.?什么是“A4”，A4這個稱謂從何而來？? 不銹鋼按照金相**特性來分，分為奧氏體不銹鋼、馬氏體?不銹鋼、鐵素體不銹鋼三個常規(guī)大類。? 奧氏體的英文表述為“Austenite”，字母A即為Austenite的簡寫。“4”表示奧氏體不銹鋼組類第四種材料，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第四種材料。?2.?“80”的含義? “80”表示緊固件的機(jī)械性能，類似于碳鋼螺栓的“8.8級”或者?碳鋼螺母的“8級”。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級螺母要求。A4-80和A4L-80螺絲都屬于奧氏體不銹鋼緊固件。江蘇質(zhì)量A4-80
