????????鋼球主要材質(zhì)主要有軸承鋼和不銹鋼兩大類，軸承鋼球的物理和力學(xué)性能在前天已經(jīng)給大家介紹，接下來(lái)是為大家介紹紅潤(rùn)泰鋼球廠的不銹鋼球材質(zhì)的性能。今天介紹的是不銹鋼球316，這種材質(zhì)生產(chǎn)的鋼球硬度HRC<=28，防銹能力和其他不銹鋼球相比，特別是4字開頭的不銹鋼，要高很多，但SUS316不銹鋼生產(chǎn)出來(lái)的鋼球，硬度偏低，滿足不了即要求防銹能力高，又有一定承載負(fù)荷的環(huán)境。用途：主要應(yīng)用與醫(yī)療器械、食品機(jī)械、化妝品配件、人體飾品、儀表儀器、化工、航空、航天、香水瓶、噴霧器、閥門、指甲油、手機(jī)電池等。
