不銹鋼軸承系列產(chǎn)品介紹
不銹鋼軸承和普通軸承相比,普通鋼軸承無(wú)法滿(mǎn)足的情況下,可根據不同工況選擇相應的不銹鋼軸承,不銹鋼軸承具有獨特的使用性能,適應環(huán)境廣,耐酸堿、耐腐蝕、可在海水、河水、蒸餾水、稀硝酸、海洋性氣候、蒸汽等腐蝕介質(zhì)中工作。并有耐溫的特性,可在-253°~350°工作溫度范圍內使用。
KOVE軸承常用來(lái)制作不銹鋼軸承的材料有:SUS440C、SUS304、SUS316L等。SUS440C 為馬氏體不銹鋼,SUS304、SUS316L為奧氏體不銹鋼。奧氏體不銹鋼因其不可淬火,硬度上比較差,此類(lèi)材料的軸承只適用于低速及輕負荷場(chǎng)合中適用。奧氏體不銹鋼具有無(wú)磁性及耐腐蝕性能。
