低溫鋼在石油氣深冷分離設(shè)備中，絕大部分的最低使用溫度為-110℃,個別設(shè)備中達-150℃,可分別采用低合金鋼、3～6％鎳鋼或 9％鎳鋼。在空氣分離設(shè)備中，最低工作溫度達-196℃,一般采用9％鎳鋼或奧氏體低溫鋼。工作溫度為-253℃的液氫生產(chǎn)、貯運設(shè)備，工作溫度為-269℃的液氦設(shè)備，均應(yīng)采用組織結(jié)構(gòu)穩(wěn)定的奧氏體低溫鋼。而某些特殊設(shè)備如超導(dǎo)磁體或超導(dǎo)電機，宜采用在工作溫度以下除有穩(wěn)定的奧氏體組織外,還要能保持極低磁導(dǎo)率(μ)≤1.01或更低）的鋼種。 一些具有較高低溫韌性的鐵鎳基和鎳基高溫合金如A-286、Inconel718、InconelX-750 等也常用于需要高強度的低溫設(shè)備上。
