低活化铁素体钢（RAFS）已被选为ITER试验包层模块（TBM）的各种包层系统的结构材料。在评价作为包层系统结构部件的铁素体钢的综合性能时，每个包层系统都有独特的问题和共同的问题。每个系统的独特问题之一是铁素体钢与冷却剂材料的兼容性。本文综述了铁素体钢在热水、超临界加压水、湿空气、Pb-17 Li、锂和Flibe中不同温度下的腐蚀速率。考虑到合金设计，已经做出了改善耐腐蚀性的努力。氧化钇的分散是有效的，以提高耐腐蚀性的RAFS。RAFS与热水、Pb-17 Li、锂和Flibe的兼容性被认为对于TBM应用来说足够好。液态金属脆化（LME）被认为是RAFS用于锂系统的关键问题。从兼容性的角度来看，DEMO及以后的几个问题。
The reduced activation ferritic steel (RAFS) has been selected as structural material for a variety of blanket systems for ITER test blanket modules (TBM). In the evaluation of integrated performance of ferritic steels as structural components of blanket systems, there are unique issues as well as common issues for each blanket system. One of the unique issues for each system is the compatibility of ferritic steels with the coolant materials. The corrosion rate of ferritic steels in hot water, super critical pressurized water (SCPW), humid air, Pb–17Li, lithium and Flibe at various temperatures is reviewed in this work. Efforts to improve corrosion resistance have been made, taking the alloy design into account. A dispersion of yttria was effective to improve corrosion resistance of a RAFS. The compatibilities of RAFSs with hot water, Pb–17Li, lithium and Flibe are considered to be good enough for the TBM applications. The liquid metal embrittlement (LME) is considered to be a critical issue for the utilization of RAFSs for the lithium systems. Several issues towards DEMO and beyond are shown from the compatibility point of view.
