Hydrogen Embrittlement on 2.25Cr-1Mo Steel With Ferritic-Bainitic & Martensitic Microstructures

Abstract

In this paper, effect of hydrogen diffusion on 2.25Cr-1Mo steel with ferritic-bainitic and martensitic microstructure has been investigated. Hydrogen embrittlement of this steel was investigated by doing experimental such as delayed fracture and slow strain rate tests. Result of this research was showed that the steel with martensitic  microstructure strongly affected by hydrogen diffusion and was embrittled. But same steel with ferritic-bainitic  microstructure, even at high level of  hydrogen diffusion , has not show any embrittlement. Other experiments showed that , if martensitic microstructure steel will be remained on ambient temperature for above one week, effect of hydrogen diffusion  will be disappear. In this paper hydrogen embrittlement of 2.25 Cr-1Mo steel will be discussion
