Abstract:

This chapter reviews experimental studies of the hydrogen embrittlement of high strength steels. The focus has been on six types of steel, having distinctly different microstructures. The six steel types are the low alloy steels, high toughness secondary hardening steels such as AF1410, hot work die steels, martensitic secondary hardening stainless steels, maraging steels and precipitation strengthened martensitic stainless steels. The susceptibilities of these classes of steel to hydrogen embrittlement as measured by the effects of hydrogen on fracture initiation and subsequent crack growth are discussed when the steels are tested in hydrogen gas, when the hydrogen has been introduced by charging and when the hydrogen embrittlement is associated with stress corrosion cracking in distilled water or salt water.

    For instance, quench and tempered (Q & T) martensite structures are good candidates for various structural applications. However, the ingress of hydrogen, even in parts per million (ppm) levels, from service environments, or during manufacturing, can significantly deteriorate the performance of these materials [4–6]. Additionally, the complex microstructure of these materials involving various H trap states such as dislocations, precipitates, different microstructural boundaries such as grain boundary (GB), packet boundary (PB) etc. increases the difficulties of modeling and prediction.

    As can be observed from Fig. 5, the HE index for 4340L and 4340 is approximately twice than that of 4140. The NFS% in case of 4340 is the lowest while it is maximum for 4140, which can be attributed to the fact that 4340 has the highest strength (both yield and tensile) and hardness [1,16]. However, the Q & T steels 4340L and 4140 have similar hardnesses but significantly different NFS% values, suggesting that strength is not the only consideration in the determination of HE susceptibility in this case.
