摘要: Abstract This paper presents two high-strength steels composed of granular bainite microstructure that have higher extrinsic resistance to hydrogen embrittlement (HE) than conventional tempered-martensite steel, because the steel traps less steel. However, had lower intrinsic HE in becomes concentrated at microstructures martensite islands and retained austenite. The with sulfur showed better properties, S degrades grain-boundary strength. Since properties correspond is relevant industry, are suitable for applications environment.
