the high mn steel caustic embrittlement cracking was distinct in corrosion. with increasing corrosion time the impact toughness of high mn steel obviously decreased.
随着热强堿腐蚀时间的延长,高锰钢的沖击韧度明显降低,堿脆开裂是造成高锰钢沖击韧度下降的主要原因。
amine liquid corrosion caustic embrittlement under high temperature especially.
胺液腐蚀,特别是高温时堿脆。
with an increase of the chromium content in the cast steel, active dissolving corrosion increased, however, tendency of caustic embrittlement cracking decreased.
