摘要
针对延伸率低的Q2 3 5B中板,通过对拉伸试样的化学成分、断口、非金属夹杂物和金相组织等理化检验,分析了造成试样层状断口、中板延伸率低的原因。
From physical and chemical test for chemical components, fracture surface, non-metal inclusion and microstructure of tension sample, the reason of low elongation for Q235B medium plate is analyzed and some measures proposed.
