摘要
分析了石钢棒材个别炉次As、Sn>0.03%含量偏高产生的原因,比较了几种棒材As含量高的炉次与As<0.02%炉次的表面质量、抗拉强度、屈服强度、延伸率,对35CrMo钢裂纹及周围的Sn、As含量进行了分析。
It is analyzed the reason for As and Sn content in bar steel occasionally being larger than 0.03 percent in some heats,compared surface quality,tensile strength,yield strength and elongation between several high-As-content heats and other heats having As lower than 0.02 percent,analyzed the cracks on 35CrMo steel and content of As and Sn round the cracks.
