中文摘要：采用S355J2W与S355J2结构钢进行组织性能试验。试验结果表明：S355J2W中Cu、Cr将对合金的耐侯性能起到至关重要的作用,并且S355J2W中S含量很低，冶金质量较高，夹杂物含量很少。S355J2W低温冲击韧性高于S355J2。
英文摘要：Analysing to S355J2W and S355J2 structural steels mechanical property.The results show that the alloy elements Cu,Cr in S355J2W paly a vital role in atmospheric corrosion resistance,and the content of alloy element S in S355J2W is very little, metallurgy quality is better, sulfid is little, and low temperature impact energy of S355J2W is better than S355J2.
