摘要
本文介绍了铬在钢中的作用和铬的强化机制,并选取四组福建三钢生产的HRB400E抗震钢筋样品进行高铬和低铬对比实验。实验表明,Cr改善了材料的淬透性,S回层厚度变大,提高了钢的硬度和抗拉强度。
This paper introduces the effect of chromium in steel and chromium strengthening mechanism, and select the HRB400 E reinforced sample four group Fujian steel production of high chromium and low chromium experiment. The experimental results show that Cr improves the harden ability of the material, the thickness of the S back layer increases, and the hardness and tensile strength are improved.
