hrb400钢筋和hrb400e钢筋能相互替代吗?

  众所周知,我国钢铁工业经历了多年的风风雨雨,已经从快速发展阶段过渡到目前调整的薄弱阶段。产品的改进也有很大的变化。其中突出的是hrb400钢筋(三级螺纹钢筋)和hrb400e钢筋(三级抗震螺纹钢筋)。在建筑钢筋领域中,第三级螺纹钢筋的“支配”时间长,在使用领域中所占比例大。
  As we all know, China's iron and steel industry has experienced many years of ups and downs, and has transited from the rapid development stage to the weak adjustment stage. The improvement of products has also changed a lot. The most prominent ones are HRB400 steel bar (three-level threaded steel bar) and hrb400e steel bar (three-level seismic threaded steel bar). In the field of building reinforcement, the third-grade threaded steel bar has the longest "domination" time and the largest proportion in the field of use.
  近年来,hrb400钢筋已被hrb400e钢筋所取代。那么我们是否知道它们之间的区别和相同之处,是否可以用三级地震钢来代替三级地震钢呢?
  In recent years, HRB400 steel bar has been replaced by hrb400e steel bar. So do we know the differences and similarities between them, and can we use three-level seismic steel instead of three-level seismic steel?
  我们来看看他们的成绩,hrb400e hrb400“E”的视觉差异,近年来地震指数增加,建设高标准的“E”是指使用的抗震要求钢结构,其力学特性是衡量抗拉强度和屈服强度比不小于1.25,实测屈服强度和屈服强度比不大于1.30的规定的标准,而且大到总伸长不小于9%。这样的钢筋是目前建筑要求能够满足标准的品种,所以虽然三级螺杆式钢筋在其他等级市场上的要求是一样的,但这一关键抗震性能还不够,所以很多已被淘汰。两者主要相似之处在于,低屈服强度标准值为400MPa,设计值为360MPa。

  Let's take a look at their achievements. The visual difference of hrb400e HRB400 "E" has increased in recent years. The construction of high-standard "E" refers to the steel structure required for seismic resistance. Its mechanical characteristics are to measure the ratio of tensile strength to yield strength not less than 1.25, the ratio of measured yield strength to yield strength not less than 1.30, and the maximum elongation is not less than 9%. This kind of reinforcement can meet the requirements of the current building standards, so although the requirements of three-stage screw reinforcement are the same in other grades of the market, but this key seismic performance is not enough, so many of them have been eliminated. The main similarity between them is that the standard value of low yield strength is 400 MPa and the design value is 360 MPa.
  HRB400钢筋可用于一些无特殊要求的建筑工程中。那么今天的hrb400钢筋相关知识就介绍在这里,有更多的济南钢筋批发知识带给您,希望您多多关注我们的网站:http://www.jzqgc.com/
