摘要
本文介绍了Q系列结构钢标准与国际(ISO)标准接轨后,其实质内容较旧标准有了很大的变化,取消了使用三十余年的老钢号A3、B2、16Mn等。新标准的钢号直接反映钢材最小屈服点数值,使用起来既方便又直观。但由于人们还是用老概念来理解和运用新标准而产生差错。提出对新标准的推广应做好深入细致工作,真正发挥新标准的优越性。
After linked with international ISO Standard, Q series constructional steel standard has great changes comparing to the old one. The old grade of steel such as A3, B2, 16Mn etc. have been canceled. The new standard grade of steel is directly indicated minimum yield point value. But people guided by old concept will use the new standard wrongly. The author proposes to use the new standard widely in order to exert its superiority.
