Recently, Fangda Special Steel has successfully developed the new national standard HRB500 (E) high-strength straight steel bar, and all the performance indicators of the product meet the requirements of the new national standard GB/T1499.2-2018.
It is understood that HRB500 (E) steel bar needs to add more alloys to improve its strength than the old standard HRB400 (E) steel bar. If the composition and process design are unreasonable, it is easy to make the product performance and structure abnormal.
