Advance in Structural Steel

Weng Yuqing

Strategic Study of CAE 2002, Volume 4, Issue 3, Pages 48-53

Abstract:

Advance on “Ultra Steel”，which is characterized by fine grained microstructure，is described in this paper. Progress has been made in this field in China. Yielding strength increases from 235 Mpa to 420〜 470 Mpa while elongation increases from 26% to 29% 〜34% for plain carbon steels. The high strength steel with anti-delayed fracture function has been developed and its pilot testing has been successfully finished in IVECO Auto Com. with 13.9 grade.
