【Abstract】 In order to produce high strength 460MPa reinforced bar which accord with the UK standard,the chemical composition and technology were designed by Jinan Iron and Steel Group Co. Practical production show that the products synthetical performances are good by V micro-alloying and recrystalization rolling technology. The element of V can not only increase the strength but also improve the elongation and the ration of strength and yield.更多还原
