APPLICATION OF VN12 ALLOY IN V-N MICROALLOYED STEEL
-
摘要: 通过在 20MnSiV、16MnV钢中,加入钒铁合金VFe(51.6%V)及美国钒公司提供的专利产品富氮钒合金VN12(80 %V,12 %N)的对比试验,研究了钒、氮复合微合金化对钢的力学性能的影响。与使用FeV(51.6%V)相比,采用富氮钒合金微合金化时,因钒用量的减少使得其技术经济性更加显著。Abstract: The effect of vanadium-nitrogen combined microalloying on the mechanical properties of 20MnSiV and 16MnV microalloyed steels was investigated through the contrast tests of adding V-Fe(51.6%V) or nitrogen enriched vanadium alloy VN12(American priority product,80%V,12%N),into 20MnSiV and 16MnV steels.Compared with VFe(51.6%V),microalloying with nitrogen enriched vanadium alloy VN12 have good economical benefits due to vanadium saving.
