16Mn钢 Q345级角钢 V(N)微合金化 力学性能
16Mn鋼 Q345級角鋼 V(N)微閤金化 力學性能
16Mn강 Q345급각강 V(N)미합금화 역학성능
大规格角钢主要用于铁塔和建筑结构中.唐钢过去用16Mn钢生产Q345级别角钢,因供轧制用钢的内控标准化学成分窄(T16Mn钢%:0.18~0.20C,1.35~1.55Mn,Ceq≥0.41),致使供轧率仅为30%.通过V-N微合金化,开发了T16MnV(N)钢(%:0.14~0.20C,1.30~1.60Mn,0.05~0.09V,0.009~0.018N),V(N)微合金化显著提高了该钢的力学性能:σb 520~625 MPa,σs 395~465 MPa,δ5 24%~28%,冲击功43~96 J,并取得较高的经济效益.
