Bake hardenable vanadium containing steel

摘要

The present invention refers to a rolled steel article consisting essentially of by weight percent: 0.0005 to less than 0.1 % carbon; between zero and up to 2.5 % manganese; between zero and up to 0.5 % aluminium; between zero and up to 0.5 % of a nitride forming element selected from the group consisting of boron, zirconium and titanium; between zero and less than 0.04 % nitrogen; between 0.005 and less than 0.6 % vanadium; between zero and up to 1.0 % silicon and between zero and up to 0.25 % phosphorus; with the balance being iron and inevitable impurities, characterized in that the ratio of vanadium to carbon is 10 or above. Moreover the application is directed to a method for producing the same.
