　　FeVN is a new type vanadium nitride alloy additives, its performance is better than FeV and VN, widely used in high strength rebar, pipeline steel,shape steel (H steel,I-steel, U-steel,angle steel),thin slab casting and rolling high strength steel strip, non-quenched and tempered steel,high-speed tool steel and so on.
　　Its specific gravity can reach 5.0g/cm³ up, so the absorptivity is more higher than adding VN(specific gravity is about 3.5), FeVN recovery over 95%, its absorptivity on average more than 3%-5% than VN, performance is more stable, it has better effects on refining grain and improving strength ,tenacity,ductility. FeVN V/N is about 4.0, is ideal Vanadium nitride alloy additives .
　　A mass of practical data shows, under the synthesized mechanical properties conditions such as the same strength, tenacity,ductility and thermal fatigue resistance etc, the fluctuation value of mechanical properties is lower than adding others vanadium alloy steel, and the minimum value of mechanical properties is higher. It can save 30-40% V than added others FeV, save over 10% V than added VN, reduce the steel cost, so wildly welcomed by user.
　　The process of adding FeVN is the same as plain carbon steel, the operation simple, easy to control, else it can eliminate steel strain aging.
