我国将加快推广钒钛钢筋的步伐微合金４ＤＯＭＰ。新见级钢筋是“六五”、“七五”期间国家科技攻关获得的重要成果之一。这类钢筋具有良好的抗震性能、强度高、焊接性能好，可节省钢筋用量１０％～１５％，在国际上早已广泛使用，且用量较大。国内已具备广泛应用的条件。... China will speed up the pace of promotion of vanadium titanium steel 4DOMP. New-level steel reinforcement is one of the important achievements made by the state in scientific and technological research during the “Sixth Five-Year Plan” and “Seventh Five-Year Plan”. Such rebars have good seismic performance, high strength, good welding performance, can save 10% ~ 15% of the amount of steel, has long been widely used in the international community, and a larger amount. The country already has a wide range of application conditions. ...
