铝型材挤压机用钢H13锻材的研制

Development of H13 Steel for Forgings of Aluminium Extrusion

东北特殊钢大连基地利用本身设备及技术优势,开发出一系列生产工艺,试制出满足北美压铸协会NADCA207优质钢标准要求的ф140-800mm锻造棒材,经过用户鉴定满足使用要求,特别是Ф600-800mm直径的棒材半径二分之一处的球化组织也完全满足该标准的要求,为技术上的一大突破。

Relying on its advantages in equipments and techniques, Dongbei Special Steel Dalian Bbase developed a series of production process and produced the Ф140-800mm forging steel bar meeting the North American Die Casting Association NADCA207 quality standard requirements. Customer identification shows that it meets the requirements, especially the spheroidized structure bar radius 1/2 with 600-800mm diameter also fully meets the standard requirements, which is a breakthrough in technology.
