超纯超细晶粒钢是指杂质含量小于100ppm，晶粒尺寸在13级左右的工程结构用钢，这种钢的强度比传统的同成分的钢材强度要高一倍以上，而韧性保持不变。
Super pure and super fine crystal steel is the structural steel which contains impurity less than 100 ppm , crystal grain size about 13 rd grade , which has two times higher strength than traditional ones , but the same toughness .
