重庆市黑色金属材料工业的可持续发展水平高于甘肃省黑色金属材料工业的可持续发展水平。

The degree of SD of ferrous material industry in Chongqing City was higher than that in Gansu Province .

用来做工具的主要材料可以被分为三大类：黑色金属材料，有色金属材料，非金属材料。

The principle materials used for tools can be divided into three major categories : ferrous material , nonferrous material , and nonmetallic material .

该技术已成功用于黑色金属材料，能明显提高工件的强度、耐磨性和尺寸稳定性，使工件使用寿命成倍提高，但该技术在有色金属方面的研究较少。

Cryogenic treatment has been successfully used in ferrous metal materials , to improve the strength , wear resistance and dimensional stability of workpieces .

甘肃省材料工业中以黑色金属材料工业的可持续发展水平最低，金属材料制品业的可持续发展水平最高；

Among the material industries in Gansu Province , the degree of SD of ferrous material industry was the lowest , the degree of SD of metal products industry was the highest .
