上海钢铁研究所研制的照相机用高精度不锈钢带,日前已进行技术鉴定。4种不同交货状态、56种尺寸规格的SZ304不锈钢带的尺寸精度、力学性能、外观质量和单卷重量全部达到了进口材料的实物水平,填补了国内高档照相机用高精度不锈钢带的空白。高精度不锈钢带是制造高级照相机结构件和弹簧件的必要材料。上海照相机总厂从日本美能达公司引进X-300照相机生产流水线,由于它对不锈钢带的尺寸精度、力学性能、外观质量和单卷重量要求非常严格,国内材料尚不能满足要求,只得依赖进口。为了促进国产化,上海钢铁研究所按照日本美能达公司的标准和实物质量经一年多的研制,已向上海照相
Shanghai Institute of Iron and Steel developed by the camera with high precision stainless steel, has been carried out technical appraisal. The dimensional accuracy, mechanical properties, appearance quality and single-roll weight of SZ304 stainless steel belt of 56 different sizes and delivery conditions in 4 different delivery states all met the physical level of imported materials, filling in the blank of high-precision stainless steel belt for domestic high-end cameras. High-precision stainless steel belt is the necessary material for the manufacture of advanced camera structures and spring elements. Shanghai Camera Factory introduced X-300 camera production line from Minolta Company of Japan. Because of its strict requirements on the dimensional accuracy, mechanical properties, appearance quality and weight of stainless steel strip, the domestic materials can not meet the requirements and have to rely on import. In order to promote localization, Shanghai Institute of Iron and Steel in accordance with Japan’s Minolta company’s standard and physical quality after more than a year of research and development, has been to Shanghai
