The invention relates to the technical field of stainless steel band manufacturing, and particularly discloses a manufacturing process of a precise high-elongation stainless steel band. The problems that when the hardness of a stainless steel coil of a traditional electronic product part is larger than 500 HV and the tensile strength is larger than 1500 Mpa, the ductility of the stainless steel coil is greatly reduced, and the brittleness of the stainless steel coil is increased are mainly solved, and the scheme mainly comprises the following steps of roller preparation, raw material preparation, multiple times of rolling, annealing softening, surface cleaning, withdrawal and straightening treatment, slitting testing and packaging. The stainless steel coil has the effect of improving the high ductility of the stainless steel coil at high strength. 本申请涉及不锈钢带制造技术领域，具体公开了一种精密高延伸不锈钢带的制造工艺。主要解决了传统的电子产品部件的不锈钢钢卷硬度＞500HV，抗拉＞1500Mpa时，它的延展性会大大降低，脆性增加的问题，其方案主要包括如下步骤：轧辊准备、原料准备、多次轧制、退火软化、清洗表面、拉矫处理、分切测试、包装。本申请具有提升不锈钢卷在高强度时
