Abstract

The invention relates to a production method of a partially-etched precision stainless steel strip, which comprises the following steps: semi-finish rolling; degreasing, washing and drying; solution heat treatment; tension rewinding; finish rolling; degreasing, cleaning and drying; micro extending, straightening and bundling. Due to the implementation of the technical scheme of the production process, the product has high thickness tolerance precision, low fluctuation, smooth surface, uniform surface roughness and no surface color difference. The plate is flat, has stable mechanical performance, is not easy to deform after being partially etched and can met the needs of producing the intelligent mobile phones in the communication industry.

Description

technical field [0001] The invention relates to the field of precision stainless steel strips, in particular, the invention relates to a semi-etched precision stainless steel strip, its production process and its application. Background technique [0002] Strip steel is a common metal product. Precision stainless steel strip is a kind of steel strip with high technical content. It can not only have precise dimensions, but also can guarantee the required mechanical performance indicators. The thickness of the finished steel strip can be as thin as 0.02mm, and the width can reach 1250mm; Hardness (Vickers) can be controlled in the range of 135-600. [0003] Precision stainless steel belt (generally refers to products with a thickness less than 0.5mm) is widely used in industries with special needs such as information technology, computers, auto parts, medical treatment, metal hoses, semiconductors, etc., and is a high value-added product. Therefore, the production of precisi...
