Production method of hard austenite stainless precision strip steel

The invention relates to a production method of hard austenite stainless precise strip steel, belongs to the technical field of production of hard strip steel, and solves the problem that an ultrathin material (the thickness is smaller than or equal to 0.03 mm) is difficult to roll at a low hardness grade (the deformation is smaller than or equal to 15%). The stainless steel is subjected to incomplete annealing at the temperature of 600-950 DEG C, the martensite transformation amount is controlled, the purpose of controlling the hard grade is achieved, sensitization of the stainless steel is avoided in a rapid cooling mode, a finished product meeting the requirement is obtained, and compared with a conventional hard material production process, the technological process is greatly simplified, and the cost is saved. 本发明涉及一种硬态奥氏体不锈精密带钢的生产方法，属于硬态带钢的生产技术领域，解决超薄料（厚度≤0.03mm）低硬度等级（变形量≤15%）难以轧制的问题，解决方案为：采用原料→成品轧制→不完全退火→拉矫→剪切→成品的工艺流程，将不锈钢在600-950℃的温度下进行不完全退火，控制马氏体转变量，达到控制硬态等级的目的，通过快速冷却的方式避免不锈钢的敏化，得到符合要求的成品，较常规硬态料生产的工艺
