技术领域
本发明涉及一种不锈钢处理方法，具体涉及供一种提高不锈钢机械性能的处理方法。
背景技术
机械性能是金属材料的常用指标的一个集合。在机械制造业中，一般机械零件都是在常温、常压和非强烈腐蚀性介质中使用的，且在使用过程中各机械零件都将承受不同载荷的作用。不锈钢板在载荷作用下抵抗破坏的性能，称为机械性能(或称为力学性能)。不锈钢板使用性能的好坏，决定了它的使用范围与使用寿命，不锈钢板的机械性能是零件的设计和选材时的主要依据，外加载荷性质不同(例如拉伸、压缩、扭转、冲击、循环载荷等)，对不锈钢板要求的机械性能也将不同。常用的不锈钢板机械性能包括：屈服强度、抗拉强度、伸长率、断面收缩率、冲击功等。
发明内容
为解决现有不锈钢板存在的缺点，本发明的目的在于提供一种提高不锈钢机械性能的处理方法。
