该数据集主要对马鞍山钢铁股份有限公司生产的99mm翼缘厚度规格热轧H型钢进行室温拉伸性能的检测，主要是表征材料在室温环境下断裂破坏的能力，是体现材料强度的重要指标。该试验检测是将试样在室温条件下加载应力拉断，期望获得屈服强度不低于460MPa的良好力学性能。

This data set mainly tests the tensile properties of 99mm hot rolled H-beams with flange thickness produced by Maanshan Iron and Steel Co., LTD at room temperature, mainly to characterize the material's ability to fracture at room temperature, which is an important indicator of material strength. This test is to test the specimen under the condition of room temperature loading stress tensile fracture, expected to obtain a yield strength of not less than 460MPa good mechanical properties.
