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型钢进行耐腐蚀性能检测。试验采用72小时的循环周浸试验，试样采用60*40*4mm尺寸，每组分别取5块试样和5块对比样，通过计算两种试验钢的腐蚀前后重量差值，对比两种材料的腐蚀速率。

The data set is mainly used to test the corrosion resistance of 99mm hot rolled H-beams with flange thickness produced by Maanshan Iron and Steel Co., LTD. Seventy-two hours of cyclic immersion test was used in the test, and the size of the samples was 60*40*4mm. 5 samples and 5 contrast samples were taken from each group, respectively. The corrosion rate of the two materials was compared by calculating the weight difference between the two test steels before and after corrosion.
