金属-板材-图片3-是拉差典型钢腐蚀速率
根据四个大气实验站 3 个月、 8 个月、 12 个月和 24 个月取样周期内典型钢种 Q345 碳钢、 400E、 450qNH、 420qNH、 Q345qNH 腐蚀速率变化规律,图3为是拉差大气实验站典型钢的腐蚀速率
Metal plate picture 3 is the corrosion rate of typical steel in Sriracha
According to the change law of corrosion rate of typical steel Q345 carbon steel, 400e, 450qnh, 420qnh and q345qnh in the sampling period of 3 months, 8 months, 12 months and 24 months in four atmospheric experimental stations, Fig. 3 shows the corrosion rate of typical steel in differential atmospheric experimental station
