Weathering steel SPA-H corrosion test supplied by katalor

At present, weathering steel SPA-H is the leading product of katalor. In order to clarify the corrosion resistance of weathering steel SPA-H produced by katalor, this paper studied it by accelerated corrosion test method. The results of the SPA-H steel cycle infiltration corrosion test of weather resistant steel are shown in the figure below. It can be seen that under the accelerated corrosion test conditions of 72h, the weather-resistant steel SPA-H produced by katalor has the best corrosion resistance performance, which is significantly better than the weathering steel SPA-H produced by the A plant.

 Weathering steel SPA-H cycle infiltration corrosion test results

                                                                                                                                                       
(1) Under the conditions of accelerated corrosion test at 72h, the corrosion resistance of weather-resistant steel SPA-H produced by katalor is better than that of domestic A and B plants.
(2) High calcium, low sulfur, high titanium, a small amount of pearlite structure, which is beneficial to improve the corrosion resistance of SPA-H steel.
