The thickness of the wear-resistant layer is uniform and the surface is smooth. The flatness of the whole wear-resistant steel plate is equivalent to that of the ordinary carbon steel plate, q355nh weather resistant steel. There is a stress release crack on the surface of the wear-resistant layer, which only exists in the hardfacing layer and does not extend into the matrix. The stress release crack can greatly reduce the residual stress and deformation of the matrix during the surfacing process, thus avoiding the reduction of the matrix strength and not affecting the service performance of the wear-resistant steel plate.
In 2018, one of our India customers visit Zhengzhou office building and work shop to discuss carbon steel Q235B grind plate technical request. They have strict surface and thickness tolerance, and they also request UT and MT for testing for Q235B grind plate. As a result, they purchase 179 tons as trial order for first cooperation. After using the gind plate, the India customer has good comment on our q355nh weather resistant steel quality. Till now, we keep exporting around 100 tons per month as regularly.
