According to foreign media reports, despite the impact of the coronavirus epidemic, most German screw Q310GNH corten steel plate steel producers still maintain a good level of production. This is in sharp contrast to the situation in other European countries and Germany's domestic steel mills, which are suffering from a slowdown due to the spread of the epidemic. Lotter kummatt Stahl, a local distributor, told customers on its website: "there is no reason at present to believe that German steel mills such as Riva and ferralpi are no longer able to serve the Q310GNH corten steel plate market due to the impact of the closure of local steel mills in Italy.
Slow heating, preheating and other balanced heating methods can be used to reduce the heat treatment deformation of wear-resistant composite plate. Correct heat treatment process and reasonable tempering heat treatment process are also effective methods to reduce the deformation of wear-resistant composite plate. There are many reasons for the deformation of wear-resistant composite plate, Q310GNH corten steel plate. We only need to master the deformation law and analyze the reasons. The deformation of composite wear-resistant plate, Q310GNH corten steel plate can be alleviated and controlled.
