Steel castings of this excellent material quality, has long been recognized by the industry. However, its production process is more complicated and cumbersome than other steel types, especially the welding link, which is the key.
When welding steel castings, quenching and tempering treatment is an indispensable step. This step can effectively stabilize the internal structure of steel and make the performance of heat-resistant steel better. Especially for martensitic heat-resistant steel, quenching and tempering treatment can give it excellent comprehensive mechanical properties and high temperature strength, so that it can maintain excellent performance in various extreme environments.
Although ferritic steel cannot be strengthened by heat treatment, it can also achieve a certain internal stress balance during the welding process. Before welding, annealing treatment is an indispensable step, which can effectively improve the quality of welding. Regardless of the type of cast steel, it needs to be welded in the as-cast state, which not only achieves better thermal deformation, but also ensures that the welded heat-resistant steel has higher strength and stability.
In short, although the welding process of steel castings is complicated, it is these fine steps that make the heat-resistant steel show its excellent performance in various harsh environments.
