Quenching is a common heat treatment process. It is the metal heat treatment process in which the what is gb t 4171 q355nh weather steel for welded structure metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between what is gb t 4171 q355nh weather steel for welded structure strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.

Weathering steel plate for welding structure is made by adding metal materials such as chromium, molybdenum, titanium and vanadium to ordinary molten steel. The addition of these materials can form a protective film on the steel surface, which can resist weathering corrosion for a long time. The advantages of weathering steel plate for welding structure: It has very good welding performance and weather resistance, and is widely used in railways, bridges and other areas that need to be exposed to the atmosphere for a long time. Disadvantages of weathering steel plate for welded structure: It has very high requirements on the production process, and the poorer technology can not produce good weathering steel plate, what is gb t 4171 q355nh weather steel for welded structure.
