High yield strength cold rolled weathering steel strip properties

In order to improve the cold rolled weathering steel strip corrosion resistance and decoration of steel, it is an important content of steel production method to plating or coating a protective layer on the surface of plastic processed steel. The material of protective layer is divided into metal and non-metal. The metal protective layer adopts the methods of electroplating, hot plating and chemical plating. The main cold rolled weathering steel strip coating metals are zinc, tin, copper, aluminum, chromium, etc., of which zinc plating and tin plating are the most common. Taking cold rolled weathering steel strip sheet metal as an example, there are many hot-dip galvanizing methods used in sheet metal galvanizing. Continuous hot-dip galvanizing is one of the main galvanizing methods used in the world.

cold rolled weathering steel strip, Q345 steel has good comprehensive mechanical properties. Q345 steel also has acceptable low temperature performance, good plasticity and weldability. Q345 steel can be used as structures, mechanical parts, building structures and general metal structures bearing dynamic loads such as medium and low pressure vessels, oil tanks, vehicles, cranes, mining machinery, power stations and bridges. Q345 steel can be used in hot rolling or normalizing state, and can be used in various structures in cold regions below - 40 ℃.
