Compared with 12CrMoV steel, sa709gr50 asme bridge steel, 12Cr1MoVR pressure vessel steel has higher oxidation resistance and heat strength. The creep limit of this steel is very close to the endurance strength value, and it has high plasticity under the condition of long-term stretching; the steel has good manufacturability and weldability, but it needs to be preheated to 300 ° C before welding, and the stress needs to be removed after welding deal with.
In order to improve the sa709gr50 asme bridge steel 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 sa709gr50 asme bridge steel coating metals are zinc, tin, copper, aluminum, chromium, etc., of which zinc plating and tin plating are the most common. Taking sa709gr50 asme bridge steel 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.
