What are the advantages of cold-rolled seamless steel pipe?
Date:2024-04-06
Seamless steel pipe can be divided into low carbon structural steel, alloy structural steel, alloy structural steel, common form with hot-rolled seamless steel pipe and cold-rolled seamless steel pipe and cold drawn seamless steel pipe.Usually after heat treatment of seamless steel pipe, cold-rolled seamless steel pipe in the heat treatment much more complicated than the hot-rolled seamless steel pipe.Cold- rolled seamless steel pipe and cold drawn seamless steel pipe is not in continuous production, The surface quality and dimensional accuracy of cold-rolled seamless steel pipe is better than that of hot-rolled steel pipe.
Cold rolled steel belongs to low carbon steel, because the carbon content is low, plasticity is good, can be cold rolled.In quality, cold rolled plate surface quality is better than hot rolled plate, cold rolling is the steel rolling process does not need to be heated to the material, or heated to the recrystallization temperature of the material.
The advantages of the cold-rolled seamless steel pipe is that the casting structure of the ingotI is destroyed, the defects of the microstructure are eliminated, The steel structure is compact and the mechanical properties are improved.
