Peeling round steel is a high-precision round steel that has undergone heat treatment and can be immediately used to make shafts without the need for further processing; The matching general round steel refers to the round steel commonly used in engineering and construction. The quenching and tempering treatment of the supply is "quenching", and both the precision of the specifications and the materials are of average level.

Whether it is peeled round steel or round steel, its appearance is all circular, but the surface of cold drawn round steel is very smooth, with high precision specifications. Its physical properties are high because the high precision specifications can be applied immediately without processing. Cold drawing refers to the method of releasing tensile strength on both sides of a metal composite material, causing the raw material to undergo stretching deformation in a round steel; Cold drawing refers to the method of releasing pulling force at one end of the raw material, so that the raw material is pulled out according to a grinding tool hole, and the diameter of the grinding tool is smaller than that of the raw material.

Cold drawing processing causes raw materials to undergo not only stretching deformation but also extrusion forming deformation. Cold drawing processing is generally carried out in professional cold drawing machines. Raw materials processed by cold drawing have more stable characteristics than those processed by cold drawing. Cold drawing and cold drawing refer to the process of reducing the strength and improving the plastic deformation of round steel after quenching, and then processing it at room temperature using a pulling machine. Cold drawing is the process of reducing the strength and improving the plastic deformation of thick steel plates after quenching, and then processing it at room temperature using refrigeration.
