Seamless square tube performance and characteristics
Main properties of seamless square tube
The first performance to talk about is plasticity, for the seamless square tube, the metal material can produce plasticity under the action of load, resulting in deformation, this deformation refers to a permanent deformation, generally will not be damaged by external force.
Secondly, let's talk about the hardness of the seamless square tube, you know, the hardness index of the steel tube material is also an indicator to measure the hardness of a certain metal material to a certain extent, and the hardness of the seamless square tube belongs to the higher one in all materials. Finally, the fatigue of seamless square pipe is similar to the two properties mentioned above, and the fatigue of seamless steel pipe is moderate.
Seamless square pipe main features:
The inner and outer walls of the seamless square tube are high precision, the tube has no oxide layer behind the heat treatment, the inner wall is high cleanliness, the square tube is under high pressure, the cold bending is not deformed, the flaring, flattening is not cracked, and can be used for various complex deformation and mechanical processing.
Calculation formula of square tube weight: 4* wall thickness *(side length - wall thickness)*0.00785
It can better improve the surface strength and wear resistance of seamless square tube, and carry out surface treatment of seamless square tube, such as surface layer, high frequency induction treatment, organic chemical heat treatment and so on.
Rectangular tube weight calculation formula: (circumference /3.14- wall thickness)* wall thickness *0.02466
Hot quenching specifies that the substrate is dominated by ferrite after treatment. Water spray or spray paint acrylic emulsion aqueous solution for refrigeration. The heat treatment temperature is in the middle of 300-500, and the strength is 30-40HRC, which can ensure the strength and wear resistance of the seamless square tube surface.
