Square pipe is a kind of square shape of the pipe, many kinds of materials can form a square pipe body, its medium in, what to use, where to use, most of the square pipe to steel pipe for the majority, mostly for structural square pipe, decorative square pipe, construction square pipe.
The square pipe has seamless and weld, seamless square pipe is the seamless round pipe extrusion molding.
Performance index analysis of square pipe -- plasticityPlasticity refers to the ability of metal materials under load to produce plastic deformation (permanent deformation) without failure.2. Performance index analysis of square pipe -- hardnessHardness is a measure of the hardness of metallic materials.At present, the most commonly used method to measure hardness in production is the incorporation hardness method, which USES a certain geometric head to press the metal material surface under a certain load to measure its hardness value according to the degree of incorporation.The commonly used methods include brinell hardness (HB), rockwell hardness (HRA, HRB, HRC) and vickers hardness (HV).
