方管有无缝和焊缝之分,无缝方管是将无缝圆管挤压成型而成。
Square pipe can be divided into seamless and welded seams. Seamless square pipe is formed by extrusion of seamless round pipe.

塑性是指金属材料在载荷作用下,产生塑性变形(永久变形)而不破坏的能力。
Plasticity refers to the ability of metal materials to produce plastic deformation (permanent deformation) without destroying under load.

硬度是衡量金属材料软硬程度的指针。目前生产中测定硬度方法最常用的是压入硬度法,它是用一定几何形状的压头在一定载荷下压入被测试的金属材料表面,根据被压入程度来测定其硬度值。
Hardness is the index to measure the degree of hardness and softness of metal materials. Pressure hardness method is the most commonly used method to measure hardness in production at present. It uses a certain geometric shape of the pressure head to press into the tested metal material surface under a certain load, and to measure its hardness value according to the degree of pressure.
常用的方法有布氏硬度(HB)、洛氏硬度(HRA、HRB、HRC)和维氏硬度(HV)等方法。
Common methods include Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) and Vickers hardness (HV).
