A513 Steel Square Tubing, It's a name for a square tube, which is a tube of equal length. It is made of strip steel after processing and rolling. Generally, the strip is unpacked, leveled, crimped and welded into a round tube, which is rolled into a square tube and then cut into the required length. Usually 50 sticks per pack. A513 Steel Square Tubing, There are seamless and weld points, seamless square tube is the seamless tube extrusion molding.

Exponential performance analysis of square tubes - plasticity Plasticity refers to the ability of a metal material to produce plastic deformation (permanent deformation) without damage under load. 2. Performance index analysis of square tube - hardness Hardness is a gauge of how hard or soft a metal material is. At present, the most commonly used method to determine hardness in production is the indenter hardness method, which is to use a certain geometric shape of the indenter head under a certain load into the surface of the tested metal materials, according to the degree of the indenter to determine its hardness value. Commonly used methods are Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) and Vickers hardness (HV) and other methods. 3. Performance index analysis of square tube - fatigue The strength, plasticity, and hardness discussed above are indicators of the mechanical properties of metals under static loading. In fact, many machine parts are operated under cyclic loads, and fatigue can occur under these conditions. 4. Performance index analysis of square pipe - impact toughness The load acting on the parts at a high speed is called impact load, and the ability of metal to resist damage under impact load is called impact toughness. 5. Square pipe performance index analysis - strength square steel pipe, thick wall square steel pipe, large diameter square steel pipe, seamless square steel pipe, low alloy square steel pipe, 135*135*10 square steel pipe, tower crane square steel pipe, Q345B low alloy square steel pipe, 20# seamless square steel pipe Strength is the ability of a metal material to resist failure (excessive plastic deformation or fracture) under static loading. Due to the mode of loading in the form of stretching, compression, bending, shearing, so the strength is also divided into tensile strength, compressive strength, bending strength, shear strength and so on. There is often a certain connection between various strengths, and tensile strength is generally used as the most basic strength pointer.
