As the name suggests, it is a square-shaped tube, many kinds of materials can be formed into a square tube body, it media, what for, where, most of the square tube to the majority of steel tubes, after unpacking, flattening, curling, welding to form a round tube, and then from the round tube rolled into a square tube and then cut into the required length. Usually 50 square tubes per package are in stock with large specifications mostly in 10*10*0.8-1.5~~500*500*10-25, square tubes are divided into structural square tubes, decorative square tubes, construction square tubes, mechanical square tubes, etc. according to the usage.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Square tubes is a hollow square section light thin-walled steel pipe, also known as steel refrigeration bending profile. It is Q235 hot-rolled or cold-rolled strip or coil for the base material by cold bending process forming and then high-frequency welding made of square cross-sectional shape size of the section steel. Hot rolled extra thick wall square tube in addition to wall thickness thickening, its corner dimensions and edge straightness are up to or even exceed the level of resistance welding cold forming square tube.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Plasticity<\/p>

Plasticity is the ability of a metallic material to produce plastic deformation (permanent deformation) under load without damage.<\/p>

Hardness<\/p>

Hardness is a pointer to the degree of hardness or softness of a metallic material. The most commonly used method for determining hardness in production is the indentation hardness method, which uses an indenter of a certain geometry to press into the surface of the tested metal material under a certain load and determines its hardness value according to the degree of being pressed into it.<\/p>

Commonly used methods are Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) and Vickers hardness (HV) methods.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Fatigue<\/p>

The strength, plasticity and hardness discussed earlier are all pointers to the mechanical properties of the metal under static load. In fact, many machine parts work under cyclic loads, and under such conditions the parts produce fatigue.<\/p>

Impact toughness<\/p>

The load acting on the machine part at a large speed is called impact load, and the ability of the metal to resist damage under impact load is called impact toughness.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Strength is the performance of a metal material to resist damage (excessive plastic deformation or fracture) under a static load. As the load is in the form of tensile, compression, bending, shear, etc., so the strength is also divided into tensile strength, compressive strength, bending strength, shear strength, etc.. There is often a certain connection between the various strengths, the use of the general tensile strength as the most basic strength pointer.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
