Stainless steel pipe is a hollow strip of round steel, which is widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural components. In addition, when the bending and torsional strength are the same, the weight is light, so it is also widely used in the manufacture of mechanical parts and engineering structures. Also used to produce a variety of conventional weapons, barrels, shells and so on.

What are the performance indexes of the square tube?we are round steel pipe exporter.

The square tube has a seamless square tube and a welded square tube. The seamless square tube is formed by extruding a seamless tube into a square shape.

1. Analysis of performance indicators of square tubes - plasticity

Plasticity refers to the ability of a metal material to undergo plastic deformation (permanent deformation) under a non-alternating load without damage to the shape structure.

2. Analysis of performance index of square tube - hardness

Hardness is an indicator of the hardness of a material. At present, the most commonly used method for measuring hardness in production is to measure the indentation hardness method, which is pressed into the surface of the metal material to be tested under a certain load by a high-hardness indenter of a certain geometry, and is determined according to the degree of indentation of the material by the indenter. Its hardness value.

Commonly used methods are Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) and Vickers hardness (HV).

3. Square tube performance index indicator - fatigue

The performance indicators discussed above, such as strength, plasticity, and hardness, are all mechanical properties of the metal under static load. In fact, many machine parts work under alternating or cyclic loads, under which metal parts can fatigue.
