Seamless steel tube hardness testing

Press release from: Hunan Standard Steel Co., Ltd

The hardness test is to slowly press a hard indenter into the surface of the sample under specified conditions, and then test the depth or size of the indentation to determine the hardness of the material. Hardness test is a simple, rapid and easy-to-implement method in material mechanical property test. The hardness test is non-destructive, and there is an approximate conversion relationship between the material hardness value and the tensile strength value. The hardness value of the material can be converted into the tensile strength value, which has great practical significance. Since the tensile test is inconvenient to test, and the conversion from hardness to strength is convenient, more and more people only test the hardness of the material and less test its strength.

The hardness of seamless steel tubes is generally measured by three hardness indicators: Brinell, Rockwell and Vickers.

1. Brinell hardness
In the seamless steel tube standard, the Brinell hardness is widely used, and the hardness of the material is often expressed by the indentation diameter, which is both intuitive and convenient. However, it is not suitable for steel pipes of harder or thinner steel.

2. Rockwell hardness
The Rockwell hardness test of seamless steel tubes is the same as the Brinell hardness test, which is an indentation test method. The difference is that it measures the depth of the indentation. Rockwell hardness test is a widely used method, among which HRC is second only to Brinell hardness HB in steel pipe standards. Rockwell hardness can be used to measure metal materials from extremely soft to extremely hard. It makes up for the inadequacy of the Brinell method. It is simpler than the Brinell method, and the hardness value can be read directly from the dial of the hardness machine. However, due to its small indentation, the hardness value is not as accurate as the Brinell method.

3. Vickers hardness
The Vickers hardness test of seamless steel tubes is also an indentation test method that can be used to determine the hardness of very thin metal materials and surface layers. It has the main advantages of Brinell and Rockwell methods, and overcomes their basic shortcomings, but it is not as simple as the Rockwell method, and the Vickers method is rarely used in steel pipe standards.

5 common defects and solutions of square tube electroplating
Today, let's talk about the corresponding solutions for five common defects in square tube electroplating. 1. The surface thickness is uneven When the pH of the plating solution is too high, and the wetting agent is too much, the wetting agent is easy to interact with Ni2+ to generate insoluble compounds, which are randomly adsorbed on the surface of the square tube, resulting in uneven thickness of the coating. To solve this

Carbon steel seamless tube vs Stainless steel seamless tube
The difference between carbon steel seamless tube and stainless steel seamless tube mainly refers to the difference in design rules between carbon steel and stainless steel, which means that the design rules of these two types of steel cannot be used in common. These differences are summarized as follows: Carbon steel 1. Ordinary steel is carbon steel, that is, iron-carbon alloy. According to the level of carbon content, it is divided into
