Difference between ASTM A513 and ASTM A500 rectangular tubes

What is a rectangular tube? Rectangular tube is a long hollow steel material with a rectangular cross-section. They are typically made of steel, aluminum, or other metals and have a variety of uses and applications. When the bending and torsion strength are the same, the weight is lighter, so it is widely used in manufacturing mechanical parts and engineering structures. The difference between ASTM A513 and ASTM A500 rectangular tubes: ASTM A500 (also

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

Characteristics and advantages of precision carbon steel pipes

With the rapid development of the industrial field, the requirements for materials are becoming higher and higher. Especially in many high-precision jobs, precision carbon steel pipes have long become a very important material and enjoy a high reputation. Next, let's discuss the characteristics and advantages of precision carbon steel pipes. Characteristics of precision carbon steel pipes: Characteristic 1: Higher accuracy Precision carbon steel pipes have high processing accuracy and can be used to

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

Seamless steel tube hardness testing

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
