Shandong Liaocheng Steel Tube Plant describes the difference between hot-rolled seamless steel tubes and cold-rolled seamless steel tubes. What is the difference between hot-rolled seamless steel tubes and cold-rolled seamless steel tubes? Usually, seamless steel tubes are not Cold Rolled Steel Strip hot-rolled seamless steel tubes. Small diameter, hot-rolled seamless steel tubes are often large diameter. The precision of cold-rolled seamless steel tubes, which can also involve Silicon Steel...
What is the difference between hot-rolled seamless steel tubes and cold-rolled seamless steel tubes? Is it generally said that seamless steel tubes are not Cold Rolled Steel Strip hot-rolled seamless steel tubes? Cold-rolled seamless steel tubes are often of small diameter, and hot-rolled seamless steel tubes are often large diameter. The precision of cold-rolled seamless steel tubes, which can incorporate Silicon Steel Core technology, is higher than that of hot-rolled seamless steel tubes,...

In the hot-dip galvanizing plate, the surface will often be distributed with small particles. These small particles not only make the galvanized steel surface rough, affecting the overall appearance, but are also harmful to use. The main reason for the formation of zinc particles is that the bottom slag is floated by excessive mechanical agitation, causing the zinc liquid to adhere to the surface of the galvanized sheet. Alternatively, the temperature of the zinc liquid may be too high, causing...
Shandong 16Mn seamless steel pipe use and classification method: Shandong 16Mn seamless steel pipe use: special steel used for bridges is "16Mnq," special steel for automobile girders is "16MnL," and steel for pressure vessels is "16MnR." This steel type improves the mechanical properties of steel by adjusting the amount of carbon (C). According to the carbon content, these steels can be further divided into: low-carbon steels (carbon content is generally less than 0.25%, such as 10, 20 steel),...

The concept of spring steel: Spring steel is steel that is specially used to make springs and elastic elements due to the elasticity in the quenched and tempered state. The elasticity of steel depends on its elastic deformation ability. Jinguang is within the specified range. The ability of elastic deformation allows it to withstand a certain load, and no permanent deformation occurs after the load is removed. The characteristics of spring steel: The spring works mainly under dynamic load, that...
