12CrNi2 alloy structural steel is a commonly used metal material, which is widely used in various engineering fields because of its good mechanical properties and processing properties.
In this article, Shanghai Bohu will introduce the characteristics, application and production process of 12CrNi2 alloy structural steel in detail.
1. Characteristics of 12CrNi2 alloy structural steel 12CrNi2 alloy structural steel belongs to medium carbon steel, and its carbon content is about 012%。It contains alloying elements such as chromium and nickel, the addition of which significantly improves the mechanical properties and corrosion resistance of the steel. Compared with ordinary carbon steel, 12CrNi2 alloy structural steel has higher strength, toughness, and corrosion resistance, and can be used in harsher environments. In addition, 12CrNi2 alloy structural steel has excellent processing properties and is easy to cut, weld, and machine. Second, the application of 12CrNi2 alloy structural steel Because 12CrNi2 alloy structural steel has excellent mechanical properties and processing properties, it is widely used in various engineering fields. In ***, 12CrNi2 alloy structural steel is often used in the manufacture of key components such as automobile chassis, engine components and transmission systems. In the petrochemical industry, 12CrNi2 alloy structural steel is used in the manufacture of equipment such as oil tanks, pipelines and valves, which can withstand high temperatures, high pressures and corrosive media. In addition, 12CrNi2 alloy structural steel is also used in the manufacture of structural parts in the fields of construction, shipbuilding, aerospace and other fields. 3. The production process of 12CrNi2 alloy structural steelThe production process of 12CrNi2 alloy structural steel mainly includes smelting, continuous casting and rolling. In the smelting process, iron ore and scrap steel are melted into molten steel by electric furnace or converter, and then alloying elements such as chromium and nickel are added for alloying. The continuous casting process is to inject qualified molten steel into the continuous casting mold, and obtain a certain specification of billet through continuous pouring. The rolling process is to roll the billet into the required specifications and shapes, and after heat treatment and surface treatment, the final product is obtained. Fourth, the market prospect of 12CrNi2 alloy structural steelWith the continuous development of industrial technology and the thirst for high-performance materials, the application prospect of 12CrNi2 alloy structural steel is becoming more and more broad. In the future, with the improvement of environmental awareness and the popularization of new energy vehicles, the demand for 12CrNi2 alloy structural steel in the automotive industry will continue to grow. At the same time, with the continuous development of the petrochemical industry, the demand for corrosion-resistant, high-pressure and high-temperature resistant materials will further increase, providing a broader market space for the application of 12CrNi2 alloy structural steel.
