Description
Low alloy structural steel refers to alloy structural steel with a total alloy composition of less than 5%. The carbon content of this steel is similar to that of low-carbon steel, and it is mainly strengthened by a small amount of alloying elements to improve toughness and weldability. Its strength is much higher than that of carbon steel with the same carbon zinc. Widely used in pressure vessels, chemical equipment, boilers, Bridges, vehicles, ships and large steel structures. Alloy elements manganese, silicon, molybdenum inch to cause solid solution strengthening. Vanadium and niobium can refine grain size and improve toughness. Molybdenum can play a role in improving hardenability, promoting the acquisition of bainite structure, but also improve the thermal strength.
Application
1. Machinery manufacturing: The high strength and corrosion resistance of low alloy plate make it widely used in machinery manufacturing, automobiles, ships and other fields.
2. Construction field: Low alloy plate has good plasticity and corrosion resistance, and can meet the requirements of various shapes, sizes and building structures in the construction field, such as Bridges and building structures.
3. Energy field: The lightweight and high strength characteristics of low alloy plates make them widely used in the energy field, such as wind turbines, solar panels and so on.
4. Chemical industry: The corrosion resistance of low alloy plate can meet the requirements of various harsh environments in the chemical industry, such as petrochemical, fertilizer and other fields.
