Basic Properties Of Steel Plates

The basic properties of steel plates mainly include their physical and chemical properties, mechanical properties, and performance in different applications.

Physical and chemical properties
Steel plates usually have a high density, which allows them to provide good support and protection when under pressure. Different types of steel plates differ in composition. For example, the main components of carbon steel are iron and carbon, while alloy steel may contain other elements such as manganese, silicon, nickel, etc., which will affect the performance of the steel plate.

Mechanical properties
The mechanical properties of steel plates include their tensile strength, yield strength, elongation, and hardness. For example, the tensile strength of No. 50 steel is ≥630MPa, the yield strength is ≥375MPa, the elongation is ≥14%, the hardness is ≤241HBS when not heat treated, and the surface hardness can reach 45~52HRC after quenching. These properties make steel plates perform well when subjected to mechanical effects such as tension, compression, and bending.

Application areas
Steel plates are widely used in many fields, including construction, bridges, shipbuilding, and automobile manufacturing. For example, carbon steel is often used in building structures and bridge construction due to its good weldability and low cost, while alloy steel is often used in fields such as petrochemicals and marine engineering due to its high strength and corrosion resistance. In addition, stainless steel plates are widely used in food processing, medical equipment, and high-end buildings due to their excellent corrosion resistance and beautiful surface.
