Four Major Properties of Metallic Materials

The ability of a metal to resist deformation and fracture when it is subjected to external forces under certain temperature conditions is called the mechanical properties of the metal material.

Summary of Basic Knowledge of Metal Heat Treatment

Metal heat treatment is one of the important processes in mechanical manufacturing. Compared with other processing processes, heat treatment generally does not change the shape and overall chemical composition of the steel product, but changes the micro-structure inside the item or changes the chemical composition of the surface

How Carbon Steel is Classified Based on Carbon Content

Carbon steel is an iron-carbon alloy with a carbon content of 0.0218%-2.11%. It generally contains small amounts of silicon, manganese, sulfur, and phosphorus. The higher the carbon content in carbon steel, the greater the hardness and strength, but the lower the plasticity.
