Special Steel Bar/Wire Rod

What is Special Steel?

Special steel is created by incorporating various elements into iron, giving it unique properties such as heat resistance, hardness, and corrosion resistance.

This versatile material is used in manufacturing and maintenance parts across a wide range of applications. From automobiles and other transportation equipment vital to modern society to household appliances, smartphones, and precision instruments, special steel plays a critical role in supporting both industrial and daily life.
