Introduction to 1018 Steel and Its Characteristics
1018 steel, also known as mild steel, is a low-carbon steel widely used for machining and fabrication. Its versatility, ease of machining, and affordable cost make it a popular choice in industries such as automotive, manufacturing, and construction. 1018 steel contains approximately 0.18% carbon content, which places it in the category of low-carbon steels.
What is Mild Steel?
Mild steel refers to low-carbon steel with a carbon content ranging from 0.05% to 0.25%. Due to its low carbon content, it is malleable, ductile, and easy to form. Mild steel is often used in applications where strength is not a primary concern but where good weldability and machinability are essential.
