Classification of carbon steel square tubes

Classification of Carbon steel pipe fittings

Ordinary steel is carbon steel, also known as iron carbon alloy. According to the carbon content, Carbon steel pipe fittings can be divided into low-carbon steel square pipes (referred to as wrought iron), medium carbon steel square pipes, and cast iron. Generally speaking, if the carbon content is less than 0.2%, it is called a low-carbon square steel pipe, commonly known as wrought iron or pure iron. 0.2 ≤ 1.7% is called steel, and if the content exceeds 1.7%, it is called pig iron.
