Carbon Steel Round Bar

Carbon Steel Round Bar, formerly known as ordinary carbon structural steel, refers to steel that does not contain intentionally added alloy elements and is mainly used for construction and engineering structures.

To put it simply: High-quality carbon structural steel is referred to as carbon-bonded steel. Specifically speaking, carbon-bonded round steel has a carbon content of less than 0.08%. Compared with ordinary carbon steel, its quality is better, it has strict chemical composition and requires guaranteed mechanical performance indicators, high-quality carbon structural steel with lower content of phosphorus, sulfur and other impurities.

The types of carbon steel can be divided into two groups according to the manganese content: normal manganese content (0.25%-0.80%) and higher manganese content (0.70%-1.20%). The latter has better mechanical properties and Processing performance. The types of carbon steel are divided into three categories according to the carbon content: low carbon steel, medium carbon steel and high carbon steel.

Carbon structural steel is an important structural material widely used in various fields. Its strengths lie in its proper structure, rich usage.
