Description:
It is a high-quality carbon structural steel with excellent comprehensive
toughness and strength .(Corresponding to Chinese brand: No. 45 steel, also known as: oil steel )
Chemical composition content:
High-quality carbon structural steel is carbon steel with a carbon content of less than 0.8%. This kind of steel contains less sulfur, phosphorus and non-metallic inclusions than carbon structural steel, and has excellent mechanical properties. The sulfur and phosphorus content of high-quality carbon structural steel is less than 0.035% and is mainly used to manufacture more important mechanical parts. The steel has a uniform metallographic structure and no structural defects.
