The main chemical composition of 65Mn steel plate

The main chemical components of 65Mn steel plate include:

Carbon (C): The content is about 0.62% -0.70%. The higher carbon content endows steel with higher strength and hardness.

Manganese (Mn): The content is about 0.90-1.20%. Manganese can enhance the hardenability and strength of steel, while also improving its toughness.

Silicon (Si): The content generally does not exceed 0.37%. Silicon can improve the strength and hardness of steel, but excessive silicon can reduce the toughness of steel.

Sulfur (S) and phosphorus (P): The content is relatively low, usually not exceeding 0.035% and 0.030%, respectively. Low sulfur and phosphorus content can improve the quality and performance of steel.
