Product Details

PRODUCT INFORMATION

1008 is a high-quality carbon steel, the front 10 represents the Mn content is less than 1%, and the back 08 represents the carbon (C) content: about 0.08%

1018 steel is high manganese and low carbon permeable steel, American standard SAE1018 low carbon steel. 10 represents carbon manganese steel, 18 represents carbon content, belongs to high-quality carbon steel. The manganese content of 1018 is relatively high, and the chemical composition of 16Mn or 15Mn,20Mn is similar to that of domestic. As a mild steel, similar properties to 1008.
