ASTM A366, ASTM A569 Steel Product Information -:- For detailed product information, please contact sales. -: ### **Technical Data Sheet: ASTM A366 / A366M & ASTM A569 Steel** --- #### **1. Product Overview** **ASTM A366/A366M** covers steel sheet, carbon, cold-rolled, commercial quality, which is produced from continuously cast or ingot-cast steel. This specification is typically used for applications requiring good surface quality and uniformity in thickness. **ASTM A569** covers steel sheet, carbon, hot-rolled, commercial quality, which is produced from continuously cast or ingot-cast steel. This material is suitable for applications where surface finish is not of primary importance. Both specifications represent commercial quality steels with good formability and weldability, suitable for general purpose applications. --- #### **2.
