Hot Rolled Carbon Steel Coil — Product Description
Product Overview
Hot rolled carbon steel coils are general-purpose steel coils produced by hot rolling at temperatures above the recrystallization point. They are supplied in coil form with a mill scale surface, and are widely used in construction, manufacturing, cold forming, and general engineering applications. Available in grades Q235B, Q195, Q345B, SPHC, SS400, and A36, they meet the requirements of various international standards including GB/T 912, JIS G3101, ASTM A36, and EN 10025.
