Product Description
ASTM Q345 45# Carbon Steel Bar Metal Rod Black Seamless Round Rod
Round steel is categorized into three types: hot rolled, forged, and cold drawn. Hot-rolled round steel specifications range from 5.5-250mm. Small round steel bars (5.5-25mm) are typically supplied as straight bars and commonly used for steel reinforcement, bolts, and various mechanical components. Round steel larger than 25mm is primarily utilized in manufacturing mechanical parts and as billets for seamless steel pipes.
