Hot Rolled Thin Carbon Steel Sheet 4.25mm

CSN/Usiminas Quality and Traceability Certification. A Hot Rolled Thin Carbon Steel Sheet 4.25 mm (GSC gauge #8) is a versatile product, widely used in structural and industrial applications. Manufactured by hot rolling according to standards. ASTM A36 e SAE 1008 / 1010 / 1020This sheet metal combines good mechanical strength, excellent weldability, and optimal performance in forming processes.

Characteristics of Hot Rolled Thin Sheet 4.25 mm

As hot-rolled sheets They have a slightly rough surface and homogeneous structure, resulting from the heating and compression process of the steel at high temperatures. This characteristic ensures malleability and ease of machining, making them ideal for the manufacture of medium-sized metal parts, profiles, and structures.
