Carbon Steel Plate SAC 350 5/16"

A carbon steel plate SAC 350 5/16"(7.94 mm) is ahot rolled thick platehigh strength and durability, developed byUsiminasaccording to strict quality standards. This material belongs to the family ofweathering steels (Weathering steels), designed to resist atmospheric corrosion by forming a natural protective layer — thepatina— which eliminates the need for painting in many external applications.

Technical description of SAC 350 5/16" sheet

With nominal thickness of7.94 mm, theSAC 350 plateIt offers an excellent balance of mechanical strength, ductility, and corrosion resistance. The steel is produced using a hot-rolled process, ensuring a uniform finish, dimensional stability, and high structural reliability.

• Yield strength (Fy):≥ 350 MPa
• Tensile strength (Fu):470 – 630 MPa
• Minimum stretch:20%
• Modulus of elasticity:200 GPa
• Density:7.85 g/cm³
• Typical chemical composition (%): C ≤ 0.12 | Mn ≤ 1.50 | Si 0.25–0.75 | P ≤ 0.04 | S ≤ 0.03 | Cu 0.25–0.55 | Cr 0.40–0.65 | Ni ≤ 0.65

Features and advantages

• Natural corrosion resistance:the patina formed on the surface protects the steel against continuous oxidation, eliminating the need for painting in many applications.
• Superior durability:much longer service life than conventional carbon steels in outdoor environments.
• Excellent weldability and formability:allows cutting, bending, chamfering, trimming and calendering with precision and safety.
• Differentiated aesthetics:reddish-brownish color, widely used in modern architectural and decorative projects.
• Certification of origin:material provided with complete reports ofUsiminas, CSN, Gerdau e ArcelorMittal.
