3/8" Carbon Steel Plate

CSN / Usiminas Quality and Traceability Certification. A 3/8" ASTM A36 carbon steel plate(9.53 mm) is ahot rolled thick plateWidely used in structural and mechanical applications requiring strength, durability, and excellent welding and forming performance. Produced according to the standardsASTM A36 e NBR 6650, is a versatile and economical material, ideal for infrastructure works, industrial manufacturing and heavy boilermaking.

Technical characteristics of 3/8" A36 Carbon Steel Plate

With nominal thickness of9.53 mm(or 10 mm), thethick plate A36presents an excellent balance between strength and formability. The process ofhot rollingIt gives the steel a uniform structure, excellent ductility, and a surface finish suitable for painting, galvanizing, or machining. The material is easily cut, bent, and welded, making it ideal for structural metal components.
