Carbon steel plate is a foundational material in structural engineering, heavy machinery, pressure vessel manufacturing, and marine construction. Defined primarily by its iron and carbon content—with minimal alloying elements—carbon steel plates are classified based on carbon content, production method, and specialized application requirements.
Classification by Carbon Content
The mechanical properties of carbon steel plates, particularly tensile strength, hardness, and weldability, are directly governed by their carbon concentration.
ASTM A36 hot rolled carbon steel plate is a general-purpose low-carbon structural steel produced to ASTM A36/A36M and supplied in the hot-rolled condition, with a minimum yield strength of 250 MPa and tensile strength of 400–550 MPa. Its low carbon content (0.25% max.) delivers excellent weldability without preheating, plus easy cutting, punching, drilling and bending. Widely used for building and industrial structures, bridges, machinery frames, tanks and silos. Cut-to-size service and mill test report available for every lot.
S235JR Carbon Steel Plate is a non-alloy structural steel plate manufactured to EN 10025-2, with a minimum yield strength of 235 MPa and tensile strength of 360–510 MPa. It offers excellent weldability, formability and toughness, and is equivalent to Q235B, SS400, ST37-2 and ASTM A283 Gr.C. We supply fully customized sizes — thickness 1.5–200 mm, width 1000–3000 mm, length up to 12000 mm — together with value-added processing such as laser/plasma/flame cutting, drilling, bending, shot blasting, galvanizing and painting. Mill test certificates (MTC) and third-party inspection reports (SGS/BV) are available on request. Typical uses include building structures, bridges, machinery parts, storage racks and general welded structures.
Engineered for extreme wear and heavy impact, our high manganese steel plates (Mn13 / Hadfield) feature outstanding self-work-hardening capabilities. Under mechanical shock, the surface hardness escalates from 200 HB up to 600 HB, creating an ultra-durable wear barrier while maintaining a tough core to prevent fracture.
