Supplier highlights:This supplier mainly exports to the Democratic Republic of Congo, the UK, and Brazil. They offer full customization, design customization, and sample customization services, and have product certifications.
High Tensile & Yield Strength: The hot rolling process refines the steel’s grain structure, enhancing its mechanical properties. For common carbon steel grades (e.g., Q235, A36, S235JR), these thick plates typically have a yield strength of 235–355 MPa and tensile strength of 375–500 MPa, enabling them to withstand heavy static/dynamic loads (e.g., pressure from industrial equipment, structural weight in large buildings).
Thickness-Driven Stability: The 60mm and 200mm gauges provide exceptional rigidity and resistance to bending or deformation, making them ideal for load-bearing components like bridge girders, machine bases, or pressure vessel shells (where thin plates would fail under stress).
2. Process-Related Material Properties
Workability (Hot Formability): Hot rolling leaves the steel in a ductile state (due to high-temperature processing), allowing post-production shaping (e.g., bending, welding, cutting) without excessive brittleness. Even the 200mm thick plates can be machined into custom structural parts (e.g., thick flanges, heavy brackets) with standard industrial equipment.
Grain Structure Advantage: Compared to cold rolled steel (processed at room temperature), hot rolled carbon steel has a coarser but more uniform grain structure, which improves its impact toughness—critical for applications exposed to low temperatures or sudden loads (e.g., outdoor infrastructure in cold climates).
3. Cost-Effectiveness for Heavy-Duty Applications
Lower Production Costs: The hot rolling process is simpler and more energy-efficient than cold rolling (no need for multiple cold-working passes), especially for thick plates. This makes 60mm/200mm hot rolled plates more affordable than equivalent thick cold rolled or alloy steel alternatives.
Minimal Material Waste: Hot rolled plates are produced in standard or customizable widths/lengths (e.g., 1500mm–4000mm width, 6000mm–12000mm length), reducing the need for excessive cutting and minimizing waste in large-scale projects.
4. Versatile Adaptability to Grades & Applications
Grade Customization: These thick plates are available in various carbon steel grades to match specific needs:
Low-carbon grades (e.g., Q235, A36): High ductility, easy welding—used for general structural parts (building columns, warehouse beams).
Medium-carbon grades (e.g., 45#): Higher hardness and strength—suitable for machine components (heavy-duty shafts, gears) that require wear resistance.
Thickness-Specific Use Cases:
60mm: Balances strength and workability—ideal for pressure vessels, boiler parts, or medium-load structural frames.
200mm: Ultra-heavy gauge for extreme loads—used in large-scale engineering (bridge piers, offshore platform foundations, heavy machinery bases).
