Performance Characteristics
Mechanical Properties
Strength and Hardness: Carbon content directly affects performance. Low-carbon steel (≤0.25%) has good plasticity and high toughness, suitable for cold working; medium-carbon steel (0.25%-0.60%) has moderate strength, and its overall performance can be improved through heat treatment; high-carbon steel (>0.60%) has high hardness and strong wear resistance, but lower plasticity and toughness.
Processing Performance: Low-carbon steel is easy to weld and stamp, while high-carbon steel requires special treatment (such as quenching and tempering) to reduce brittleness.
Environmental Adaptability
Corrosion Resistance: Carbon steel is easily oxidized and requires enhanced protection through galvanizing, painting, or alloying (such as weathering steel), especially in humid environments.
Temperature Resistance: The upper limit of long-term operating temperature for ordinary carbon steel is approximately 350°C. For high-temperature environments, heat-resistant steel must be used.
Economic Efficiency
Low cost, approximately one-third the price of stainless steel, suitable for large-scale production, making it the "king of cost-effectiveness" in industrial materials.
Main Applications
Building Engineering
Structural Support: Low-carbon steel (e.g., Q235B) is used for factory frames and bridge main beams, balancing strength and cost; high-strength steel (e.g., HC340LA) is used for weight reduction in high-rise buildings.
Enclosure Systems: Galvanized carbon steel sheets (e.g., DX51D) are used for roofing and wall panels, improving rust resistance.
Machinery Manufacturing
Transmission Components: Medium-carbon steel (e.g., 45#) is heat-treated to manufacture gears and shafts, balancing strength and toughness.
Equipment Housings: Cold-rolled steel sheets (e.g., SPCC) are used for machine tool protective covers, with a surface coating to prevent oil stains.
Automotive Industry
Body Structure: Low-carbon steel sheets (such as DC04) are used for doors and hoods to achieve lightweighting and impact energy absorption; high-strength steel is used for chassis components to increase strength and reduce weight.
Shipbuilding and Energy
Ship Construction: Marine carbon steel (such as AH36) passes low-temperature impact testing to ensure safety during polar navigation.
Energy Pipelines: Pipeline steel (such as API5L Gr.B) is used for oil and gas transportation, with a yield strength ≥245 MPa.
Future Trends
With the development of green buildings, carbon steel sheets are increasingly used in energy-saving projects, such as negative carbon demonstration buildings that use high-performance envelope systems combined with photovoltaic technology to improve energy efficiency.

FAQ
Q1: What is the difference between mild steel and structural plate?
Mild steel is low carbon and easily formable; structural plates like Q345 or S355 have higher strength and are used in load-bearing applications.
Q2: Do you supply boiler-grade carbon steel plate?
Yes. We offer ASTM A516, Q245R, and related grades suitable for pressure vessels and tanks.
Q3: Can you cut the plate into parts or flanges?
Absolutely. We support precision plasma cutting to custom drawings.
Q4: What are your available thicknesses?
We stock from 2mm thin sheets to 300mm heavy plates.
Q5: Is carbon steel plate suitable for outdoor environments?
Yes, especially grades like A588 or painted surfaces for weather resistance.
