High-Strength S650MC S700MC CG700MC Carbon Steel Plate for Automotive Structural Applications with 6-25 mm Thickness

S650MC, S700MC, and CG700MC steel plates are high-strength, low-alloy hot-rolled steel sheets designed for automotive structural components and industrial machinery. Manufactured to international standards including GB, ASTM, EN, DIN, JIS, and AISI, these plates offer exceptional mechanical properties, excellent weldability, and consistent quality.

Typical thickness ranges from 3mm to 300mm, with widths of 1250mm to 2500mm and custom lengths according to project requirements. Produced in Shandong, China, by Kai Steel, these plates can be processed for bending, welding, decoiling, cutting, and punching, making them ideal for diverse engineering applications.

Modern automotive and industrial equipment require materials that combine high strength, lightweight, and excellent toughness. Traditional steel grades may not meet the mechanical performance needed for safety, durability, and cost efficiency in high-demand environments.

S650MC, S700MC, and CG700MC steel plates provide:

• Yield strength of 600-700 MPa (S650MC) and 700 MPa (S700MC)
• Tensile strength of 750-950 MPa
• Minimum elongation at fracture ≥ 10%
• High impact energy ≥ 27J
• Excellent weldability and machinability

These properties allow manufacturers to build stronger, lighter, and more durable structures for automotive, construction, energy, and industrial machinery applications.

• Automotive Industry - Car structural components, chassis, body panels, and impact-resistant parts
• Power Industry - Fan blades, burner pipelines, feeders, conveyor systems, ash pipes, and air handling systems
• Iron & Steel Industry - Hopper lining, crusher parts, slag troughs, vibrating screens, and base frames
• Cement Industry - Mill lining plates, impact plates, crusher parts, pump shells, and piping
• Paper Industry - Cyclone lining, screw conveyors, feeding troughs, and transition elbows
• Mining & Coal Processing - Truck cargo tank linings, hoppers, crushers, conveying troughs, elbows, and pump bodies
• Petrochemical & Boiler Applications - Reactors, heat exchangers, spherical tanks, gas tanks, wave gas tanks, high-pressure piping, and boiler shells

• Determine Load Requirements - Select S650MC or S700MC based on required yield strength and tensile strength
• Consider Application Environment - For high-temperature or corrosive conditions, check surface coating options
• Check Dimensions - Ensure thickness, width, and length match design specifications
• Processing Needs - Confirm bending, cutting, or welding capabilities before final selection
• Supplier Reliability - Choose manufacturers like Kai Steel with QC inspections and experience handling large orders

S650MC has a yield strength of 600-650 MPa, while S700MC has 700 MPa, offering higher tensile and impact strength for more demanding applications.

Yes, hot-rolled S650MC/S700MC plates are designed for bending, welding, punching, and decoiling.
