Description

Steel, Carbon CAS NO 11121-90-7 is a fundamental ferrous alloy material composed primarily of iron and carbon, with the carbon content being the key determinant of its mechanical properties. Its importance lies in providing an optimal balance of strength, ductility, and cost-effectiveness for a vast range of structural and functional applications. This material is essential for manufacturers and fabricators across the construction, automotive, machinery, and general engineering sectors.

Application

• Structural Components: Beams, columns, and frames for buildings, bridges, and industrial facilities.
• Automotive Parts: Chassis components, body panels, and various under-hood parts requiring strength and formability.
• Machinery and Tooling: Shafts, gears, fasteners, dies, and machine frames where durability is critical.
• Piping and Pressure Vessels: Tubes, pipes, and containers for industrial fluid and gas transport.
• Consumer and Industrial Goods: Appliances, furniture, storage racks, and agricultural equipment.
• Forging and Casting: Used as a base material for forged parts and castings in various industries.

Quality Control

Our carbon steel is produced and supplied to meet stringent international material standards, including but not limited to ASTM, AISI/SAE, EN, and JIS specifications. Quality is assured through rigorous in-process and final testing for chemical composition, mechanical properties (tensile strength, yield strength, elongation), and dimensional accuracy. Mill test certificates (MTC) or Certificates of Analysis (COA) detailing the specific grade's properties are provided with every shipment.

Storage

Preserve in a dry, well-ventilated warehouse. Store away from corrosive chemicals and environments to prevent rust and surface contamination. Pallets, coils, or sheets should be kept off the ground and properly supported to avoid deformation. Long-term storage may require protective coatings or covers.
