It delivers moderate strength paired with excellent toughness, meeting the demands of most general structural and mechanical applications:
Moderate Strength: Boasts a tensile strength of 400–552 MPa and a minimum yield strength of 221 MPa. This strength level is sufficient for non-high-load scenarios, such as ordinary structural supports, frame components, and hardware parts.
Excellent Toughness & Ductility: Exhibits a high elongation rate (approximately 20% in tensile tests), meaning it can withstand a certain degree of deformation (e.g., bending, stretching) without cracking or breaking. This makes it ideal for applications requiring shaping or resistance to occasional impact.
Stable Performance: The low-carbon composition (carbon content typically 0.25–0.29%) ensures consistent mechanical properties across batches, avoiding significant performance fluctuations that could affect end-product reliability.
II. Superior Processability
Its material characteristics make it easy to machine and fabricate using common equipment, reducing production complexity and costs:
Excellent Weldability: One of its standout advantages—all standard welding processes (e.g., arc welding, MIG welding, TIG welding) can be applied effortlessly. Welded joints have high strength and good integrity, requiring no specialized pre-welding or post-welding treatments (e.g., heat treatment) for most general uses.
Easy Formability: Can be easily bent, punched, drilled, sheared, or rolled into custom shapes using conventional metalworking tools (e.g., press brakes, drills, shears). Even cold forming (without heating) rarely causes material brittleness, simplifying manufacturing workflows.
Good Machinability: Performs well in cutting, grinding, and milling operations. It produces clean, smooth surfaces during machining, minimizing the need for secondary finishing (e.g., polishing) for non-precision parts.
III. Cost-Effectiveness (Aligned with "Factory Price" Advantage)
As a standardized low-carbon steel product, it offers exceptional value for money, especially when sourced at factory prices:
Low Raw Material & Production Costs: Mild steel (the base material) is abundant and low-cost globally. The manufacturing process for flat bars (e.g., hot rolling, cold drawing) is mature and energy-efficient, keeping overall production costs low.
Reduced Processing Costs: Its superior weldability and formability eliminate the need for expensive specialized equipment or complex processing steps (e.g., preheating for welding, heat treatment after forming), lowering downstream manufacturing expenses.
Factory Price Benefit: Sourcing directly from manufacturers avoids middlemen markups, making it one of the most economical flat steel options for bulk applications (e.g., construction projects, mass-produced hardware).
IV. Wide Application Versatility
Thanks to its balanced performance and cost, it is used across numerous industries and scenarios:
