Comprehensive Classification
(1) Based on purpose, carbon steel is masterfully categorized into three illustrious types: carbon structural steel, carbon tool steel, and free-cutting structural steel. Further, carbon structural steel branches out into engineering construction steel and machine manufacturing structural steel, each designed for its unique application.
(2) When sorted by smelting method, carbon steel is divided into the traditional open hearth steel and the innovative converter steel.
(3) According to deoxidation techniques, carbon steel is classified into boiling steel (F), killed steel (Z), semi-killed steel (b), and special killed steel (TZ), each offering distinct properties.
(4) Taking carbon content into account, carbon steel is classed into low carbon steel (WC ≤ 0.25%), medium carbon steel (WC 0.25%-0.6%), and high carbon steel (WC > 0.6%), each variant tailored for specific needs.
(5) Evaluating quality, carbon steel spans ordinary carbon steel (with higher phosphorus and sulfur content), high-quality carbon steel (with reduced phosphorus and sulfur), advanced high-quality steel, and the elite extra high-quality steel, each tier offering superior refinement.
Common Steel Grades and Their Expert Applications:
08F, renowned for its low carbon mass fraction, offers excellent plasticity and minimal strength, making it ideal for stamping parts like automobile and instrument housing.
20. Praised for its superb plasticity and weldability, it's perfect for parts with modest strength demands and carburized components like hoods, welding containers, small shafts, nuts, washers, and carburized gears.
45, 40Mn, known for their exceptional mechanical properties post-quenching and tempering, are perfect for high-force mechanical parts such as gears, connecting rods, and machine tool spindles.
60, 65Mn steel possesses tremendous strength; it is ideal for crafting springs, locomotive wheel flanges, and low-speed wheels, boasting unmatched durability.
T7, T8: Crafted for components enduring moderate impacts, demanding superior toughness. Perfect for tools like sledgehammers, punches, chisels, woodworking implements, and scissors.
T9, T10, T11: Tailored for tool creation requiring ultimate hardness and wear resistance paired with minimal impact. Ideal for taps, small drills, dies, and hand saw blades.
T12, T13: Engineer tools designed to withstand no impact, such as files, scrapers, razors, and precision measuring tools.
Hot Rolling: The Art of Transformation Hot rolling contrasts with cold rolling, where cold rolling occurs below the crystallization point, while hot rolling takes place above this temperature, facilitating unique structural enhancements.
Advantages Unlocked:
(1) Hot rolling significantly curtails energy expenditure and cost. At elevated temperatures, metal exhibits high plasticity and reduced deformation resistance, vastly optimizing metal transformation.
(2) Revel in the transformative power of hot rolling! This process significantly enhances the workability of metals and alloys by fragmenting coarse grains, skillfully healing cracks, and reducing or even eradicating casting imperfections. The as-cast structure elegantly transitions into a deformed structure, unlocking improved processing performance for your alloys.
(3) Experience the efficiency of hot rolling with large ingots and substantial rolling reductions. This not only elevates production efficiency but also paves the way for increased rolling speeds, enabling seamless continuity and automation in the rolling process.
