Classification
(1) Carbon steel, a pivotal material in the industry, is categorized into three main types based on its purpose: carbon structural steel, carbon tool steel, and free-cutting structural steel. Delving deeper, carbon structural steel is further split into essential subcategories, namely engineering construction steel and machine manufacturing structural steel, which play crucial roles in infrastructure and machinery production.
(2) The steel production process can be classified by the smelting method, creating two distinct categories: open hearth steel, known for its traditional and controlled smelting process, and converter steel, which leverages modern technology for efficient steel production.
(3) Based on the deoxidation method, steel is further differentiated into boiling steel (F), killed steel (Z), semi-killed steel (b), and special killed steel (TZ), each offering unique properties that suit various applications and manufacturing needs.
(4) Considering the carbon content, carbon steel is segmented into low carbon steel (WC ≤ 0.25%) for superior ductility, medium carbon steel (WC 0.25%-0.6%) for a balance between strength and plasticity, and high carbon steel (WC > 0.6%) for exceptional hardness and strength.
(5) Analyzing the steel quality, carbon steel is classified into ordinary carbon steel, characterized by higher levels of phosphorus and sulfur; high-quality carbon steel, with reduced impurities; advanced high-quality steel, offering even better purity; and extra high-quality steel, providing the utmost in cleanliness and performance.
Common steel grades and uses:
08F, featuring a low carbon mass fraction, excels in plasticity but is low in strength, making it ideal for stamping components like automobile and instrument housings.
20, celebrated for its excellent plasticity and weldability, is perfect for components with minimal strength demands and carburized parts, such as hoods, welding containers, small shafts, nuts, washers, and carburized gears, delivering versatility in application.
45, 40Mn, known for their balanced mechanical properties post-quenching and tempering, are used in high-stress mechanical parts like gears, connecting rods, and machine tool spindles, ensuring durability and performance.
60, 65Mn steel stands out with remarkable strength; thus, it is frequently chosen for manufacturing a range of springs, locomotive wheel flanges, and low-speed wheels, ensuring reliability and longevity.
T7, T8: These grades are perfect for crafting components that must endure specific impacts while maintaining toughness, such as sledgehammers, punches, chisels, woodworking tools, and sturdy scissors, embodying resilience.
T9, T10, T11: These steels are tailored for making tools that demand extreme hardness and superior wear resistance while withstanding minimal impact, making them suitable for items like taps, small drills, dies, and hand saw blades, showcasing precision and endurance.
T12, T13: Ideal for crafting impact-resistant tools, such as files, scrapers, razors, and measuring tools, offering consistent performance.
Hot rolling is a process distinct from cold rolling, where rolling is performed above the crystallization temperature, enhancing the material's structural integrity and efficiency.
Advantage:
(1) Hot rolling significantly slashes energy usage and costs. The metal exhibits high plasticity and minimal deformation resistance, facilitating easier manipulation of the material's form.
(2) Hot rolling enhances metals and alloys' processing performance. The process breaks coarse grains from casting, heals cracks, and minimizes casting defects, transforming the as-cast structure into a more refined deformed one.
(3) Utilizing substantial ingots and large rolling reductions in hot rolling boosts production efficiency while paving the way for increased rolling speeds and enabling continuous, automated rolling processes.
