Comprehensive Classification
(1) Purpose-based Classification: Carbon steel is categorized into three main types: carbon structural steel, carbon tool steel, and free-cutting structural steel. Furthermore, carbon structural steel is sub-divided into engineering construction steel and machine manufacturing structural steel.
(2) Smelting Method Classification: Based on smelting techniques, carbon steel is classified as open hearth steel and converter steel.
(3) Deoxidation Method Classification: Carbon steel is categorized into boiling steel (F), killed steel (Z), semi-killed steel (b), and special killed steel (TZ), depending on the deoxidation process.
(4) Carbon Content Classification: Carbon steel is segmented into low carbon steel (WC ≤ 0.25%), medium carbon steel (WC 0.25%-0.6%), and high carbon steel (WC > 0.6%), reflecting its carbon content.
(5) Quality-based Classification: Carbon steel is divided into ordinary carbon steel (higher phosphorus and sulfur), high-quality carbon steel (lower phosphorus and sulfur), advanced high-quality steel, and extra high-quality steel.
Typical Steel Grades and Their Applications:
08F: Exhibiting low carbon mass fraction and excellent plasticity, this grade is ideal for stamping components like automobile and instrument housings.
20: Known for its exceptional plasticity and weldability, it is perfect for low-strength parts and carburized components, such as hoods, welding containers, small shafts, nuts, washers, and carburized gears.
45, 40Mn: With superior mechanical properties post-quenching and tempering, these grades are utilized in high-force mechanical parts like gears, connecting rods, and machine tool spindles.
60, 65Mn steel provides remarkable strength; utilized in manufacturing diverse springs, locomotive wheel flanges, and low-speed wheels.
T7, T8: Engineered for parts enduring notable impact while demanding resilience. Applicable for sledgehammers, punches, chisels, woodworking tools, and scissors.
T9, T10, T11: Designed for tools necessitating exceptional hardness and wear resistance with minimal impact, such as taps, small drills, dies, and hand saw blades.
T12, T13: Crafted for impact-resistant tools like files, scrapers, razors, and measuring tools.
The Science of Hot Rolling Hot rolling stands in contrast to cold rolling, where cold rolling occurs below crystallization temperature, while our hot rolling process operates above crystallization temperature for superior results.
Advantages of Hot Rolling:
(1) Hot rolling dramatically cuts energy consumption and costs. The metal's high plasticity and reduced deformation resistance during this process significantly ease metal deformation.
(2) Unleash the potential of metals and alloys with hot rolling, which significantly enhances their processing performance. By breaking down coarse grains from the casting state, healing cracks, and reducing or eliminating casting defects, hot rolling transforms the as-cast structure into a superior deformed structure, thereby maximizing the alloy's performance.
(3) Hot rolling employs large ingots and substantial rolling reductions to not only boost production efficiency but also pave the way for enhanced rolling speed. This innovation is key to achieving continuous and automated rolling processes, setting new standards in industrial excellence.
