Comprehensive Classification
(1) Purpose-based Classification: Carbon steel segments into three distinct categories: carbon structural steel, carbon tool steel, and free-cutting structural steel. Furthermore, carbon structural steel divides into engineering construction steel and machine manufacturing structural steel for detailed applications.
(2) By Smelting Method: Carbon steel is categorized into open hearth steel and converter steel, each with distinct smelting advantages.
(3) Deoxidation Methodology: The classifications include boiling steel (F), killed steel (Z), semi-killed steel (b), and special killed steel (TZ), each offering unique benefits in metallurgical processes.
(4) By Carbon Content Classification by Carbon Content: 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%), each serving specific industrial purposes.
(5) Steel Quality Classification: Carbon steel is divided into ordinary carbon steel (with higher phosphorus and sulfur content), high-quality carbon steel (reduced phosphorus and sulfur content), advanced high-quality steel, and extra high-quality steel, each with improving purity levels.
Common Steel Grades and Their Applications:
08F: With a low carbon mass fraction and excellent plasticity, this grade is ideal for stamping components such as automobile bodies and instrument housings, where formability is key.
20: Known for its good plasticity and weldability, this grade is suited for parts with low strength requirements and carburized components, including hoods, welded containers, small shafts, nuts, washers, and carburized gears.
45, 40Mn: Post quenching and tempering, these grades offer superb mechanical properties, making them suitable for high-stress applications like gears, connecting rods, and machine tool spindles.
60, 65Mn: These steels are renowned for their remarkable high strength; they are essential in manufacturing a variety of springs, locomotive wheel flanges, and low-speed wheels.
T7, T8: These grades are crafted to make parts that endure significant impact while demanding robust toughness. This makes them perfect for sledgehammers, punches, chisels, woodworking tools, and scissors.
T9, T10, T11: Designed for tools requiring exceptional hardness and superior wear resistance with minimal impact. They are ideal for taps, small drills, dies, and hand saw blades.
T12, T13: Crafted for tools that resist impact, such as files, scrapers, razors, and precision measuring instruments.
The Dynamics of Hot Rolling Hot Rolling versus Cold Rolling: While cold rolling occurs below the crystallization temperature, hot rolling happens above it, offering distinct advantages.
Foremost Advantage:
(1) Through hot rolling, there is a substantial reduction in energy consumption and production costs. The process enhances metal plasticity and minimizes deformation resistance, enabling easier and more effective metal shaping and forming.
(2) Hot rolling is a transformative process that significantly elevates the quality and usability of metals and alloys. Through this process, the coarse grains inherent in the casting state are meticulously broken down, while cracks are seamlessly healed, leading to a marked reduction or complete elimination of casting defects. This technique ingeniously converts the as-cast structure into a refined deformed structure, thereby vastly enhancing the metal's processing performance and reliability.
(3) Hot rolling not only uses large ingots for substantial rolling reductions but also vastly boosts production efficiency. This method sets the stage for accelerated rolling speeds and seamlessly paves the way for continuous, automated rolling processes, leading to an advanced, streamlined manufacturing workflow.
