Categorization
(1) Based on their application, carbon steels are classified into three main types: carbon structural steel, carbon tool steel, and free-cutting structural steel. Carbon structural steel further subdivides into engineering construction steel and machine manufacturing structural steel, providing solutions for varied industrial demands.
(2) When categorized by smelting techniques, carbon steel is differentiated into open hearth steel and converter steel, each offering distinct characteristics and benefits.
(3) According to deoxidation methods, the variations include boiling steel (F), killed steel (Z), semi-killed steel (b), and special killed steel (TZ), each crafted for specific performance requirements.
(4) Based on carbon content, carbon steel is divided into low carbon steel (WC ≤ 0.25%), medium carbon steel (WC 0.25%-0.6%), and high carbon steel (WC > 0.6%), catering to a wide range of strengths and applications.
(5) By evaluating steel quality, carbon steels are classified into ordinary carbon steel (higher phosphorus and sulfur content), high-quality carbon steel (lower phosphorus and sulfur content), advanced high-quality steel, and extra high-quality steel, each designed for specific industry standards.
Popular Steel Grades and Their Applications:
08F steel is characterized by a low carbon mass fraction, offering excellent plasticity and reduced strength, ideal for stamping parts like automobile and instrument housings.
20 steel exhibits superb plasticity and weldability, perfect for low-strength requirements and parts needing carburization, such as hoods, welding containers, small shafts, nuts, washers, and carburized gears.
With exceptional mechanical properties post-quenching and tempering, 45 and 40Mn steels are suitable for high-stress mechanical components, including gears, connecting rods, and machine tool spindles.
60 and 65Mn steels are renowned for their robust strength; these steels are utilized in manufacturing a variety of springs, locomotive wheel flanges, and low-speed wheels.
T7 and T8 steels are chosen for crafting parts that endure impact while maintaining superior toughness. Ideal for producing sledgehammers, punches, chisels, woodworking tools, and scissors.
For tools necessitating extraordinary hardness and wear resistance with minimal impact, such as taps, small drills, dies, and hand saw blades, T9, T10, and T11 steels are the materials of choice.
T12 and T13 steels are tailored for tools impervious to impact, including files, scrapers, razors, and measuring tools.
Hot Rolling Process Contrasting with cold rolling, hot rolling is conducted above the metal's crystallization temperature, yielding distinct material properties.
Benefits:
(1) Hot rolling dramatically lowers energy consumption and cost. The metal's heightened plasticity and reduced deformation resistance during the process significantly ease deformation, optimizing efficiency and output.
(2) Hot rolling offers remarkable enhancements in the processing performance of metals and alloys. This transformative process breaks down the coarse grains present in the casting state, significantly healing cracks and reducing or even eliminating casting defects. The as-cast structure metamorphoses into a deformed structure, thereby greatly enhancing the alloy's processing capabilities.
(3) Hot rolling predominantly utilizes large ingots and substantial rolling reductions, which not only elevates production efficiency but also fosters an environment ripe for boosting rolling speed. This progression paves the way for the continuous automation of the entire rolling process, leading to unparalleled efficiency.
