Classification
(1) Carbon steel, based on its intended application, is categorized into three principal types: carbon structural steel, carbon tool steel, and free-cutting structural steel. Further branching into engineering construction steel and machine manufacturing structural steel, carbon structural steel meets diverse engineering and manufacturing needs.
(2) Classified by smelting method, carbon steel divides into open hearth steel and converter steel, each offering distinct advantages for specific industrial applications.
(3) Deoxidation methods classify carbon steel into boiling steel (F), killed steel (Z), semi-killed steel (b), and special killed steel (TZ), each with unique attributes catering to precise manufacturing requirements.
(4) According to the carbon content, carbon steel is segmented into low carbon steel (WC ≤ 0.25%), medium carbon steel (WC0.25%-0.6%), and high carbon steel (WC>0.6%), each designed to fulfill specific strength and flexibility demands.
(5) The quality of steel divides carbon steel into ordinary carbon steel (with higher phosphorus and sulfur content), high-quality carbon steel (having lower phosphorus and sulfur content), advanced high-quality steel (lower phosphorus and sulfur content), and extra high-quality steel, fitting various quality standards.
Common steel grades and uses:
08F, featuring a low carbon mass fraction, is known for exceptional plasticity and moderate strength, ideal for crafting stamping parts like automobile and instrument housings.
20. Renowned for its superior plasticity and weldability, this grade is perfect for parts requiring low strength and carburized parts, including hoods, welding containers, small shafts, nuts, washers, and carburized gears.
With exemplary mechanical properties post-quenching and tempering, grades 45 and 40Mn serve critical roles in constructing high-stress mechanical parts like gears, connecting rods, and machine tool spindles.
60, 65Mn steel is celebrated for its high strength,making it perfect for manufacturing robust springs, locomotive wheel flanges, and low-speed wheels.
T7, T8: Designed for components requiring endurance against impact and a balance of toughness,ideal for crafting tools such as sledgehammers, punches, chisels, woodworking tools, and scissors.
T9, T10, T11: Perfect for producing tools demanding high hardness and wear resistance, but with minimal impact stress. Suitable for taps, small drills, dies, and hand saw blades.
T12, T13: Optimized for creating tools resistant to impact, including files, scrapers, razors, and precision measuring tools.
Hot rolling contrasts with cold rolling; while cold rolling occurs below the crystallization temperature, hot rolling takes place above it, offering unique material benefits.
Advantage:
(1) Hot rolling brings significant energy conservation and cost efficiency. The metal's high plasticity and low deformation resistance during hot rolling dramatically reduce deformation effort, making it a key process in various industries.
(2) Experience the transformative power of hot rolling that elevates the processing prowess of metals and alloys. As the coarse grains in the casting state are meticulously shattered, witness the significant healing of cracks, the notable reduction or elimination of casting defects, and the metamorphosis of the as-cast structure into a finely deformed one, enhancing the alloy's processing performance.
(3) Hot rolling harnesses the might of large ingots and extensive rolling reductions, not only revolutionizing production efficiency but also paving the way for enhanced rolling speed. This strategic approach enables the seamless realization of continuous and automated rolling processes.
