Classification: An in-depth guide to understanding the diverse types and categories of our distinguished carbon steel products.
(1) According to the purpose, carbon steel is categorized into carbon structural steel, carbon tool steel, and free-cutting structural steel. Further, carbon structural steel is sub-divided into engineering construction steel and machine manufacturing structural steel, each serving specific industry needs with unmatched precision.
(2) Based on smelting techniques, carbon steel is classified as either open hearth steel or converter steel, each offering unique properties tailored to diverse applications.
(3) The deoxidation method leads to four distinct categories: boiling steel (F), killed steel (Z), semi-killed steel (b), and special killed steel (TZ). Each type is crafted to suit specific requirements, enhancing performance and quality.
(4) With regards to 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%). This categorization allows for the selection of steel with the ideal balance of strength and plasticity for any project.
(5) Steel quality further delineates carbon steel into ordinary carbon steel, high-quality carbon steel, advanced high-quality steel, and extra high-quality steel, each offering varying levels of phosphorus and sulfur content. These variations ensure the material meets the demanding standards of high-performance applications.
Common Steel Grades and Uses: Explore the versatility of our steel grades and their applications, each designed to meet specific industrial needs.
08F: Featuring a low mass fraction of carbon, 08F steel is renowned for its excellent plasticity and low strength. This makes it ideal for stamping parts such as automobile and instrument housings, offering reliability and quality.
20: Boasting good plasticity and weldability, this steel grade is suited for parts with low strength requirements. It is perfect for carburized components like hoods, welding containers, small shafts, nuts, washers, and carburized gears, ensuring durability and performance.
45, 40Mn: These grades, after quenching and tempering, exhibit outstanding mechanical properties. They are widely used in high-force mechanical parts such as gears, connecting rods, and machine tool spindles, providing robustness and longevity.
60, 65Mn steel is recognized for its high strength; ideal for manufacturing various springs, locomotive wheel flanges, and low-speed wheels, delivering reliability and durability in demanding applications.
T7, T8: Designed for components that require exceptional toughness. Perfect for tools like sledgehammers, punches, chisels, woodworking tools, and scissors, ensuring resilience and precision.
T9, T10, T11: These tool steels are crafted for maximum hardness and wear resistance in low-impact scenarios. They are essential for manufacturing taps, small drills, dies, and hand saw blades, where precision and durability are critical.
T12, T13: Tailored for tools that require immunity to impact, such as files, scrapers, razors, and measuring tools, ensuring performance and longevity under rigorous conditions.
Hot Rolling: A preferred technique that stands in contrast to cold rolling. While cold rolling occurs below the crystallization temperature, hot rolling takes place above this threshold, offering distinct benefits.
Advantage:
(1) Hot rolling dramatically minimizes energy consumption and costs. The process benefits from the metal's high plasticity and low deformation resistance, effectively reducing metal deformation and enhancing efficiency for large-scale operations.
(2) Experience the enhanced processing performance of metals and alloys through hot rolling. This transformative process breaks down coarse grains from the casting state, significantly heals cracks, reduces or eliminates casting defects, and morphs the as-cast structure into a refined deformed structure, elevating the alloy's processing capabilities.
(3) Hot rolling is characterized by the use of large ingots and substantial rolling reductions, which not only boost production efficiency but also pave the way for heightened rolling speeds and the seamless integration of continuous and automated rolling processes.
