Comprehensive Classification Overview
(1) Carbon steel, based on its purpose, is divided into three principal types: carbon structural steel, carbon tool steel, and free-cutting structural steel. Delve into carbon structural steel, further categorized into engineering construction steel and machine manufacturing structural steel, each meticulously designed to satisfy unique industry specifications.
(2) Regarding the smelting process, carbon steel is classified into open hearth steel and converter steel, each possessing distinctive characteristics meticulously tailored to varied industrial applications.
(3) According to deoxidation methods, carbon steel is segmented into boiling steel (F), killed steel (Z), semi-killed steel (b), and special killed steel (TZ), each offering specialized benefits for targeted applications.
(4) Focusing 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%), each providing various degrees of strength and flexibility.
(5) By steel quality, carbon steel is categorized into ordinary carbon steel (with higher phosphorus and sulfur content), high-quality carbon steel (with reduced phosphorus and sulfur content), advanced high-quality steel, and extra high-quality steel, each engineered to meet specific requirements.
Diverse Steel Grades and Their Specialized Applications:
08F: Featuring a low carbon mass fraction, this steel offers superior plasticity and low strength, ideal for stamping components like automotive and instrument casings.
20: Renowned for its excellent plasticity and weldability, making it perfect for parts requiring low strength and carburized elements such as hoods, containers, small shafts, nuts, washers, and carburized gears.
45, 40Mn: Offering outstanding mechanical properties after quenching and tempering, these steels are perfect for high-stress mechanical components such as gears, connecting rods, and machine tool spindles.
60, 65Mn steel is distinguished by its remarkable strength; ideal for producing various springs, locomotive wheel flanges, and low-speed wheels.
T7, T8: Perfect for parts that withstand significant impacts and require exceptional toughness. Suitable for tools such as sledgehammers, punches, chisels, woodworking tools, and scissors.
T9, T10, T11: Meticulously designed for tools demanding extreme hardness and wear resistance with minimal impact. Ideal for taps, small drills, dies, and hand saw blades.
T12, T13: Crafted for tools resilient to impact, such as files, scrapers, razors, and precise measuring instruments.
Understanding Hot Rolling Hot rolling, in contrast to cold rolling, involves processing the metal above its recrystallization temperature, significantly improving its workability and structural integrity.
Unrivaled Advantage:
(1) Experience revolutionary cost efficiency with our hot rolling process, designed to dramatically reduce energy consumption and expenses. By enhancing plasticity and minimizing deformation resistance, our technique allows for substantial deformation, offering an exceptionally economical manufacturing solution.
(2) Discover the brilliance of hot rolling, where the transformation of metals and alloys reaches new heights. This process artfully refines coarse grains from the casting stage, expertly mends existing cracks, and skillfully minimizes or eliminates casting defects. Transitioning from an as-cast structure to a superior deformed structure elevates the processing performance of alloys, enhancing their strength and adaptability for a myriad of applications.
(3) Hot rolling is synonymous with utilizing large ingots and substantial rolling reductions. This strategic choice not only maximizes production efficiency but also sets the stage for elevated rolling speeds. Additionally, it establishes the conditions necessary for continuous and fully automated processes, revolutionizing the industry with its flawless and seamless operations.
