Classification
(1) When classified by purpose, carbon steel can be categorized into three distinct groups: carbon structural steel, carbon tool steel, and free-cutting structural steel. Specifically, carbon structural steel is further divided into engineering construction steel and machine manufacturing structural steel, expanding its range of applications.
(2) By smelting method, carbon steel is sorted into two types: open hearth steel and converter steel, each offering unique benefits.
(3) Based on deoxidation method, classifications include boiling steel (F), killed steel (Z), semi-killed steel (b), and special killed steel (TZ), each tailored for specific processes.
(4) According to the 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 offering distinct characteristics for varied use.
(5) Quality-based classification of carbon steel identifies ordinary carbon steel (higher phosphorus and sulfur), high-quality carbon steel (lower phosphorus and sulfur), advanced high-quality steel (even lower phosphorus and sulfur), and extra high-quality steel, each ensuring superior performance for specific needs.
Common steel grades and their practical uses include:
08F: Featuring a low carbon mass fraction, it offers excellent plasticity and low strength, ideal for stamping parts such as automobile and instrument housings.
20: Known for its good plasticity and weldability, this grade is suited for parts with low strength requirements and carburized components, including hoods, welding containers, small shafts, nuts, washers, and carburized gears.
45, 40Mn: After undergoing quenching and tempering, these grades exhibit outstanding comprehensive mechanical properties, making them perfect for mechanical parts under significant force, such as gears, connecting rods, and machine tool spindles.
60, 65Mn steel features remarkable high strength,making it ideal for manufacturing various springs, locomotive wheel flanges, and low-speed wheels.
T7, T8: Used for creating parts that endure moderate impact and necessitate exceptional toughness,such as sledgehammers, punches, chisels, woodworking tools, and scissors.
T9, T10, T11: Crafted for tools demanding superior high hardness and wear resistance with minimal impact, suitable for taps, small drills, dies, and hand saw blades.
T12, T13: Ideal for producing impact-resistant tools, such as files, scrapers, razors, and measuring tools, ensuring precision and durability.
Hot rolling distinguishes itself from cold rolling by occurring above the crystallization temperature, enhancing the metal's properties.
Advantage:
(1) Hot rolling substantially cuts down on energy consumption and costs. This process benefits from the metal's high plasticity and reduced deformation resistance, significantly diminishing metal deformation.
(2) Hot rolling is a transformative process that enhances the metallurgical properties of metals and alloys. By breaking down coarse grains from the casting state, it effectively heals cracks, reduces or eliminates casting defects, and converts as-cast structures into more refined deformed structures, thereby significantly improving the processing performance of the alloy.
(3) The hot rolling process incorporates large ingots and substantial rolling reductions, which not only boost production efficiency but also lay the foundation for increased rolling speeds. This process enables the realization of a continuous, automated rolling process, setting the stage for operational excellence.
