Product Description

Introducing our Low Carbon Steel Coil ASTM 569: a premium pickled and oiled carbon steel coil, designed to offer unparalleled durability and strength for your industrial needs.

 
Carbon steel, a versatile iron-carbon alloy, boasts a carbon content ranging from 0.0218% to 2.11%, earning it the name 'carbon steel.' It typically includes trace amounts of silicon, manganese, sulfur, and phosphorus. Notably, as the carbon content increases, so too does the steel's hardness and strength, although its plasticity decreases.

Classification

(1) Categorized by purpose, carbon steel is subdivided into three main classes: carbon structural steel, carbon tool steel, and free-cutting structural steel. Carbon structural steel further branches into engineering construction steel and machine manufacturing structural steel.
(2) Based on smelting methods, carbon steel is classified into open hearth steel and converter steel, each with distinct manufacturing processes.
(3) In terms of deoxidation, carbon steel is categorized into boiling steel (F), killed steel (Z), semi-killed steel (b), and special killed steel (TZ), each offering unique properties.
(4) Based on carbon content, carbon steel is segmented into low carbon steel (WC ≤ 0.25%), medium carbon steel (WC 0.25%-0.6%), and high carbon steel (WC > 0.6%), each providing specific performance characteristics.
(5) Regarding steel quality, carbon steel ranges from ordinary carbon steel (with higher phosphorus and sulfur content) to high-quality carbon steel (lower phosphorus and sulfur content), advanced high-quality steel, and extra high-quality steel with superior purity.

Common steel grades and their applications:

08F: Featuring a low carbon mass fraction, it offers excellent plasticity and low strength, ideal for stamping parts like automotive and instrument housings.
20: Renowned for good plasticity and weldability, this grade suits low-strength parts and carburized components, such as hoods, welding containers, small shafts, nuts, washers, and carburized gears.
45, 40Mn: Exhibiting commendable mechanical properties post-quenching and tempering, they serve demanding mechanical parts like gears, connecting rods, and machine tool spindles.
60, 65Mn steel is known for exceptional strength, making it ideal for springs, locomotive wheel flanges, and low-speed wheels manufacturing.
T7, T8: Crafted for components facing impact and demanding toughness, these grades are perfect for sledgehammers, punches, chisels, woodworking tools, and scissors.
T9, T10, T11: Engineered for tools requiring high hardness and wear resistance with minimal impact exposure. Ideal for taps, small drills, dies, and hand saw blades.
T12, T13: Designed for impact-resistant tools, including files, scrapers, razors, and precision measuring tools.

Hot rolling contrasts with cold rolling, as it occurs above the crystallization temperature, whereas cold rolling happens below.
Advantage:
(1) Hot rolling significantly curtails energy consumption and costs. During this process, the metal exhibits elevated plasticity and reduced deformation resistance, enhancing efficiency.
(2) Hot rolling significantly enhances the processing performance of metals and alloys. This process effectively breaks the coarse grains found in the casting state, heals cracks, and minimizes casting defects. As a result, the as-cast structure transforms into a deformed structure, elevating the processing performance of the alloy to a higher standard.
(3) Hot rolling is characterized by the use of large ingots and substantial rolling reductions. This not only boosts production efficiency but also lays the groundwork for increasing rolling speed and achieving a seamless, automated, and continuous rolling process.
