Carbon steel is an iron-carbon alloy with a carbon content of 0.0218% to 2.11%. Also called carbon steel. Generally also contains a small amount of silicon, manganese, sulfur, phosphorus. Generally, the higher the carbon content in carbon steel, the greater the hardness and the higher the strength, but the lower the plasticity.
Classification
(1) According to the purpose, carbon steel can be divided into three categories: carbon structural steel, carbon tool steel and free-cutting structural steel, and carbon structural steel is further divided into engineering construction steel and machine manufacturing structural steel;
(2) According to the smelting method, it can be divided into open hearth steel and converter steel;
(3) According to the deoxidation method, it can be divided into boiling steel (F), killed steel (Z), semi-killed steel (b) and special killed steel (TZ);
(4) According to the carbon content, carbon steel can be divided into low carbon steel (WC ≤ 0.25%), medium carbon steel (WC0.25%-0.6%) and high carbon steel (WC>0.6%);
(5) According to the quality of steel, carbon steel can be divided into ordinary carbon steel (higher phosphorus and sulfur content), high-quality carbon steel (lower phosphorus and sulfur content) and advanced high-quality steel (lower phosphorus and sulfur content) ) and extra high-quality steel.
Common steel grades and uses:
08F, low mass fraction of carbon, good plasticity, low strength, used for stamping parts such as automobile and instrument housing;
20. Good plasticity and weldability, used for parts with low strength requirements and carburized parts, such as hoods, welding containers, small shafts, nuts, washers and carburized gears, etc.;
45, 40Mn, after quenching and tempering, the comprehensive mechanical properties are good, and it is used for mechanical parts with large force, such as gears, connecting rods, machine tool spindles, etc.;
60, 65Mn steel has high strength; it is used to manufacture various springs, locomotive wheel flanges, and low-speed wheels.
T7, T8: Make parts that withstand a certain impact and require toughness. Such as sledgehammers, punches, chisels, woodworking tools, scissors.
T9, T10, T11: Manufacturing tools that require high hardness and high wear resistance with low impact. Such as taps, small drills, dies, hand saw blades.
T12, T13: Make tools that are immune to impact. Such as files, scrapers, razors, measuring tools.
Cold rolling is a steel sheet in which the steel sheet is further thinned to a target thickness below the recrystallization temperature under room temperature conditions. Compared with hot rolled steel, the thickness of cold rolled steel is more accurate, and the surface is smooth and beautiful.
Hot rolling is to use continuous casting slabs or blooming slabs as raw materials, which are heated in a walking furnace, descaled by high-pressure water, and then enter the rough rolling mill. Rolling, after the final rolling, it goes through laminar cooling (computer-controlled cooling rate) and coiling by a coiler to become a straight coil. The head and tail of the straight hair curler are often tongue-shaped and fish-tail-shaped, with poor thickness and width accuracy, and the edges often have defects such as wave shape, folded edge, and tower shape. The coil weight is heavier, and the inner diameter of the steel coil is 760mm.

Application |
Stainless steel cold rolled coil is widely used in building material, medical tools, kitchen wares etc. 201 stainless steel is suitable for interior decoration, elevator decoration, hotel decoration, kitchen equipment, ceiling, cabinet, kitchen sink, advertising nameplate etc. 304 stainless steel is commonly used in the construction of external banisters and handrails, and it has good processing performance and weldability. 316L stainless steel is suitable for medical and surgical applications, which demand high levels of reliable performance. |
Hot rolled coil products like hot rolled steel bars are used in the welding and construction trades to make railroad tracks and I-beams. Hot rolled coil is used in situations where precise shapes and tolerances are not required. |
