Prime Hot/Cold Rolled SPCC Gr. 70 DC01 Ck45 SAE1040 Wear Weathering Resistant Ship/Vessel/Boiler/Mild/Alloy/Anti-Slip Checkered/CS Carbon Steel Coil Plate/Sheet

Cold rolled steel sheet  is made of hot rolled plate coil as raw material and rolled under recrystallization temperature at normal temperature. Cold rolled steel plate is the steel plate produced through cold rolling process, referred to as cold plate.

Cold rolled steel coil : using hot rolled steel coil as raw material, after pickling to remove the oxide scale for cold tandem rolling, the finished product is rolled hard coil, because of the continuous cold deformation caused by cold hardening of the rolled hard coil strength, hardness, toughness and plastic index decreased, so the stamping performance will deteriorate, can only be used for simple deformation of the parts.
Hard coils can be used as raw materials for hot dip galvanizing plants, because hot dip galvanizing units are equipped with annealing lines.
Rolling hard coil weight is generally 6~13.5 tons, steel coil at room temperature, hot rolled pickling coil for continuous rolling.
The inner diameter is 610mm.

(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.
 

Packaging & Shipping:
Water proof paper is inner packing,galvanized steel or coated steel sheet is outer packing , side guard plate,then wrapped by seven steel belt.or according to customer's requirement
