Technical Parameter of Carbon Steel Plate

Carbon steel, refers to iron-carbon alloys with carbon content below 2% and 11%. Carbon steel is divided into carbon structural steel, carbon tool steel and free-cutting structural steel. Carbon structural steel is divided into engineering construction steel and mechanical manufacturing structural steel; according to the smelting method, it can be divided into open hearth steel and converter steel; 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 (WC 0.25%-0.6%) and high carbon steel (WC> 0.6%).

Mainly include: pig iron, carbon structural steel, high-quality carbon structural steel, low-alloy structural steel, alloy structural steel, spring steel and bearing steel, tool steel, stainless steel and heat-resistant steel.

Widely used in construction, bridges, railways, vehicles, ships and various machinery manufacturing industries, and also widely used in modern petrochemical, marine development, etc.

Production Process And Storage

Product Advantages of Carbon Steel Plate

  1. Improve performance, higher hardness and better wear resistance can be obtained after heat treatment.
  2. The hardness in the annealed state is very moderate, and it also has good machinability.
  3. The raw materials are very common and the production cost is low.
  4. The smelting process is simple, easy to smelt, and the dosage is large.
  5. Wide performance range, good pressure processing and machining performance.

Application of Carbon Steel Plate

Low carbon steel plates are mainly used in construction, machinery manufacturing, container manufacturing, shipbuilding, bridge construction, some parts of tractors and welded components, etc. Medium carbon steel plates are widely used in the manufacture of various mechanical parts, such as axles, gears or building materials. High carbon Steel plates are mainly used to make smaller parts, iron wire, hoops, knives, high-strength wire and springs, etc.

FAQs of Carbon Steel Plate

  1. Carbon steel sheet can be divided into three kinds of carbon structural steel sheet, carbon tool steel sheet and free-cutting structural steel sheet according to its usage. Carbon structural steel sheet can be further divided into steel sheet for engineering and construction and structural steel for machinery manufacturing.
  2. According to the smelting method, it can be divided into open hearth steel plate and converter steel plate.
  3. According to the method of deoxidation, it can be divided into boiling steel (F), killing steel (Z), semi-killing steel (b) and special killing steel (TZ).
  4. Carbon steel sheets can be divided into low carbon steel sheets (WC≤0.25%), medium carbon steel sheets (WC0.25%-0.6%) and high carbon steel sheets (WC>0.6%) according to the carbon content.
  5. According to the quality of steel sheet, carbon steel sheet can be divided into ordinary carbon steel sheet (higher phosphorus and sulfur content), high quality carbon steel sheet (lower phosphorus and sulfur content) and high grade high quality steel sheet (lower phosphorus and sulfur content). As well as super premium steel sheets.

About 0.25%~0.80%. Solid solution strengthening; remove FeO, reduce the brittleness of steel sheet; sulfide synthesis MnS, can reduce the harmful effect of sulfur. Useful.


About 0.10%~0.40%, solid solution strengthening; useful to eliminate the adverse effect of FeO on the quality of steel plate.


FeS forms low-melting eutectic with Fe (melting point is 985℃), which makes the steel plate brittle and cracking during hot working at 1000~1250℃, i.e. “hot brittleness”. Harmful.


Strength and hardness are improved, but plasticity and toughness are reduced, “cold brittleness”. Harmful.

Carbon structural steel sheet

Grade: Example Q235-A-F, i.e. σs=235MPa. Brand notes. Q is yield strength A quality grade (there are four grades of ABCD), F is boiling steel.
Features: Low price, excellent process properties (such as weldability and cold formability).

High quality carbon structural steel sheet

Species. Example 45, 65Mn, 08F.
Brand description: directly indicates the parts per million of carbon content in the metal.
Grade. Example: T12 steel plate indicates carbon tool steel with Wc=1.2%.
Brand description: T plus parts per thousand of the carbon content of the metal.
Features. It is eutectic and super eutectic steel plate with high strength, high hardness and good wear resistance. It is suitable for manufacturing various low-speed cutting tools.

Common steel plate grades and uses.

T7, T8: Used in the manufacture of parts that can withstand certain impact and require toughness. Such as sledgehammer, punch, chisel, woodworking tools, scissors.
T9, T10, T11: Manufacturing tools that require high hardness and high abrasion resistance, with less impact. Such as taps, small drills, dies, hand saw blades.
T12, T13: Manufacture tools that are not resistant to impact. Such as files, scrapers, razors, measuring tools.

Cast steel pieces

Grade. For example, ZG200-400, which means
Cast steel sheet with σs=200MPa and σb=400MPa.
Performance. Casting properties are worse than cast iron, but mechanical properties are better than cast iron.
