Instruction of Carbon Steel plate
When no minimum content of any alloying element (e.g., aluminum, chromium, nickel, molybdenum, vanadium, etc.) or any other element added to obtain the desired alloying effect is specified, the steel is normally considered to be carbon steel. Manganese is not to exceed 1.65%, copper has a specified minimum content of not less than .40% or more than .60%, and silicon is not to exceed .60%. There are low, medium and high carbon steel plates. The higher the carbon content of the plate, the more durable it will be.

Carbon content per carbon steel plate
Low carbon steel plate.
The maximum carbon content of low carbon steel is 0.30%. The largest category of low carbon steel includes carbon steel plate, which is a flat rolled product. These are usually used for automotive body parts, tin plate and wire products.
Medium carbon steel plate.
The carbon content of medium carbon steel ranges from 0.30% to 0.60%. Steel plate is mainly used for gear, axle, shaft and forging. Medium carbon steel with carbon content of 0.40% to 0.60% is used as railway material.
High carbon steel plate.
High carbon steel contains 0.60% to 1.00% carbon. Carbon steel plate can be used for strong wiring, spring material and cutting.
Ultra high carbon steel
Ultra high carbon steel is an experimental alloy containing 1.25% to 2.0% carbon. Carbon steel sheet is common in cutting tools.
With the increase of carbon content, the hardness of steel plate also increases.

(5) Cold-rolled raw plates:
used for the production of various cold-rolled products, including CR, GI, color coated plates, etc.
Benefits of Carbon Steel Plates
The most common types of carbon steel are low carbon steel or hot rolled steel. As a corrosion and wear resistant steel, carbon steel plate is very suitable for outdoor applications requiring durability to pressure and environmental pressure. Other benefits of carbon steel include.
- Compared with other steel plates, it has multifunction. Steel plates are available in a variety of thicknesses and widths
- Carbon steel plate has great ductility
- As an alternative to aluminum or stainless steel, it is cost-effective
- Strong plasticity and easy to manufacture
- Galvanizing can be carried out to prevent corrosion

FAQ
Classification by application
(1) Carbon steel sheets can be classified into three kinds of carbon structural steel sheets, carbon tool steel sheets and free-cutting structural steel sheets according to their uses. Carbon structural steel sheet can be further divided into engineering and construction steel sheet and structural steel for machinery manufacturing.
Classification by smelting method
(2) According to the smelting method, it can be divided into open hearth steel plate and converter steel plate.
Classification by deoxidation method
(3) According to the deoxidation method, it can be divided into boiling steel (F), killing steel (Z), semi-killing steel (b) and special killing steel (TZ).
Classification by carbon content
(4) Carbon steel sheet can be divided into low carbon steel sheet (WC≤0.25%), medium carbon steel sheet (WC0.25%-0.6%) and high carbon steel sheet (WC>0.6%) according to the carbon content.
Classification according to the quality of steel plate
(5) According to the quality of steel plate, 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 quality steel sheet (lower phosphorus and sulfur content). As well as super high grade steel plate.
Manganese
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.
Silicon
About 0.10%~0.40%, solid solution strengthening; useful to eliminate the adverse effect of FeO on the quality of steel plate.
Sulfur
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.
Phosphorus
Strength and hardness are improved, but plasticity and toughness are reduced, “cold brittleness”. Harmful.
