Overview

Carbon steel sheets are one of the most common types of steel. The specific type of carbon steel sheet is selected based on how it will be used.Carbon structural steel plate refers to carbon steel with less than 0.8% carbon. This kind of steel contains less sulfur, phosphorus and non-metallic inclusions than carbon structural steel, and has better mechanical properties. According to different manganese content, carbon structural steel is divided into two groups: normal manganese content (manganese 0.25%-0.8%) and higher manganese content (manganese 0.70%-1.20%). The latter has better mechanical properties. And processing performance.

Carbon steel is also magnetic as it has a certain amount of Iron that makes magnets stick to it. Stainless Steel and Aluminum both do not have enough (or at all) iron, cobalt or nickel mixed into the alloy to be magnetic.

Advantages

  1. After heat treatment, hardness and wear resistance can be improved.
  2. The hardness is appropriate when annealed, and the machinability is good.
  3. Its ingredients are common and therefore easy to find, so it is not expensive to produce.

Finishing and Treating

Steel sheets and plates are made by rolling a slab of steel through a series of rollers until the desired thickness and material properties are achieved. Each stage in the rolling and finishing process produces a salable sheet or plate with distinct finish and properties.

Application

There are many uses and a large amount. It is mainly used in railways, bridges, and various construction projects to manufacture various metal components that bear static loads, as well as unimportant mechanical parts and general welded parts that do not require heat treatment. Usually used for welding, riveting, and bolting hot-rolled steel plates, steel strips, steel channels and steel bars for engineering structures.

Application

At Qinghe Steel, we supply a wide range of carbon steel sheets for sale for a variety of applications. Our product range includes Hot Rolled Carbon Steel Sheet, Cold Rolled Carbon Steel Sheet, Hot Dipped Galvanized Carbon Steel Sheet that are in sync with different commercial grades and international standards.

FAQ

What is the material of carbon steel plate?

It is a kind of steel whose carbon content is less than 2.11% and no metal elements are intentionally added. It can also be called plain carbon steel or carbon steel. In addition to carbon, it also contains a small amount of silicon, manganese, sulfur, phosphorus and other elements. The higher the carbon content, the better the hardness and strength, but the plasticity will be worse. View more information about carbon steel.

What are the advantages and disadvantages of carbon steel plate?

Its advantages are:

  1. After heat treatment, the hardness and wear resistance can be improved.
  2. Proper hardness and good machinability during annealing.
  3. Its raw materials are very common, so it is easy to find, so the production cost is not high.

Its disadvantages are:

  1. Its thermal hardness is not good. When it is used as tool material, the hardness and wear resistance will become worse when the temperature exceeds 200 ℃.
  2. Its hardenability is not good. Its diameter is usually maintained at 15 to 18 mm when it is water quenched, while its diameter and thickness are usually 6 mm when it is not quenched. Therefore, it is prone to deformation or cracking.

What standards referred to carbon steel plate?

Carbon steel plate almost include all the common standards of steel plate/sheet.

  1. ASTM A36 plates – The most common standards of carbon steel plate
  2. ASTM A283 Grade A, B, C – Also most common material in carbon structural.
  3. ASTM A516 – For boiler, vessel steel plate.
  4. ASTM A537 – For heat treated carbon steel plate in fusion welded pressure vessels and structural steel plates.
  5. ASTM A573 – A kind of structural steel plate with carbon-manganese-silicon.
  6. ASTM A572 – ASTM A572 plate mechanical strength is higher than A36. Where with lower weight.
  7. ASTM A737 – For boiler, pressure vessels steel plate of low alloy steel.

and etc..

So carbon steel plates have a widely coverage for different types of steel plates in different industries.
