Alloy steel plates

4140QT-PLATE

sheet2_

With the development of science, technology and industry, higher requirements are put forward for materials, such as higher strength, resistance to high temperature, high pressure, low temperature, corrosion, wear and other special physical and chemical properties. Ordinary carbon steel plate can no longer fully meet the requirements, so alloy steel plates appear.

Alloy Steel Plates are steel these are alloyed with a different elements in overall quantities among 1.0% and 50% by weight to enhance its mechanical properties. Alloy steels have to type which is low-alloy steels and high-alloy steels. The difference between the two is relatively arbitrary.

Alloy steel plates are defined as steel plates with a definite range or definite minimum quantity of additional elements, depending on the alloy.

Classification of alloy steel

According to the content of alloy elements

Low alloy steel (the total amount of alloy elements is less than 5%), medium alloy steel (the total amount of alloy elements is 5%-10%), high alloy steel (the total amount of alloy elements is more than 10%).


According to alloy element composition
(Cr-Fe-C)、(Cr-Ni-Fe-C)、(Mn-Fe-C)、(Si-Mn-Fe-C)。

Low alloy steel plate

Low alloy steel plate contains fewer alloy elements below 3.5% of total elements. Intending to add some alloy elements on the carbon steel basic for improving the steel performance. Low alloy steel plates are mainly used to manufacture plants and factories.
