Product specification and description

Carbon steel square bar is a kind of square bar made of carbon steel, with high strength, hardness and corrosion resistance, widely used in construction, manufacturing and processing fields.

The section of carbon steel square bar is square, the side length is different. Its production process mainly includes hot rolling and cold drawing two kinds, hot rolling is through high temperature heating after forming and cooling, cold drawing is through mechanical stretching and cooling treatment to produce different specifications of carbon steel square bars.

The main components of carbon steel square bars are carbon and iron, of which the higher the carbon content, the higher the hardness of the steel, but at the same time may also lead to the weldability and toughness of the steel. Therefore, when choosing carbon steel square bars, different components of steel need to be selected according to the actual application scenario.

Carbon steel square bars have high strength, hardness and corrosion resistance, and can withstand large loads and wear, so they are often used in construction, manufacturing and processing fields. For example, in the field of construction, carbon steel square rods can be used to make large components such as Bridges and building structures; In the manufacturing field, it can be used to make various mechanical parts and tools.

In short, carbon steel square rod is a kind of metal material with high strength, hardness and corrosion resistance, which is widely used in construction, manufacturing and processing and other fields, bringing convenience and development to people's life and production.

Inspection Of Steel Bar

Carbon steel is an iron-carbon alloy with a carbon content of 0.0218% to 2.11%, also known as carbon steel.


Generally also contains a small amount of silicon, manganese, sulfur, phosphorus.


The American Iron and Steel Institute (AISI) defines carbon steel as having no specified or required minimum content of chromium, cobalt, molybdenum, nickel, niobium, titanium, tungsten, vanadium, zirconium, or any other element to be added to obtain the desired alloying effect; The prescribed minimum content of copper shall not exceed 0.40%; Or the specified xxx content does not exceed the indicated percentage for any of the following elements: Manganese 1.65%; Silicon 0.60%; Copper 0.60%.


Carbon steel is a popular knife-making metal choice because it contains a lot of carbon, giving blades better edge retention. In order to make full use of this steel, it is very important to give it a proper heat treatment.

Material introduction

Alloy steel is steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties.


Alloy steels are broken down into two groups: low alloy steels and high alloy steels. The difference between the two is disputed. Smith and Hashemi define the difference at 4.0%, while Degarmo, et al., define it at 8.0%. Most commonly, the phrase "alloy steel" refers to low-alloy steels.


Strictly speaking, every steel is an alloy, but not all steels are called "alloy steels". The simplest steels are iron (Fe) alloyed with carbon (C) (about 0.1% to 1%, depending on type) and nothing else (excepting negligible traces via slight impurities); these are called carbon steels. However, the term "alloy steel" is the standard term referring to steels with other alloying elements added deliberately in addition to the carbon. Common alloyants include manganese (Mn) (the most common one), nickel (Ni), chromium (Cr), molybdenum (Mo), vanadium (V), silicon (Si), and boron (B). Less common alloyants include aluminium (Al), cobalt (Co), copper (Cu), cerium (Ce), niobium (Nb), titanium (Ti), tungsten (W), tin (Sn), zinc (Zn), lead (Pb), and zirconium (Zr).


The following is a range of improved properties in alloy steels (as compared to carbon steels): strength, hardness, toughness, wear resistance, corrosion resistance, hardenability, and hot hardness. To achieve some of these improved properties the metal may require heat treating.


Although alloy steels have been made for centuries, their metallurgy was not well understood until the advancing chemical science of the nineteenth century revealed their compositions. Alloy steels from earlier times were expensive luxuries made on the model of "secret recipes" and forged into such tools as knives and swords. Modern alloy steels of the machine age were developed as improved tool steels and as newly available stainless steels. Today alloy steels find uses in a wide array of applications, from everyday hand tools and flatware to highly demanding applications such as in the turbine blades of jet engines and in nuclear reactors.
