Product specification and description

Q235 carbon steel coil is a common carbon structural steel, also known as A3 steel. In the name of this steel, "Q" represents the yield limit of this material, and "235" refers to the yield value of this material, which is about 235MPa. This yield value will decrease as the thickness of the material increases. Due to the moderate carbon content of Q235 carbon steel coil, it has good comprehensive properties, including strength, plasticity and welding properties, making it widely used in a variety of applications.

The main characteristics and uses of Q235 carbon steel roll are as follows:

Excellent welding and processing properties: Q235 carbon steel rolls are easy to perform a variety of hot and cold processing processes, such as cutting, bending and welding. This makes it widely used in construction, machinery manufacturing, shipbuilding, railway construction and other fields.
Good strength and stability: Q235 carbon steel coil has high strength and can withstand most of the loads required for buildings and mechanical structures. At the same time, it also has good stability, can ensure the long-term safe use of the structure.
Good weather resistance: Q235 carbon steel coil has good weather resistance and can be used in a variety of harsh environmental conditions, such as high temperature, low temperature, humidity and so on.

It should be noted that although Q235 carbon steel coil has the above advantages, it still needs to be selected and used according to engineering requirements and specifications in specific applications to ensure its safety and effectiveness. At the same time, for applications involving important structures or critical components, it is recommended to carry out professional evaluation and testing to ensure that the selection and use of materials meet the relevant standards and requirements.

Inspection Of Steel Coil

Coil testing is an important link to ensure the quality and performance of steel coil products, usually including the following aspects of testing:

Appearance quality: mainly check the surface flatness of the steel coil, surface defects (such as scratches, pits, rust, etc.) and thickness deviation. These defects not only affect the appearance of the steel coil, but also may affect its performance.

Dimensional accuracy: involves the measurement of the thickness, width and length of the steel coil. These dimensions must meet the relevant standards and customer requirements to ensure the suitability of the steel coil for subsequent processing and use.

Chemical composition analysis: The chemical composition of steel coil directly affects its mechanical properties and corrosion resistance. Therefore, rigorous chemical composition testing is required to ensure that the product complies with the specified requirements.

Mechanical properties test: including tensile strength, yield strength, elongation and other indicators of the test. These tests are done with equipment such as tensile testing machines to ensure that the steel coil has sufficient strength and stability.

Surface coating inspection: For coated products such as galvanized steel coils, it is necessary to check the coating thickness, adhesion and other indicators to ensure the quality and anti-corrosion performance of the coating.

In addition, depending on the purpose and special requirements of the steel coil, other special tests may also be required, such as corrosion resistance testing, impact toughness testing, etc.

Material introduction

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.
