Hot rolled steel coils use slabs as uncooked materials, and after heating, they are made into strips by means of difficult rolling devices and ending rolling units. During the manufacture of hot-rolled metal coils, the warm metal strips from the final rolling mill of ending rolling are cooled to the set temperature by using laminar flow, and rolled into metal strip coils by way of the coiler, thru special ending lines. Processed into metal plate, flat coil and slitting metal strip products.
Q235 is a commonly used low-carbon structural steel in China, which corresponds to the American standard ASTM A36 and the European standard S235JR. When referring to Q235 cold rolled carbon steel, it means that the steel has undergone the cold rolling process, which involves passing the hot-rolled steel through a series of rollers at room temperature to reduce its thickness and improve its surface finish. Here is a description of Q235 cold rolled carbon steel:
Composition: Q235 cold rolled carbon steel primarily consists of iron and carbon, with limited amounts of other elements such as manganese, phosphorus, sulfur, and silicon. It has a relatively low carbon content, typically around 0.2% to 0.22%, which contributes to its excellent weldability and formability.
Strength and ductility: Q235 cold rolled carbon steel exhibits moderate strength and good ductility. It has a yield strength of around 235 MPa (megapascals) and a tensile strength between 375 and 500 MPa. These properties make it suitable for various structural and general engineering applications.
Formability: Cold rolling improves the surface finish of Q235 carbon steel and enhances its dimensional accuracy. It also improves the steel's formability, allowing it to be easily shaped and manipulated into different forms without sacrificing its structural integrity. This makes it suitable for applications that require complex shapes, such as automotive components, construction materials, and general fabrication.
Corrosion resistance: Q235 cold rolled carbon steel is not inherently corrosion resistant and may require additional protective coatings or treatments to prevent rust and corrosion. It is important to note that the corrosion resistance of Q235 steel will depend on the environment and the specific protective measures applied.
Weldability: Q235 cold rolled carbon steel has good weldability, allowing it to be easily welded using common welding methods such as arc welding, MIG (metal inert gas) welding, and TIG (tungsten inert gas) welding. Its low carbon content reduces the risk of weld cracking and promotes good weld strength.
Applications: Q235 cold rolled carbon steel finds a wide range of applications in various industries, including:
Structural components in buildings and bridgesAutomotive frames and componentsMachinery and equipmentGeneral fabrication and manufacturingPipes and tubesStorage tanksConstruction materials
