Q235 steel characteristics
steel Product Introduction
Q235 steel is a type of low-carbon steel, manufactured according to the GB/T700 standard of China. It is divided into four grades: Q235A, Q235B, Q235C, and Q235D. With a density of 7.85g/cm3, Q235 steel has a tensile strength ranging from 370 to 500 MPa and a compressive strength of 235 MPa (for steel bars or plates with a thickness of 16mm).
With an appropriate carbon content in Q235 steel, this type of steel often exhibits good overall performance and a good balance of strength, flexibility, and weldability. It is produced in various forms such as plates, round bars, square bars, flat bars, angles, channels, I-beams, and steel pipes, serving industries such as construction, bridges, ships, and vehicles.
Q235 steel is widely used in construction and engineering industries, from making steel bars for workshop structures and high-voltage transmission towers to use in boiler manufacturing, containers, and many other mechanical applications requiring stable operational performance.
