The characteristics of steel processed products mainly include the following aspects:
Light weight and high strength: The density of steel is low, but its yield strength is high, which makes the steel have a small cross-section and light weight under the same stress conditions, which is easy to transport and install. The elastic modulus of steel is also high, which can withstand large loads and impact forces, ensuring the stability and safety of the structure in various harsh environments.
Good toughness and plasticity: The internal structure of steel is uniform, with good toughness and plasticity, can withstand impact and dynamic loads, and has good seismic resistance. The material of steel is uniform and nearly isotropic, which makes its structure highly reliable.
Good processing performance: Steel is easy to process and can be processed by cutting, bending, punching and other methods to meet various complex structural design requirements. In addition, steel has good weldability and can be firmly connected by manual welding, automatic welding or gas shielded welding.
Poor heat resistance but good sealing: The properties of steel do not change much when the temperature is below 150℃, so it is suitable for hot workshops. However, when the temperature exceeds 300℃, the strength and elastic modulus of steel will drop significantly, and the strength is almost zero when it exceeds 600℃. The welded structure of steel can be completely sealed, which is suitable for occasions requiring high sealing.
Poor corrosion resistance: Steel is prone to rust in humid and corrosive environments, and usually requires rust removal, galvanizing or coating, and regular maintenance. For structures in special environments such as seawater, special anti-corrosion measures are required.
