Q420 I Beam Products Details
- Mechanical properties
- The yield strength of Q390 I-beam is 390MPa and the tensile strength is usually above 490MPa, which makes it perform well when subjected to large loads and high pressure. In addition, it has good plasticity and toughness and is not prone to brittle fracture.
- Machinability
- Q390 I-beam has good weldability and cold forming properties, suitable for welding and cold bending processing. The strength of the welded joints is close to that of the parent material, ensuring overall structural integrity and stability.
- Corrosion resistance
- Q390 I-beam has excellent corrosion resistance and can maintain its mechanical properties and appearance quality under harsh environmental conditions. Through appropriate anti-corrosion treatment, such as spraying, galvanizing, etc., can significantly improve its corrosion resistance and extend its service life.
Q420 I Beam Products Applications
Because of its high strength and good toughness, Q390 I-beam is widely used in large steel structure buildings, bridges, high-rise buildings, factories, warehouses, exhibition centers, airports, and steel structure plants and other large-scale construction projects. In addition, it is also used in the manufacture of various mechanical equipment and parts, such as ships, vehicles, machinery and other engineering structures.
