Q390B alloy steel plate is a low alloy high strength structural steel with excellent comprehensive mechanical properties.
Q390B low alloy steel material has a low brittle transition temperature, which can prevent the material from brittle fracture when impacted or vibrated. Q390B high strength low alloy steel is also suitable for a variety of welding techniques, easy to process and manufacture, and can be used in a variety of environments, including corrosive industrial environments.
Q390D alloy steel plate is a low-alloy high-strength structural steel with a yield strength of not less than 390MPa and a tensile strength between 490 and 650MPa, which can withstand greater pressure and bending stress.
Q390D high strength low alloy plate has excellent mechanical properties, good ductility, toughness, cold forming performance and welding performance. Q390D low alloy steel sheet can be further improved through surface treatment technology to ensure the long-term stability of the structure.
Q390D high strength steel plate engineering application: especially suitable for large structural parts such as power towers, various types of cranes, heavy vehicles, oil derricks, high-temperature fans, etc.
