Q390B High Strength Steel Sheet(HSLA)
Q390B low alloy steel material belongs to low alloy high strength structural steel plate. The implementation standard of Q390B high strength low alloy steel is: GB/T1591-2018 special technical conditions.
Q390B high strength low alloy brand representation:
Q390B high strength low alloy hsla steel GB=national standard in the implementation standard
Q390B high strength steel implements T=recommended in the standard
Q390B high tensile steel 1591 in the executive standard = steel plate executive standard number arrangement
Q390B high strength alloy steel 2018 in the implementation standard = the year of implementation of the standard
Q390B high strength low alloy structural steel itself has a variety of high-quality properties, and the high-quality properties are demonstrated during use. Therefore, Q390B hsla steel plate is often widely used in the machinery manufacturing industry, such as: heavy industry machinery, engineering machinery, chemical equipment, Coal mining machinery, cranes, bridge structures, turbine baffles, frames, hydraulic supports, embedded parts, ship equipment, port machinery, vehicle equipment, etc.
