Products Description
GB/T1591 Q460D HSLA structural steel plates have good fatigue resistance and low-temperature toughness, with a Charpy V-notch impact value of 27J at -20°C, as well as good cold forming and welding performance.
Q460D steel plates mainly adapt to the production of high-strength engineering machinery, transportation machinery, construction machinery, mining machinery, coal mine hydraulic support, crane arm legs, frames, steel structures, and so on, especially for low-temperature and high-strength structural parts.
The yield strength is ≥ 460 MPa, and the tensile strength ranges from 620–800 MPa with an elongation of ≥ 18% in a 200mm specimen.
