Common steel bulb grades mainly include Q235B, Q345B, SS400, A36, and S235JR. The differences between these steel bulb grades lie in their chemical composition, mechanical properties, and the specific country/regional standards they comply with. Different grades of bulb flat steel have different hardness, strength, toughness and corrosion resistance to meet different engineering requirements.
