Q355D Low Alloy Steel Plate Products Description
Q355D low alloy steel is a low-alloy high-strength structural steel with high corrosion resistance and strength. Its chemical composition is mainly composed of carbon, phosphorus, sulfur and other elements. The first letter Q of its grade expresses the yield strength of the steel plate. The following number 355 means that the yield strength of the steel plate is 355MPa, and the last letter D expresses that the impact temperature of the steel plate is -20 degrees Celsius.
Q355D steel plates comply with the GB/T1591 standard. Q355D steel plates are delivered in a non-normalized state and are generally delivered in a hot-rolled state. The production thickness is less than 400mm and the width is no more than 4000mm. Factory material certificates are provided. Q355D steel plates are widely used in buildings and bridges. , ships, vehicles, heavy machinery and other fields.
