Q420B Alloy Steel Plate
Q420B High Strength Low Alloy Plate Products Description
Q420B high tensile steel plate is a low alloy high strength structural steel plate, which complies with GB/T 1591-2018 standard. Q420B high strength plate adds a small amount of micro alloying elements such as Nb, V, Ti to carbon steel to improve strength and comprehensive performance.
Q420B high strength low alloy plate has high toughness, can withstand large impact loads, maintain structural integrity, is suitable for harsh environments, and reduces maintenance costs.
Q420B high strength steel plate is widely used in construction, bridges, machinery manufacturing, automobile manufacturing, energy engineering and shipbuilding.
