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.

‌Q420D alloy steel sheet is a low alloy high strength structural steel with good low temperature impact toughness, which can meet your special engineering structure needs.

‌Q420D hsla structural steel has good plasticity and processing properties, and is easy to cut, bend, stamp and other processing. At the same time, ‌Q420D high strength low alloy steel also has certain corrosion resistance and durability, and the performance can be improved by adding alloy elements and surface treatment.

Q420D low alloy steel sheet can be used in high-rise buildings, large infrastructure projects, large span and heavy load bridges, large engineering machinery, ocean-going ships and marine engineering facilities.
