Product Description

Low alloy steel plate is a general term that refers to steel plates with an alloy content lower than 3.5%. Generally speaking, low alloy steel plate is Q345B plate in the market. Alloy steel is divided into low alloy steel, medium alloy steel, and high alloy steel. As the name suggests, it is distinguished by the total amount of alloy elements. Less than 3.5% of the total amount is called low alloy steel, 5-10% is medium alloy steel, and more than 10% is high alloy steel. In China, it is customary to refer to special quality carbon and alloy steels as special steels. 31 special steel enterprises nationwide specialize in producing such steels, such as high-quality carbon structural steels, alloy structural steels, carbon tool steels, alloy tool steels, high-speed tool steels, carbon spring steels, alloy spring steels, bearing steels, stainless steels, heat resistant steels, electrical steels, as well as high-temperature alloys, corrosion resistant alloys, and precision alloys.
