Ordinary low-alloy structural steel refers to the addition of a small amount or trace alloying elements (such as Si,
V, Ti, Mn, Mo, Nb, Cu, B, RE, etc.) in ordinary carbon steel, its total mass fraction does not exceed 5%, and the
steel performance changes, and the steel performance is better than the general carbon steel, such as high
strength, It also has abrasion resistance, corrosion resistance, high temperature resistance, low temperature
resistance and other special properties.
Because the total amount of alloying elements added to this steel is not large, this type of alloy steel is a low alloy steel. Its smelting method is similar to general carbon steel, and the cost is not high, so it is called ordinary low-platform gold structural steel. General low steel is a low alloy steel widely used in welding structures.
