Strip steel is a kind of steel plate with thin thickness, narrow width and long length. Strip steel can be made of common carbon steel, carbon structural steel, spring steel, tool steel, stainless steel, etc. Strip steel has the advantages of high dimensional accuracy, good surface quality, easy processing and material saving. There are many kinds of strip steel, S690QL material. Hot rolled steel strip is mainly used for cold-rolled billets, cold-formed steel billets, welded steel pipe billets, manufacture of bicycles and small hardware products.

Aspire to technological innovation and pursue first-class quality steel S690QL material products.Take independent innovation as an important support for the sustainable development of iron and steel industry, strengthen the main position of technological innovation, accelerate the original innovation, integrated innovation, introduction, digestion, absorption and re innovation, improve the technological innovation system, and cultivate the core technology and brand products of independent intellectual property rights.

A small amount of Nb is sufficient to obtain excellent comprehensive properties of S690QL material etc. steel material, because at low Nb concentration, the yield strength of steel material increases faster and is proportional to the concentration, but when the Nb content is greater than 0.03%, the strengthening effect begins to decrease. Studies have shown that when the Nb content is greater than 0.06%, excess Nb will no longer strengthen the steel material.
