Welcome to BBN High Strength Steels Factory
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, S460QL1 steel grades. 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.
Q420q steel material is a kind of structural steel plate for bridges, the grades are Q420qD, Q420qE, Q420qF.
Q420q steel chemical composition: C: ≤0.11, Si: ≤0.55, Mn: 1.0-1.7, Nb: 0.01-0.09, V: 0.01-0.08, Ti: 0.006-0.03, Cr: ≤0.50, Ni: ≤0.30, Cu: ≤0.30, N : ≤0.008, Al: 0.01-0.045.Steel delivery status: delivered in the thermomechanical rolling state, and the steel plate should be trimmed for delivery.
The company adheres to green development, supported by scientific and technological innovation and technological progress, vigorously advocates the S460QL1 steel grades production and life style of saving, environmental protection, civilization and low carbon, adheres to the new industrialization road and the sustainable development road. Actively carry out international trade and maintain stable economic and trade relations with more than 80 countries and regions including the United States, Germany, France, the United Kingdom, Japan, South Korea and Australia.
Phosphorus is a very harmful element in S460QL1 steel grades steel. With the increase of phosphorus content, the strength, flexion ratio and hardness of S460QL1 steel grades steel increased, but the plasticity and toughness decreased significantly. In particular, the lower the temperature, the greater the impact on plasticity and toughness, increase the cold brittleness of steel.
