GB/T1591-2018 Q355NB is a low-alloy high-strength structural steel. This steel has high strength, good fatigue resistance; high toughness and low brittle transition temperature; good cold forming performance and welding performance; good corrosion performance and certain wear resistance. Steel QStE380TM automotive steel coil products are delivered in hot rolled, normalized, normalized rolled or thermomechanical rolled (TMCP) state.
It has good toughness. By strictly controlling the chemical composition, reducing the content of QStE380TM automotive steel coil harmful elements and selecting reasonable heat treatment conditions, NM360 steel plate has good toughness. Therefore, the highly reliable structural parts can be constructed according to the brittle failure of wear-resistant components. Uniform and beautiful quality, QStE380TM automotive steel coil using advanced technology and equipment, combined with high and scientific technical management, the material and shape of the product are even and consistent.
If the chromium content in QStE380TM automotive steel coil alloy steel reaches about 12%, dense chromium oxides will be formed on the surface of the steel, which will greatly improve the corrosion resistance of steel in oxidizing media. Chromium, aluminum, silicon and other elements can improve the oxidation resistance of steel and the corrosion resistance of high-temperature gas, but excessive aluminum and silicon will deteriorate the thermoplasticity of steel.
BBN steel strictly control quality of our carbon steel plate, alloy steel plates and structural steel plates. For QStE380TM automotive steel coil ASTM A572 Grade 50 structural steel plate, Our Q/C Department will inspect dimension before shipment, making sure structural steel plate thickness tolerance and width, length tolerance are matchable to the QStE380TM automotive steel coil standard requirements.
