BBN steel S890QL steel equivalent chemical composition supplier

Mechanical properties of S420NL-Z35 steel plate: yield strength≥235Mpa, tensile strength 360-510Mpa, elongation≥26%. The properties of S890QL steel equivalent, S420NL-Z35 steel plate determine its application. S420NL-Z35 steel plate has high strength and good welding performance, which is commonly used in the manufacturing of mining machinery, engineering machinery, coal mine hydraulic support and other equipment and structural parts.

The effect of nitrogen on steel performance is similar to that of carbon and phosphorus. With the increase of S890QL steel equivalent nitrogen content, the strength of steel can be improved, plasticity especially toughness can be significantly reduced, weldability becomes worse, and cold brittleness is intensified. Nitrogen with aluminum, niobium, vanadium and other elements can reduce its adverse effects, improve the performance of S890QL steel equivalent steel, can be used as an alloying element of low alloy steel.

S890QL steel equivalent and so on steel structure engineering steel has good plasticity, which can make the structure have obvious deformation before being destroyed, so as to avoid brittle failure of structure. The good plasticity of steel can adjust the local peak stress to redistribute the stress, and improve the ductility of components, so as to improve the seismic capacity of the structure. The impact toughness of S890QL steel equivalent and so on steel structure engineering steel is good, which can improve the ability of resisting dynamic load and avoid the occurrence of cracks and brittle fracture.
