GET PRICEEN10025 S550 Low alloy structural steel plate
EN10025 S550 is low-alloy structural steel plate, carbon content of not more than 0.20%, making EN10025 S550 has a high toughness, weldability and cold forming properties; a small amount of niobium, titanium or vanadium in the steel to form fine carbides or carbonitrides, Which is favorable to obtain the fine ferrite grain and the strength and toughness of EN10025 S550 steel plate. In addition, adding a small amount of copper (≤ 0.4%) and phosphorus (0.1%), etc., can improve the corrosion resistance EN10025 S550 steel plate. Adding a small amount of rare earth elements, can be desulfurization, de-gas, so that steel purification, improve toughness and process performance.EN10025 S550 steel plate used in machinery manufacturing and metal structures.
