S420m material is a fine-grain weldable structural steel that has been thermomechanically rolled. It conforms fully to the EN 10025-4 standard. S420m plates are used in welded structures, large boats
Oxygen is a harmful element in EN 10025-6 S500Q high strength steel steel. With the increase of oxygen content, the strength of EN 10025-6 S500Q high strength steel steel increased, but the plasticity
Q345 steel has good comprehensive mechanical properties, acceptable low temperature performance, good plasticity and weldability. Q345 steel is used to make mechanical parts, building structures, gene
Heat treatment is a very important process to improve the performance of S690QL steel etc. metal materials. The process of heating, heat preservation and cooling the steel in solid state to obtain the
Composition of low alloy steel plate: Low carbon: due to the high requirements for toughness, weldability and cold formability of low alloy steel plate, the carbon content is not more than 0.20%; mang
Vanadium is a weak deoxidizer. Adding vanadium into EN 10025-6 high strength steel S690Q steel can reduce the adverse effects of carbon and nitrogen, effectively improve the strength, but sometimes al
Q420B material is a low-alloy high-strength structural steel. EN 10025-6 equivalent grade, Q420 is not high-strength steel, it is still low-carbon steel. Its tensile strength has been improved a bit.
