S355J2 is a trademark of the European standard equivalent to Q345D of the national standard. It is a low-alloy high-strength structural steel. Because of its good impact toughness and weldability, this brand of steel plate is widely used in various industries
They're often stronger, stiffer, and slightly more resistant to corrosion than traditional carbon steels. Alloy steels are defined by the primary alloying materials (in addition to carbon). 4140, one of the most common alloy steels, is a Chromium-Molybdenum alloy steel.
