S355J2W high strength low alloy steel

S355J2W belongs to fine-grained steel. Fine-grained steel, also known as intrinsically fine-grained steel, is a steel in which metal materials are refined by some heat treatment methods to make their intrinsic grain size reach grade 5 to 8, thereby improving their mechanical properties. Intrinsic grain size refers to the tendency of austenite grains to grow in steel under certain conditions.
