A572 grade 50 or EN steel grade S460QL material, what is the difference

SPHC-The first S is the abbreviation of Steel, P is the abbreviation of Plate, H is the abbreviation of Hot Heat, and C is the abbreviation of Commercial Commercial, which means generally hot-rolled steel plate and steel strip. SPHD - It tands for hot-rolled steel sheets and strips for stamping. SPHE - It stands for hot-rolled steel sheets and strips for deep drawing. SPCC- It means that cold-rolled carbon steel sheets and strips are generally used, which is equivalent to China's Q195~Q21 grades. The third letter C is the abbreviation for Cold.

Vanadium is a weak deoxidizer. Adding vanadium into EN steel grade S460QL material steel can reduce the adverse effects of carbon and nitrogen, effectively improve the strength, but sometimes also increase the tendency of welding hardening, vanadium is also a commonly used trace alloy element.

After 1975, our equipment includes blast furnaces, electric furnaces, vacuum refining furnaces, and electroslag furnaces. The product varieties are relatively complete. Plates, EN steel grade S460QL material tubes, wires, belts, and profiles have a certain scale, including magnetic, elastic, expanded, bimetal and other precision alloy materials for national defense and electronics industries. In 1982, these plants produced 364,000 tons of EN steel grade S460QL material steel and 542,000 tons of steel.
